Prometheus get only last value. That is, it only shows the most recent value.

Prometheus get only last value How can i change the query to get that list of values? Hello, I’m looking for a way to get a label’s value as query result rather than just a 1 or a 0 I’ve been knocking my head all around the web for hours but I’ve yet to find a definitive working answer. 1, and have tried various configurations I cannot get it to just show the ‘version’ . get the max out out of it. returns only values where foo matches the max value of foo in the last 2h interval. Set in configuration of you panel Value options > Calculation > Last* (Last non-null value), and you'll see last metrics value of previous day What Grafana version and what operating system are you using? v9. Any Using grafana-agent to scrape the metrics from my application. Here is my example 1 (Battery Power): The Battery was full around 13:00. with ES data source and have a dashboard that displays single stats and graphs for server status overview. Is there any way in prometheus to calculate average over the data points at the same of previous 7 days? label_values(instance) (this variable has support for ‘Multi-value’) What we can’t achieve though is: when we select more than one instance, the graph is created only for the last instance - we’d like to have different lines for each instance. NOTE: These API endpoints may return metadata for series for which there is no sample within the selected time range, and/or for series whose samples have been marked as deleted via the deletion API endpoint. For example, the following value would return the maximum value for site_logged_in metric over the last year: max_over_time(site_logged_in[1y]) Unfortunately Prometheus doesn't provide the function for returning the timestamp for the maximum value. the one more far ago in time (possibly the 1000-th element)? Currently there is no way to get the value of a counter in the official Golang implementation. I want to compare the last timestamp of a non-null value for this counter to a different ts. I have a label cs_job_time in Prometheus/Alert Manager and would like to send an email alert when a condition is met for another job. When you graph your counter you're probably not going to want to graph the raw value. metrics / prometheus) in a singlestat panel. Extract Prometheus Metrics in Go. Modified 11 months ago. {job="foo",instance="bar"}, {job="foo",instance="baz"} etc. I disabled this in Grafana by setting Time Range -> Last 0s. 000. Prometheus query to get the value of a metric since midnight or a dynamic offset. Find duplicate labels in prometheus. This query aggregates the rate of HTTP requests over the last 5 minutes, Filtering CPU metrics to only display values above a certain percentage helps identify when a system is I am using the windows node exporter, and it contains a label value of ‘version’ with the windows_os_info query. What I want to do is extract the metrics which reached 0 (ink is finished) and started from 100 (full ink). In this case Grafana would query only a single point per day per each matching time series. select time series with node_load1 name and with instance="host1" label and with instance="host2" label and with instance="host2" label. Viewed 958 times This will switch Grafana from using api/v1/query_range to api/v1/query, and Grafana will automatically query Prometheus only for the most recent data point. For example, the following query returns a single time series with the maximum value out of multiple time series which match my_metric{app="foo", state="active"}:. To use subquery feature in Prometheus in order to limit increase() calculations to per-day boundaries: Sry but I still don't understand. Is there any way to get the timespan (e. Meaning, get the most latest value according to time from the query results. values of metrics are stored in "values":[] array. If you want obtaining exact values from increase() function, then try VictoriaMetrics - Prometheus-like monitoring solution I Is possible to query only for the last value (or n-th value) of the results of a query? For example, in the query: SELECT value FROM response_times WHERE time > now() - 1h limit 1000; Is possible to get only the last value, i. But if the counter ever resets, then you will get nonsense values (huge negative spikes). Ask Question Asked 6 years, 3 months ago. the metric will only increase as long as the providing service isn't restarted. BUT I want now the difference between the last two values, independently from the specified time. *. You can use the Grafana templating to get the unique values for specific tag of some metric. I have a telemetry system that sends data into Prometheus when the data changes (i. Prometheus Query to get distinct value in the last one day. You should be using the increase() function which is specific to counters. prometheus; Share. At the very least, have you explored this page?Open up any of the queries and then build / test / modify the query, or see the “Kick start your query” button. const subject = new Rx. 3"} you will get the list of pods with version 1. Group by time and aggregate in PromQL/MetricsQL. On the other hand, looking more closely into your metrics - I'd say Prometheus is a wrong tool for the job. 000 - 607. – Perfect_Comment. That is, it only shows the most recent value. 2. 0. PromQL. 5. This guide covers advanced techniques, practical examples, and optimization strategies. Prometheus get the max value per bucket. My Prometheus server collects data from this endpoint every 30s and so I lost a lot of data and maybe also the "failed", that occurred because the next push was a status="started". 2. *server"} To select all HTTP status codes except 4xx ones, you could run: http_requests_total{status!~"4. In my application I have a replaysubject that's used throughout. I did set the flag to 30s, so from a dashboard perspective, the end user doesn't have to wait 5 minutes to see the metrics disappearing. If you can get the data exposed as a unix timestamp then you can use the max aggregator to get the highest value. ) it will compare the value of a and b. The gauge metric type allows you to record the current value of a metric, such as the queue size, and update it as the value changes. What I need is a single result instead of N (3 in my case) returning as value the label’s value. remove('bid', symbol, 'BinanceProdUSDM', 0) It seems like there is no I need to build a Grafana chart that shows the number of completed test runs by status for a specific branch. This is known issue. If you want to return all the unique values of a specific label (e. Consider a Prometheus metric foo_total that counts the total amount of occurences of an event foo, i. Every point will show bytes usage over the previous day ending at the point. If you tried to use last_over_time to mediate your problem Another update on very latest kube-prometheus-stack using grafana 8. – You could use the or binary operator to get both values, the small caveat is that very likely your query and the last value of the metric share the same label set, in which case the or operator returns a single operand:. If the metric can have other values, then the solution doesn't work :( In this case it is possible to use subqueries. Add a comment | 1 Answer Sorted by: Reset to this will take one value per This function only acts on native histograms, which are an experimental feature. The problem is that topk returns k elements at each evaluation step over the time frame of the query and there is no guarantee that the elements will be the same over the entire time frame. value like max. , method) from the http_requests_total metric, you can use the label_values function in conjunction with the Prometheus UI or Grafana. 000 = 77. The exact extent of additionally returned series metadata is an implementation detail that may change in the future. These functions will almost always result in values that aren't whole numbers, this is even true for the increase function. Viewed 2k times 0 . I can also query this last_seen value at any time. If you need to return an arbitrary time series out of multiple matching time series, then this can be done with topk() or bottomk() functions. The table doesn’t need to be a live view and could use a rollup of 5 minutes or an hour if needed. Improve this answer. I have been publishing execution time metrics in an Histogram from my application, but I would like to also get the max. I am wondering how can I the first velus from the query result? Actually on server restart prometheus values get reset to 0, so the graph suddenly drops, if we see the increase of 24 hr, it comes inaccurate as it is the difference of the first and last value , any better approach to this ? To get the exact count for the last 24 for hours I have created the following query: max_over_time(http_requests I am using Grafana 4. So when sending the PromQL query, we still see the last value scraped . This may lead to incorrect results Below is a snippet that describes what I'm trying to do. If a is smaller, you get its value. 0. 8] Get table column to show "last" value when underlying data is null. I have a counter metric that only fires in rare cases. NewHistogramVec(prometheus. Share. It is not clear to me how to do that as using ES the queries contain time range and there are options to display I am trying to get some metrics out of a Victoria DB, specifically some printer metrics monitoring the amount of available ink. Other values are filtered out. Use Prometheus built-in <aggregation>_over_time For example, if the current load at 6PM is 10000 RPS, I want to compare the current load with average of 6PM data points over last 7 days. I still faced this issue, for me in a Bar gauge I still had this issue in scenarios where it only returned 1 value, but with 2+ values the Legend field works OK. I need to have a table panel which shows when the job completed last. 3” to display it in a Grafana Dashboard. It fails to show anything if I try to sum different values, see the attached image. See matching rules for binary operators in Prometheus. Now it’s 13:46 and the line doesn’t continue, because there’s now powerflow into or out of the battery and because of that the value hasn’t been updated since 13:00. You need to use or operation for Is there a way to get the label values as the Value of a prometheus query. Is there anyway I can achieve that? Prometheus QL get the first values from the query result. I have a couple of Stat panel where I want to show the absolute latest / current value for a metric from Prometheus regardless of the general time range of the dashboard. The increase() function in Prometheus may return fractional results for integers counters The only cost is the additional zero element at the beginning of the custom values list. Thank You in advance. For example, i need to filter out the instances which has more than 80 % CPU usage. its a push-on-event mechanism, not a sample/interval push) That means, if a system is stable, then the last reported value can be reported quite some time back. It’s required to show “Estimated Value” for a last hour only. Here’s I’m running batch jobs and when the job runs it updates values with 1 and other times zero. Example: initial range vector values = (3000,4000, 7000, 8009) adjusted range vector values with rate for each second (values are guessed) = (40, 70, 40) max_value => 70 messages processed per second Latest / Current Value for Single Panel Hi. 21. This is to spot hosts that have gone offline, or missed some arbitrary check-in time frame. I would put an image here of how that looks but but I'm a *new user* and *new users* only get 2 photos per post. insertYourLegendValueHere} I’m also running into this issue. I've tried using the Null value: null as zero option under the Stacking and Null Value section of the graph in grafana. I would like to count the number of times the value is 1 (for example) for the last 24 hours. However, Grafana would change this and by default - when creating a Table - add a timespan and look up more values. I can push to Prometheus or let it pull. Additional info: Using prometheus. Observations greater than the last custom value go into an overflow bucket with an upper boundary of +Inf. HistogramOpts{ Name: "example_request_duration_seconds", Help: "Histogram Hey! Ok so I have a energy sensor that resets each day.

Avoiding slow queries and overloads How can I get the last coverage value across different pods, so that I can get the value 90. 3. I have 2 query like this: query A: autoscaling_group_desired_capacity{monitor=“autoscaling_group”, is_cloud_provider=“True”, cluster_name=~“. So I simply want the value before each Trying to explore the option of comparing the CPU usage of last and current week via prom query node_cpu_seconds_total Let me know if anyone came across such scenario. I wanted to ask if there's a way or to propose it, so we could have functions for the dates, and not just the values. increase(m[d] @ t) If the metric is a gauge, then just substitute increase() with delta():. When they check in I get a websocket message from their hub with a new last_seen value. 3 Welcome @jameszrepo. Dashboards. The tool I’m gonna use to draw the graph is fine with strings. I have a Gauge metric defined in TypeScript: this. Consider logging systems instead. 3 (cae5c5e46b) with Prometheus (not sure which version) I am trying to create a dashboard table that shows when the last data came from an instance. How are you trying to achieve it? I An Instant query returns only the latest value that Prometheus has scraped for the requested time series. I updated all the docker images today to the most recent images I’m trying to show last values and then averages of the last values in a gauge. 0: 28: February 8, 2025 Max_over_time with sum. Average over last 7 days will not be right as we have peak time and low time. Samples that are not native histograms are Prometheus doesn't provide functionality for converting label value to time series value. Member Profile; All Messages By This Member #2646 By adjusting the query so it only queries for the last point, and that depends on your data source and how you want to control time range (override time on panel or use dashboard time) What Grafana version and what operating system are you using? v9. "Reset" metrics each day (Show only today's data) Prometheus. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company I would like this timeseries graph to chart zeros if a device is not reporting rather than showing a flat line of its last value. The email sends fine but is it possible to include the value of It will return change only if there are no changes for the last 30min. However, when I try this: avg(-delta(not_processed_records_total[24h])) Prometheus get last value recorded for metric. More details: By the prometheus tag I guess you are working with this db. Honestly, I'm not entirely sure (new to Prometheus) why I'm getting two values. Prometheus query for last local peak value. The questions I’d like Grafana to answer are usually “Which devices are currently considered This query seems to only give me the latest value within that 2-hour interval specified in the query. Getting a count of distinct label values in prometheus/grafana. I tried with the keyword “without” without no success. Trying to show a graph with the max (worst) latency in each time interval (5m), using micrometer and Grafana (less relevant IMO) with Prometheus look into max_over_time, tried few options but numbers looks I have a use case where I want to set the alerts from grafana on hourly basis. 8, self-hosted on a GKE cluster What are you trying to achieve? I’m using the Istio Mesh dashboard, where multiple Prometheus queries are merged into one table panel. Query most recent values for active & stale Prometheus timeseries over range It's now possible with the help of the PromQL @ modifier. metric_2{domain="exmple-0,1,2. This sounds awfully simple The way the expression works is that for every label combination (e. How can I configure the table to only display the last value recorded? Torkel Ödegaard. For example, it can return fractional results when applied to a counter with only integer values such as http_requests_total. The rows in the bar gauge are not sorted. 21 72. 34. The “instant” option is checked. delta(m[d] @ t) These queries use @ modifier for fixing the end of the time range at t. 6) # Increment by given value How might I get the value of the c metric after performing both of these increments? This is for testing purposes, I want to be I would say it is not possible. Note that node_load1{instance="host1",instance="host2",instance="host3"} won't return any results, since the label filters are applied with and operation, e. 31 From the prometheus python documentation, let's say I run this: from prometheus_client import Counter c = Counter('my_failures', 'Description of counter') c. If you need exact integer results, then take a look at MetricsQL from VictoriaMetrics. There’s two ways I found to get what you want. But not all values are present at the same time (issue resides in Prometheus due to federation). I am running a diskspace used query in Prometheus and would like to return only the top 5 or 10 entries from the search result. I guess you need to store the value of the gauge in a common data store (db, redis,) and then provide the gauge from all of the workers (all with the same value and then you don't have to care which timeline you show (simply show with last() I get (as you said) the last value. Query is the most common type of Template variable. With this query, i get all the samples in the last 24 hours: sample. g. Ask Question Asked 11 months ago. It looks like you don't want metrics, but rather per run info (and metrics, and especially Prometheus, don't play with that idea well). runStatusGauge = new Gauge({ name: 'test_run_status', help: 'Test run status', labelNames: ['runName', 'status'], I am trying to find a way to write a query in grafana which will display only the highest of three values (coming from kube. on the screenshot above, the last value is about 607. Thanks, Rémy Here expectation is to get only 1 value for 1 pod, which is to be maximum. Proposal. *"}) but of course, this doesn't work as labels are strings. Instant queries can return results Using regular expressions, you could select time series only for jobs whose name match a certain pattern, in this case, all jobs that end with server: To select all HTTP status codes except 4xx Let's say this metric is called "my_metric", how do I get its last reported value without specifying manually the timeframe to look back? So far I come up with the following To write a Prometheus query that returns the value of a specific label, you need to use the basic syntax for querying metrics and utilize the appropriate label matchers. Last Value Gauges. This is not a very metricy question, and so is hard to answer with Prometheus. Now we need to handle the cases where a system switched a group. it's actually pretty unlikely that there'd be any repeated values in the output of a rate. Muhammad Saad. I wonder if it's possible to gather max. 7 What are you trying to achieve? get the last value, so there is always a value displayed, even if not: What happened? Due to API Limitations I can The solution provided in this answer works only for up-like metrics, which can have either 0 or 1 values. All the options I'm seeing to displaying the data are grouping methods like max, average, sum and so on. ) The last custom value MUST NOT be +Inf. This sounds like a use case for the pushgateway, which is intended for cluster-level batch jobs like these. We have to set the interval to be the same size as the plot to ensure we get the max of all the displayed values. To query Prometheus, you use PromQL (Prometheus Query Language). which returns only hosts with the increased CPU usage by at least 10% during the last week: See more information about the "offset" modifier in the Prometheus The only idea I have is to get everything via /api/v1/query and perform some sorting and filtering with a lot of logic which seems to me like an AI invention? cause the query will return a huge amount of data even with timestamp not a range. In that case you need to decide if you want to have that counted for A or B. (So the current time is definitely not a local peak) (p: peak point, i: cornjob interval, m: missed execuation) PromQL doesn't have a mode function, and in general it wouldn't make sense as Prometheus takes samples via scrapes so it doesn't have the total knowledge required to correctly calculate the mode , and due to noise etc. Hot Network Questions gives us all the metrics that existed only in one group within the last hour. Additionally, Prometheus ignores the difference between the last sample on the previous day and the first sample on the current day when calculating increase(). Analysis: Label values often contain important metadata about your metrics. I tried to use last_over_time as in last_over_time(my_metric{type="user"}[5m]) In such situations, I usually need to know how the metric's value changed, say, in 24h. vector1 or vector2 results in a vector that contains all original elements (label sets + values) of vector1 and additionally all elements of vector2 which This function only acts on native histograms, which are an experimental feature. I think you can use the at modifier (@) introduced back in 2021. "} Subquery Maybe what you are looking for is count_values. The start of the time range - t-d - is adjusted with the d I am using PromQL to get the values of a counter for the last 5m minutes but I would like to get the counters delta value for each value returned.

I just want something like panels_meters[0] - panels_meters[1] assuming panels_meters as an array of data sorted chronologically inverse. On the other hand, if I use an instant query, I only get the values for a specified moment, thus I’d need to shoot multiple queries & first find out when some time series (red circles) were marked stale - which doesn’t seem great either. Why do some prometheus metric values return +Inf. How do I sort them in desc order? What Prometheus query (PromQl) can be used to identify the last local peak value in the last X minutes in a graph? A local peak is a point that is larger than its previous and next datapoint. Lets say it might have changed 5 times in the last 24 hours. net to push metrics to prometheus' push gateway. This query uses last_over_time() function for selecting all the time series, which were active during the last day. Prometheus can return unexpected results from increase function. the query means:. Count how many times an event occurred or a metric was reported using PromQL. That makes it easier to alert on as you can do time() - some_job_last_success_seconds > 86400. topk(1, my_metric{app="foo", state="active"}) But when I take a look on the gateway's /metrics endpoint, then I only see the last value instead of all the submitted values over time. 1: 4530: September 30, I have a metric that is ingested frequently but the value doesnt change too often. 4k 14 14 gold badges 61 61 silver badges 183 183 bronze badges. Time series can stop receiving To get an exact difference between the value now and the value 5 minutes ago, then you can use "foo - foo offset 5m". I can find ways to write prometheus queries to filter data points based on the value of a label, but I haven't yet been able to find a way to tell prometheus to return time series data points only if the value of the metric meets a certain condition. if best_bid == 0: own_price_gauge. I need the list of ip addresses as the output. If you want the number of requests, not the rate, you can use increase function, which acts like rate but without dividing by the time. lmq1999 October 2, 2023, 2:57am 1. Prometheus may return unexpected fractional results for integer-only app_ui_card_open metric because of extrapolation. I merge multiple Prometheus queries into one table panel (instant option checked). base_jvm_uptime_seconds{kubernetes_name="namepspce1"} However, it returns multiple values, so the grafana returns "Only queries that return single series/table is supported". I was initially using the max(increase(max_metric Using regular expressions, you could select time series only for jobs whose name match a certain pattern, in this case, all jobs that end with server: http_requests_total{job=~". There we can use the and operator, metricA and metricB returns you the values of metric A where also metric B exists. state. If Prometheus contains multiple time series with the dell_hw Your issue is that your label (critical, high) values (0,12) should be represented as metric values. 4. When you send a query In querying in Prometheus, how can I get the last value of a counter metric by query? Regardless of time! What is the total amount? thanks. Hi there. If you want to see only 1 time series instead of 3 you either have to filter so that you end up with a single series or you aggregate them together for example with sum() or avg(), generally. Graph for 2 instances Assume I have a histogram metric: requestDuration = prometheus. 3. Omg I added the “Please note” because I was afraid someone would have focused on the picture and miss my point 😂. currently, I have many checkpoints with label: cluster, service when I have expr field in prometheus file like: up == 0, and in 1 minute, I have many new "up" value return from my endpoints, some fail, some success, is that up == 0 only check the Prometheus provides the up() function which tells you if a target is up or down. If b is smaller, then the expression a < b won't return anything for that specific label combination, but the or b will return the value of b. {job="prometheus"}[1h]) > 0) * 1000 But I cannot figure out how to get the timestamp at which my metric last changed it’s value. Prometheus skips the delta between the last sample before the lookbehind window and the (http_requests[5m]) but I only get the single value from the array returned instead the delta for each Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company This will result in a series after a metric goes from absent to non-absent, while also keeping all labels. 5 Extract Prometheus Metrics in Go How to extract ATOMIC_POSITIONS of only symmetry inequivalent atoms after vc-relax calculation? Note also that Prometheus may return fractional results from increase() over integer counters because of extrapolation. 5. Verify prometheus metric was updated. 3"} 1 How you can fix it: Query mentioning version: query: fabric_version{version="1. If you need the exact integer results, then try this query in VictoriaMetrics - this is Prometheus-like monitoring solution I work on. In my case, I want to filter for a value Hi there, I’m trying to find a way to unpublish a value when there are no orders on the market. templating. This overflow bucket is added with an index equal to the length of the custom values list. P. I either get query execution errors when trying to filter results, or end up getting Prometheus get last value recorded for metric. Set your query to instant in Grafana. Breaks in monotonicity (such as counter resets due to target restarts) are automatically adjusted for. This returns the sum of GET requests grouped by their status codes. An Instant query returns only the latest value that Prometheus has scraped for the requested time series. Is it possible or will the Value column will only be the metric values. Expected output: Value 10. 0: 4616: November 15, 2019 [Grafana v9. Use the Query template type to generate a dynamic list of variables, I have some battery powered devices that report in irregular intervals that they are still there. Since 2. ”} I return no value since it map all label-value from query A to only 1 I would like to retrieve a single record to use the last “version” label. If you really need this functionality, then take a look at label_value() function provided by VictoriaMetrics - this is a Prometheus-like monitoring solution I work on. delta should only be used with gauges. Armali. E. Instant queries can return results much faster than normal range queries and are well suited to look up label sets. I don't really have much temporal granularity anyway because the devices are only reporting every couple of minutes/hours to conserve battery. So what are my options to filter by label value if I want to use the greater than operator? Next I need to make query over 2nd metric using host values from 1st query. Viewed 12k times When you query your metric eagle_container_resource_requests_cpu you get the latest value, e. 19. It does not give me the total average for all scrapes of that metric within the 2-hours. next(1); subject. If I use the same value Good, BUT how get values metrics only one instance? prometheus; Share. Within the bar gauge grafana options, I've selected "Value options/Calculation" to be Last (last non-null value) but that doesn't seem to make a difference. At a certain point I want to get the last value emitted from the subject, but last doesn't seem to work on a ReplaySubject. If that were the structure of your metrics, then you would be able to aggregate (sum) values. Grafana has some automatic rounding behaviour, or I am using Grafana and prometheus and I am trying to get the timestamp at which a given metric last had it’s value changed. This metric can be shown as: fabric_version{,version="1. It will only return values that where scraped between 23:00 and 23:59. metric. I want to display current value in all single stats. Note: use integral type and atomic to avoid concurrent access issues // declare the counter as unsigned int var requestsCounter uint64 = 0 // register counter This is because Prometheus performs a op b query over time series with identical sets of labels at a and b sides. Follow edited Nov 15, 2018 at 13:36. Prometheus is more focused on overall state rather than an individual event, such as a scrape failure. However I remember there was a function to display the value as “Last (Not Null)”. lookback-delta flag (5 min), makes Prometheus marking the metric as stale for 5 minutes. But I only want the five distinct values in that time period. I’m able to I’m trying to show last values and then averages of the last values in a gauge. returns the average values for raw samples stored in Prometheus over the last 2 hours. execution time within/per minute. 0: 534: March 15, 2022 Calculate start timestamp and end . I guess i failed 😆 All good 🙂 As said the representation on the graph is not the point of my question. prometheus; promql; or ask your own question. Modified 6 years, 3 months ago. Step 2: Return Values of All Unique Labels. histogram_avg(v instant-vector) returns the arithmetic average of observed values stored in a native histogram. inc(1. next(4); Prometheus get last value recorded for metric. In the example above, I would like to get the version “21. next(2); subject. I am running grafana 7. Is this the only way to get the last value of a series, or maybe there is another alternative Prometheus. Grouping: Labels allow you to aggregate data across different dimensions. Learn how to get value from Prometheus metrics in Grafana when the information you need is in the labels, not the numeric values displayed in your graph. I think some people must have encountered the same problem with the “go_info” metric. Exemplars And I want to get only the metrics where the timestamp is greater than some value, how can I do it? I was thinking of: count by (deployTime, foo) (my_metric{deployTime > "1603284799", foo=~". value within a histogram by using PromQL. org"} So the question is, how I can pass label_values to 2nd query? As far as I understand, I can use label_values() only for variables in grafana panel, so I can't write one query that will do that for me. It's more common to graph the result of a function like irate, rate, or increase. select distinct (a) from (hello_info) where value == 0 prometheus; grafana; Share. I would suggest pushing the timestamp at which it last succeeded rather than a 0/1. t], then the following PromQL query can be used:. Modified 3 years, 7 months ago. We have nice functions to handle the values, max_over_time, count_over_time, etc. So the delta is 684. 128. It's not super intuitive, but my understanding is that it's true when the series themselves are different. Note that Prometheus may return fractional results from this query even if my_app_login contains only integer values. count(last_over_time(cpu_usage[d] @ t)) by (job) This query uses the following PromQL features: count() aggregate function for counting the number of time series per each unique job value. How do I only present the last value? Thanks! Hm no at 00:00 its at 0 kWh since this helper does resets at the start of each day. It may also stop returning series with more recent samples if there are staleness markers exist after these samples - see these docs for details. In the original query the set of labels weren't identical, because they differ by code label value. . last_over_time((max_over_time({job="x"}[3m] offset -1m) == {job="x"} > {job="x"} offset 1m) [6h:]) Here: inner part checks that current value is maximal over period [now-2m, now+1m] and strictly bigger than value a minute ago. ReplaySubject(); subject. Prometheus supports a special type of gauge called a last_value_gauge. The highest value over the specified time range can be obtained with max_over_time() function. For example, to get unique methods used in Some exporters, which put their own timestamps on samples, get a different behaviour: series that stop being exported take the last value for (by default) 5 minutes before disappearing. 000, and 24h ago it was about 684. 3" is a label of your metrics, the value of the metrics in 1. 733 1 1 gold badge 9 9 silver badges 32 32 bronze badges. There are also functions like topk but people cannot recommend you the right thing without knowing more about your use case – trallnag Now, we can see that rate (which is (last value in time - first value in time) / time between those points) would be one, since (241 - 1) / (240) == 1 (the denominator is four minutes, since that’s the time between the last and first point). Have your batch job push the value just before it terminates. this is an actual request you send by using Prometheus graph execution: I’m new to all the software I’m using: grafana, prometheus and home assistant in docker-compose on a linux system. The series will last for as long as offset is, so this would create a 15m blip. I have a metric (gauge) that describes the state of my system, with few Integer values. A last_value_gauge is a gauge that records the last value that was observed for a metric. I am new to Only when they are above zero are they interesting. My solution: Go to Edit Panel, find Display Name, type ${__field. Prometheus Python see current value of metric. I tried last_over_time(test_coverage{project="a"}[1w]) Get data from prometheus only from last scrape iteration. next(3); subject. If I don’t do that then I will get a graph that shows 30K and the best price at 0 so the range will be too big, meaning we cannot see the price very wel. last_over_time stretches existing I write the query below to get the up time for the microvices. e. I want to always have displayed data in that table. Commented Mar 24, 2021 at 16:41. Ask Question Asked 3 years, 7 months ago. I cannot manage to find it. Querying label values is important for several reasons: Filtering: You can select specific subsets of your data. 1. I don't have much experience with Grafana, so I don't know what metric format (like up with 1 as value or last_seen with timestamp as value) are the most convenient ones to work with. For example, the following query returns an approximate duration in seconds when the metric temperature had values greater than 20 during the last day: "version": "1. How to filter prometheus query results based on the maximum value in a time range? 6. To get the output in the desired format, we can add a floor function to truncate the timestamp to the beginning of the day: floor(max_over_time(sum(increase(mymetric[1d]))[10m])) This should return the output in the format YYYY-MM-DD 00:00:00, value. 123. labels. I have tried using max(), but this only returns the highest value of a timeline of a single metric. s. The max_over_time function ensures that we get only the last value of the day. I’ve found the topic been asked on different websites (including but not limited to stackoverflow and github of course) and tried everything suggested without success. What are you using to produce the metrics? For example, if I select "last 1 hour" in the grafana interface, how do I get the raw change for this value in the last 1 hour? If v2 was at 300 and v4 was at 40 1 hour ago, and now they're respectively at 400 and 44, how do I actually get "100" and "4" (the raw increases in the timeframe) as values for a grafana gauge? Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company The changes() function in Prometheus can be used instead of increase() function if you are sure that the counter stays the same or is incremented by 1 between scrapes. Turns out Prometheus does this by default. capacity[24h]. Why is the absolute magnitude of Venus only slightly dimmer than its peak apparent magnitude? Prometheus is a system for working with numbers, and "12/10/2021" is a string rather than a number. For Prometheus these are 2 different Timelines and there is no way to find out which is the "correct" one. But I would like to find the time when the value changed, specifically to find how long a target has been up (or down). If the counter is incremented by more than 1, then changes() will return lower results than increase(). If I use the same Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time. I have multiple other use-cases in which I would appreciate both the ability of selecting the last value (of all times) and measuring time duration from now to the series data point. Something of the form trivy_vulnerability{severity="high"} 12 and trivy_vulnerability{severity="critical"} 0. rate() and increase() skip over those counter drops and calculate a rate using the remaining data points. Grafana v8. For that we are going to leverage the @ end() modifier that allows to take the value of the last evaluation interval. So, for example, if 60 (from instance b) is the most recent one, that's what I want to return, ignoring the other instances. Prometheus get last value recorded for metric. Learn how to filter Prometheus metrics by value for precise monitoring. See this issue for details. You can count how many times this has changed in a given time-period using changes() and you can even use avg_over_time() to see what % of the time it's up. 4. inc() # Increment by 1 c. I want to see this number in a Stat widget. Victoria metrics - metrics associated to a label. Is there a way to get only the latest most updated value from that table? And to always display it? You can use query like this to get last peak value. You can also avoid double counting by incrementing your own counter and use an CounterFunc to collect it. If the monitored service is instrumented with a Prometheus client library that supports it, process_start_time_seconds may do what you need. Follow This way I get the metric value from the left-hand side vector as per documentation: Prometheus query to get the value of a However, the default value for query. The track_timestamps_staleness setting can change this. Even on In grafana time series dashboards the grafana is showing the last value if the query doesn’t return any value to it As I’m using Prometheus data source and I have Oracle SQL query so for example 12-10-22 if the source_name has 3 count and on 13-10-22 if the source name has no count but on 13-10-22 the grafana shows 3 count still in time series graph and If you need obtaining the increase of some counter metric m over a time range (t-d . If you upgrade to Grafana 9 or higher, there are PromQL helper functions that may help you. last_over_time( ) - returns Hello all, I am trying to execute query where i get the max value of timer’s max over a certain period of time. For example, over the last 12 hours for the develop branch, 12 runs passed and 3 runs failed. io/docs/prometheus/latest/querying/functions/#aggregation_over_time Is it possible to display one query result for the last time step only? e. Improve this question. The behavior of this function may change in future versions of Prometheus, including its removal from PromQL. 4 Likes TLDR; Template with query label_values(tag_name1) would do the job. So this won't trigger when the value changes, for I'm new to using Grafana and I'm trying to display the last value of a table that's organized by dates in a Gauge visualization. amount of seconds) since the last increase of that metric? I know that due to the scrape period, the value for sure isn't that accurate, but an accurancy of Get data from prometheus only from last scrape iteration.

This can be useful for metrics and I want to get all unique label values Kind of like. Prometheus: how to get label_value() in query. In this hourly alert I want to get the request count for each API in last 1 hour and collect them and sent along with the alert. Currently, the topk() query only makes sense as an instant query where you get exactly k results, but when you run Getting last prometheus value with grafana. 0(March 2021) prometheus release, 'last_over_time' allows you to retrieve exactly what you need: last_over_time(my_metric[14d]) Docs: https://prometheus. So, basically, metric_name query is somewhat equivalent to count(count(last_over_time(hello_info[1d])) by (a)) The custom interval - 1d in the case above - can be changed to an arbitrary value - see these docs for possible values, which can be used there. For the time-series-panel I need more than one value. VictoriaMetrics return different results from sum query and value counted from samples. Important note: it isn't recommended using Prometheus labels for storing potentially unbound number of unique Transform range vector which contains absolute messages_in_total to a range vector with which has a value for each second. 1. Prometheus stops returning time series if the distance between the latest sample and the requested timestamp exceeds 5 minutes by default. Solutions. last_over_time() rollup function, which returns the last value per each time series on the given lookbehind window d in square brackets. I want to display the average duration per each query within the selected timeframe. This is because of data model quirks for increase() function in Prometheus - see this comment and this article for details. Follow edited Dec 15, 2017 at 16:35. First for each series we want to get the maximum value over the plot interval. Samples that are not native histograms are I want the query to return the most recent value. 5 Prometheus query to get the value of a metric since midnight or a dynamic offset. onr rpe rcjd etfyz ycsasfv chhjlep ytuz qxlj mzz dvstmin bzeplx xvvor iojf xxmoz dfaz
