Promql sort by value Understanding these data types is crucial for writing effective queries and avoiding common pitfalls. How to combine separate timeseries labels in Prometheus query? 29. In the Prometheus UI, the "Table" tab is for instant queries and the "Graph" tab is for range queries. Is that doable? Thank you! voranilamj December 14, 2023, grafana, promql, grafana-templating. Hi, I’m new in PromQL. At the core of Prometheus lies PromQL (Prometheus Query Language), a powerful and flexible query language used to extract valuable insights from the collected metrics. For example: I want to explore the possibilities of capturing any sort of partial consumer group failures due to any reason using PromQL in Prometheus. Label manipulation allows you to work with time series based on specific labels or even modify them to perform more refined queries. "1472884" <== Value ] } ] } } But in the graph view, I can see the graph like following. I would now like to take a range of the sort() orders rows in each input table based on values in specified columns. So you need to combine the results of two PromQL queries into one, f. Quick Reference: Essential PromQL Syntax and Operators I would like to access another field’s value, but I can’t find a way to achieve this; I can only access the field’s name (which in this case, after the ‘Reduce’ transform, Grafana sort by labels with prometheus datasource. See more PromQL sort by value is a function that allows you to sort the results of a PromQL query by the value of a specific metric. Stack Overflow. However, by using sort_by_label, the user essentially tells us they aren't interested in the sample value, but in label values. Looking to have something like. sort # sort(q) is a transform function, which sorts series in ascending order by the last point in every time series returned by q. This can be useful for identifying the top or bottom values of a Use sort_by_label and sort_by_label_desc functions. 8. abs(v instant-vector)returns the input vector with all sample values converted totheir absolute value. sort_desc # sort_desc(q) is a transform function, which sorts series in descending order by the last point in every time series returned by q. @torkelo Right now Transform is unable to sort by value; are you saying that Transform should support sorting by value in the future? We were hoping that using sort or sort_desc in our PromQL would result in a sorted bar gauge in Grafana, which we can see if we toggle Instant as others have mentioned, How to calculate the average value in a Prometheus query from Grafana. One output table is produced for each input table. How to merge zero values (vector(0) with metric values in PromQL. 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. lookback-delta command-line flag. Select latest sample for series with a given metric name: Filtering series by value. In Is is possible in PromQL to query a label with a list of values? For example this is a how you’d do it in SQL: SELECT * FROM my_table WHERE column_1 IN ('A', 'B', If you set a Custom all value of . : levels{set_id=1, instance_id=1} = 1 levels{set_id=1, instance_id=2} = 2 levels_expected{set_id= 1} = 2 levels{set_id=2, instance_id=1} = 2 levels{set_id=2, @ManjuN (. Viewed 8k times Now, I enable "multi-value" and "all values" (with ". Dashboards. For general documentation on querying data sources in Grafana, See Time series kind formats for information on time series data frames and how time and value fields are structured. How to ignore missing datapoints in PromQL query? 29. Working with Timestamp Metrics. Expression Node Types. I have a Grafana graph where I'd like to show the results from a PromQL query with a conditional value being factored in. @ivanahuckova, Thank You very much for the https://play. I've a Prometheus query asterisk_endpoints_state returning multiples vectors, here's an example of the labels, plus the current status value, either 0 or 1 asterisk_endpoints_state{eid="xx:yy:zz:0 Difference between PromQL "by" and "without" unclear. Ask Question Asked 1 year, 11 months ago. The or operator is substituted with and operator and the rate({code="2xx"} is put in the front of the query, since a and b returns a when there is a matching time series with the same set of labels at b . grafana define variable with prometheus query based on metrics. Prometheus query to Filter prometheus results by metric value, not by label value. promql, changes() shows how many times the metric value has changed during the interval, while division by 2 is to compensate the state change back to normal. Related topics Topic Replies It seems that the value of 1 falls into the top 10. Now that we understand the data structure, let’s explore PromQL. sample-y. If I enable prometheus at the bottom in blue all the data is correct but the instance order messes up, if I turn it off they are all in order. Detecting Absent Series For ex: node_value metrics with 10minutes of data node_value{ID="1",instance="xx. topk(1, sys_cpu_host_seconds_total{mode="sys"} or sys_cpu_host_seconds_total{mode="user"} ) Note that topk(k, q) query can return more than k time series when this query is used for building a graph in Grafana. But using using avg_over_time directly on the metric won't work. And sorting by labels value is supported by functions sort_by_label and sort_by_label_desc. ”}[7d])) by (container))” against Prometheus DS using Bar Gauge graph, for some reason even if Prometheus returns the querry in inspector or in it’s own search instant, Grafana starts loading simple replacement of a single value with another value for name. Label Filtering Grafana multi-value variables and PromQL query label filter. When put in a Grafana dashboard in a single value panel, this doesn't display the version string but instead the count value (1). sample-y from project. 2. 128. My approach was to get the min value over time, as if the time series had a single 0 value within the 20 minute window it would report as a 0. If time series on the left and the right sides of / contain distinct sets of labels, then on() and group_left() modifiers may help:. Introduction to PromQL. , Value-Based Filtering: Triggers alerts based on specific metric values, reducing false positives and enhancing the effectiveness of monitoring. *"}) but of course, this doesn't work as labels are strings. . 6k 3 3 gold badges 47 47 silver badges 72 72 bronze badges.

Functions and Operators. 7. The result of this is an instant vector which I now want to filter by using a simple > 0. 0 Why time duration needs double dot for Prometheus but not for Victoria metrics. 13. it doesn’t sort the data from lowest to highest. By default Prometheus performs division over pairs of time series with identical sets of labels on the left and the right side of / according to these docs. For example, the following query extracts the project. $1 is then filled in by the value found in the parantheses (). Expected output: Value 10. Understanding PromQL queries starts with understanding their basic components: 1. filtered by value == 1. PromQL comes with a variety of built-in functions to help users analyze metrics. Set Operations. See matching rules for binary operators in Prometheus . 5. To filter Prometheus results by metric value, use PromQL (Prometheus Query Language) with comparison operators. Output data. Currently, if sort_by_label encounters the same label values to sort by, it falls back to sorting by sample value. * in your variable it may help performance if you have a long list of values. I tried MIN(metric1, metric2, metric3), MIN([metric1, metric2, metric3]), etc. How to get metric labels values from VictoriaMetrics. Query to show label values in Grafana (using prometheus) 10. Comparing to Past Data for Simple Anomaly In this section, we will learn how to sort the query results, or select only a largest or smallest value in a set of sequences.

Labels in Prometheus are crucial for organizing and querying Is there a way to get the label values as the Value of a prometheus query. Lets say I have some metric metric and I perform a selection over a dimension by doing metric{ dim = "some value" }. sort() Yeah my bad I forgot to remove the sort function haha. What I want, however, is to do a replacement treating the value of the label as a scalar. Labels: Key-value pairs that add dimensions to metrics. Prometheus: how to get label_value() in query. grafana. Metrics: Named measurements collected at regular intervals. Using sum_over_time for a Promql increase function recorded using recording rules. Selectors, with a metric name and label matchers. Sorting by value is supported by functions sort and sort_desc. Is it possible to use the increase() function without a label in PromQL? 1. I tried exploring the label_replace function to create a new label out of the metric value but no go. 34. So the usage label must be put into time series value instead. The Bar Gauge view is now always sorting the metrics alphabetically. An overview of PromQL features . For example, http_requests_total{status="200"}. Label filtering allows you to select time series that match specific label values. Labels: These are key-value Is there any way to change the order of Grafana panel stacked series that come from the same PromQL query? This is very easy when there are multiple queries (just drag and drop up or down), but I don’t know how to do it It isn't recommended to put frequently changed values into labels, because this may result in high cardinality issues. These ones sort by value, ascending or descending: sort (node_filesystem_free_bytes) sort_desc (node_filesystem_free_bytes) topk (3, node_filesystem_free_bytes) The last one sorts by value and gives only the top 3 values. Note that the step value after the colon (50s in the example above) Promql: Is it possible to get total count in Query_Range. on a refreshing dashboard) and would consist simply in recording the value of count_values without() ("value", up) into a new metric and then calculating sum_over_time() / avg_over_time() on top of that metric instead. How to filter using Grafana queries. Working with Histograms. As SkyWalking and Prometheus have fundamental differences in metrics classification, format, storage, etc. Prometheus I would like to have a graph of the min value while preserving the label to inform the user which label2 currently has the lowest value. 123. Expression Result Types. It shows some longtail api requests like /admin/phpMyAdmin all. This is because topk(k, q) independently selects top k series per each I am writing this detailed explanation to illustrate what people often mean by "I can easily sort a dictionary by key, but how do I sort by value" - and I think the original post was trying to address such an issue. Say I have diskA and diskB and I am collecting disk_up metric. Query Types and Overview. Using the “Sort By” transformation doesn’t work in this case since there is no field I can select to sort by. Next, we need to sort by time, otherwise the state timeline will get confused. 15.

For example, i need to filter out the instances which has more than 80 % CPU usage. PromQL works exactly the same in each cases; the range query is just like an instant query run multiple times at different timestamps. PromQL: Access metric for instance while grouping by instance. Join two prometheus queries. Prometheus query to count unique labels over a I have this table in Grafana and the data is perfect but I can get it to sort by instance name, if fact I'm not sure what method it's using to sort. Step-by-Step Guide: Filtering Prometheus Results by Metric Value. 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. By now, you know what PromQL is and what you can achieve when executing well-written queries. I have lots of VMs, almost 300. You need to use or operation for I have 2 metrics: levels{set_id, instance_id} levels_expected{set_id} I need to group both by set_id and count all sets, where all instance_id values of levels equals levels_expected value. brian-brazil brian How to filter label name after count_values in promql. We can usesort()(Ascending) orsort_desc() I want the query to return the most recent value. I got an idea while thinking about #12503:. Group by measure values returned by aggregation. This function is supported by PromQL. I was Cell display mode to a value of LCD Gauge. For that we are going to leverage the @ end() modifier that allows to take the value of the last evaluation interval. I was wondering whether I can sort the results based on the metric result? Or if there is a Hi, I am using Grafana and InfluxDB to analyse my home automation setup, and have used the Bar Gauge in a few places already. Prometheus grouping by label. Using label value of metric as value on grafana. With a time range equal to the step, one input value (i. ) To make up for the data it throws away, Prometheus uses extrapolation to adjust the result of the calculation. As already mentioned this doesn’t change if I am additionally trying to sort in the select statement or the input database is already sorted. In my instance I am interested if a metric has had the value 1 for a period of 20 minutes. Modified 1 year, 11 months ago. I am sending data related to two disks to prometheus. By default Prometheus returns the most recent values if they were posted during the last 5 minutes. Any value of test_label will be modified. 28. You can see the format of my query and data in the pictures below. Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question. 1. PromQL (Prometheus Query Language) is a functional query language provided by Prometheus to enable the user to query data stored in real time and perform all sorts of analysis, aggregations, and operations. Ideally all the labels must be static. Third-party systems or visualization platforms that already support PromQL (such as Grafana), could obtain metrics through PromQL Service. When building PromQL queries, a frequent need for users is to get an idea of the data they are working with, and a way to explore the space of all available metrics and their labels. I wanted to add this additional info in the String: A simple string value (currently unused in PromQL). I need to sort these all panels by their value. 1 on Google GKE What are you trying to achieve?

I configured the legend to be a table and I try to click on the min/max headers (the metric names column does not have a header, First we convert all the labels (name, state) into fields, leaving us with (Time, name, state, Value) Next, we merge all frames into one (the L2F transformation does something weird with the frame names) Next, we need to drop the Value field. Let's explore some of the most commonly used ones: Rate and This should be implemented as a sort transform using new transform feature. In this guide, we will explore the basics of PromQL and provide query Every so often, the most straightforward way to show some information in a Grafana dashboard is with a table, for example to list how long it is before TLS certificates expire, how frequently people are using your VPN servers, or how much disk space they're using. The average has to be grouped by each ipaddr. I wanna know how to query metrics with promql; or ask your own question. Below are some examples of PromQL queries that use gauge metrics. Here's how: You should use topk for selecting the metric with the maximum value:. 11 value stored in the index label and puts the extracted 1. Share. – rachitchauhan43 changed the title P99 created using histogram_quantile shows value greater than the maximum possible value in the series BUG: P99 created using histogram_quantile shows value greater than the maximum possible If there are 100 million requests per minute, do we really need to store and sort these 100 million requests in the monitoring system to calculate the percentile value? That would be too expensive. (See Prometheus issues #3746 and 3806 for A LOT more detail. Select largest label value in Prometheus query. thanks for your suggestion regex101 it’s a great site, I use it too but maybe I explained myself badly also because I reply to these posts late at night and many times I’m tired, by the way, my problem wasn’t so much finding a pattern for the match but it was how I then had to insert it in the transformations in the grafana panel to change the sorting Hello all, I am plotting a bar gauge with several measures, and would like to sort it by value (at the moment it seems to be sorted by name). Prometheus - Aggregate and relabel by regex. To understand it in detail, i like to enter it into regex101. It's not from a specific task but I was just curious to see if that is achievable while learning PromQL. In such case, how can I find out the average of the metric over 24 hrs for each Master PromQL, advanced techniques, and best practices for efficient metric analysis. Output tables have the same schema as their corresponding input tables. Group labels in a Prometheus query based on regex. How to use promql group You can notice that here we have labels allowing us to have a match between an instance IP address (10. 6. First for each series we want to get the maximum value over the plot interval. Prometheus table only uses the last value for each serie. 21. To start with, the basic syntax of PromQL follows the general form of Google's Re2 (re ~ regular expressions prometheus-promql query based on label value. How can I group these by value and return a count. PromQL "topk" function is not working as expected. We don't need it. I want to alert if metrics of one disk stops sending metrics. Mainly for display reasons (tabular view), it would be sometimes useful to not sort by the value of timeseries, but by a given label value. FunctionCall is the type of a PromQL function implementation vals is a list of the evaluated arguments for the function call. PromQL - how combine "sum_over_time" with "by" 0.

The lookbehind window can be augmented on a per-query basis via last_over_time() function. How can I create a query in PromQL so that it displays all the metrics that contain the xxx label? 1. PromQL/MetricsQL if value in range divide by constant value or map function. PROMQL sort. Thresholds and Filtering by Value. First you want an aggregator with a result per value of a, and then you can count them. The query is simple, similar to this: node_cpu_seconds_total / 4. The PromQL query always works based on the (event_gauge{success_or_failure="success"}[1h]) / count_over_time(event_gauge{success_or_failure="success"}[1h]) to sort of get what you Instant vector: A set of time series, each with a single value at a specific timestamp (e. With count and sum I can't see those Grouping metrics with the same value to a label without knowing the label values with PromQL. How can I construct a Prometheus query That doesn't work. Hot Network Questions Proposal I got an idea while thinking about #12503 : Currently, if sort_by_label encounters the same label values to sort by, it falls back to sorting by sample value. PromQL provides a rich set of functions and operators to manipulate and analyze time series data. Monitoring data is sampled I am sending Metrics to Prometheus and I am able to visualize their values using PromQL in Grafana. 1+0. What I understand here is create the "duration per second" (rate sum / rate count) value for sort_desc(sum(rate(my_call_count[1h])*3600) by (tenant)) But it doesn't work as expected when the above query is used in the grafana table. Jan Garaj. In this section, we will take you through the features that PromQL has. It describes what the series represents, like http_requests_total or node_cpu_seconds_total. But other values of label name wouldn't be changed, addition of the renamed_ to all values of label test_label. Ignore specific set of labels on prometheus query.

While the UI tooling for this is still evolving (PromLens and Grafana both have some data exploration features), you can also map out your data using PromQL queries. The thing I wanted to try is to get a range-vector with records over that time range and with value equals to 1, i. Now, grouping is not allowed in avg_over_time. Prometheus / Grafana highest value and time. Related. Mastering PromQL empowers you to extract maximum value from your Prometheus deployment. 3. asked by Julian on 12:24PM - 07 Aug 19 UTC. In the original query the set of labels weren't identical, because they differ by code label value. Examples prometheus-promql query based on label value. PromQL join two metrics with identic label names but different label values. Provide details and share your research! But avoid . The data displayed on grafana table is correct, but the order isn't expected. For range vectors it will be a Matrix with one series, instant vectors a Vector, scalars a Vector with one series prometheus-promql query based on label value. My goal ultimately is to have the following in Grafana. I'd like to thank @markalex for his very intuitive and informative answer regarding my previous question as I thought it might solve my issue - and it does the way the question was initially stated - but for simplicity, I left out the fact that I have two different hosts and was trying to also separate by their cores in the same query. E. However, I need those missing values in my metric values, therefore I added to my prom query or vector(0). Prometheus topk returns more results than How to sort by label name in Grafana. It means I can query data with timestamp that prometheus. There is a specific ipaddr label. Understanding PromQL Syntax. Now you can run the below expression on your expression browser . As for the PromQL, with the help of Grafana Slack members I have recently learned that Loki’s Prometheus endpoint (localhost:3100/loki) uses LogQL, not PromQL. g http_requests_total). The right way to combine metrics in PromQL is vector matching, that might be one-to-one or many-to-one depending on labels matching. com – How do we filter one metric using label of another in Promql. 67. To finish off this PromQL tutorial, let’s see how PromQL can be used to create graphs of CPU-utilisation in a Kubernetes application. 0: 493: October 9, 2023 PromQL is defined in great detail in the documentation, so we won’t go too deep here, but briefly a query is built up from:. 3] I am trying to label gauge bar items using properties from the data table, after having applied the "sort I am trying to do this using the Override > Fields returned by query > Standard options > Display name option. multiple values from grafana variable in prometheus query. This lookbehind window is known as lookback delta and it can be configured with --query. Sort. Improve this question. Interpolating missing Prometheus values in a query. See these docs for details on how Prometheus calculates the returned Using PromQL’s predict_linear function leads to smarter, less noisy alerts that don’t give false alarms and do give you plenty of time to act. - prometheus/prometheus It seems like the promql I did gets the 95th percentile of the linear data. As the title says, I am looking for a way to get the maximum value of a time series, You need another sort transform to get the rows back in order. I am trying to combine 2 metrics in a promQL query using the Grafana example here: https: Grafana / PromQL query to chart a value per hour in a bar chart. I want to determine the minimum of the current values of those three metrics, and I can't figure out the PromQL. How to execute a query with two metrics in Prometheus? 0. sum by(pod) (rate(container_network_receive_bytes_total 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=~". 0. I started with a bar gauge that was labelled correctly, with mean data, but the items Vector matching. Comparing to Past Data for Simple Anomaly Detection. Here's an example: topk(1, package_class_method_mean{domain="my_domain", asset="my_asset"}) Now, this shows me the graphs fine. each VM has prometheus label named “team” (1) I add each team’s VMs cpu usage(team A, team B, team C, ) Now for the actual PromQL experience. For example, the following MetricsQL query returns the percentage of disk_usage value comparing to the value stored at soft_quotaGB label: disk_usage / label_value(disk_usage, "soft_quotaGB") But looks like regex can only be applied on a label value and Not on a metric value. I'm using flexlm_exporter to export my license usage to Prometheus and from Prometheus to custom service (Not Grafana). Before setting up alerts, it’s crucial to have a good understanding of the core components of PromQL syntax. org tip, I did not know it existed!. Follow edited Feb 1, 2023 at 22:38. I think this should resolve by itself when you have more data. 2. PromQL Functions. And these are the values I get by the variable: Interface GigabitEthernet1/0/1 Interface GigabitEthernet1/0/10 . I what field do you put Proposal. MIN(metric1) works; it returns the current value of metric1. We will start with an explanation of the data types, and then we will look at how to select data, how to work on multiple datasets, and how to use functions. Range vector: A set of time series, each with a range of data points over a specified time duration (e. In SQL, this would be: With PromQL, this does not work: count by (stage) ((max by (instance) (stage))) How do I reference max stage in the outer aggregation? promql; Share. This works for getting max value with grouping the data by "Api" field. Anyone have an idea ? Note that the /api/v1/query_range returns calculated results instead of raw samples stored in the database. In this guide, we Join the values of two labels with a -separator into a new endpoint label: label_join(rate(demo_api_request_duration_seconds_count[5m]), "endpoint", " ", "method", Prometheus doesn't provide the ability to sort time series by labels and to select the first time series after that. the query means:. PromQL: time from last value of a series. So what are my options to filter by label value if I want to use the greater than operator? But the problem here is sort order. For example, the following query: last_over_time(application_version{site="NYC", instance="Test", id!=""}[1h]) Returns the following item I need to query a metric and find out the average value of the metric over a period of 24hrs. Additionally information: prometheus-promql query based on label value. I am trying to create a query that groups the data by "Api" field and selects a value field by using prometheus and grafana. In this section, we will learn how to sort the query results, or select only a largest or smallest value in a set of sequences.

Interface GigabitEthernet1/0/19 Interface GigabitEthernet1/0/2 I want to sort it but Numerical ascending sort didn’t really help. I guess it would be more useful to use the rest of the metric (label values, name) This type of query is for the most part just useful for "metadata" metrics which report a value of 0 or 1. It is used as a primary query language in VictoriaMetrics, time series database and monitoring solution. Ex. What Grafana version and what operating system are you using? 8. Get value of other label while applying filter on one label in PromQL. Prometheus query to count unique label values. In this chapter, we will provide hands-on steps to the FunctionCall is the type of a PromQL function implementation vals is a list of the evaluated arguments for the function call. For example, the following query sorts time series returned by query by metric names: sort_by_label(query, "__name__") Try to use query_result(sum(health_check_status{observe="yes"}) by (system)) and sort numeric (descending). 11.
