Prometheus divide two metrics with different labels For example, the following query extracts the project. instance, queue). This causes prometheus alertmanager to potentially change the state of I see "prometheus" and "prometheus_replica" labels used in the queries on the prometheus that pulls metrics from federated endpoint. Does it make sense to keep two different versions of code? This query adds a empty metric with zero values. How to divide after grouping two different metrics in Prometheus? 10. I'm currently testing a script to scrape metrics and send to a prom file. How to aggregate based on one label value, but preserve the other label values? How to divide two Prometheus Counters. Every time series is uniquely identified by its metric name and labels. , same metric name with different labels), is it possible to aggregate these at scrape time into a single value, e. See these docs. 67. Prometheus metric relabel for value. Share. I don’t know the value of “id” beforehand, that is always automatically generated. what expression should I use to output two metrics in grafana from prometheus. 6. Join two prometheus queries. operations is a list of operations that were applied to the metric, newest operation The Prometheus data source plugin provides the following functions you can use in the Query input field. My situation is this: I am using Prometheus with Grafana, and with a graph, want to sum() my metrics in groups based on what their value of the label "mylabel" is. For example: metric1 has label instance with time series (a, b) metric2 has label instance with time series (b, c) I want metric1 + metric2 so that I get: metric1{instance="a"} Joining seems to work with two different metrics but not the same metric or I can't figure out the syntax. Let’s say we use the excellent “node-exporter” project to monitor our The individual metrics are no problem to find but I cannot comprehend how I am going to AND the different metrics in one query, grouping them by a set of labels (ie. Additionally both rate and irate require at least two samples in range vector to return anything. I hope you can help with the following question. 4. . Sure, using a label_replace is absolutely appropriate. Prometheus regex match on different labels. sample-y from project. How to divide 2 metrics in Prometheus PromQL. How to subtract metrics with different labels? 1. Prometheus provides the following ways to divide time series with labels by time series without labels: How to divide after grouping two different metrics in Prometheus? Related. 1 How can I combine same name of prometheus time series with different labels into one metric? 0 How to Join two series in Prometheous using operator + I could create 2 metrics stock_price and stock_volume, or 1 metric with a label having values price and volume, but either way, when querying, these two series would need to be joined on the client using the timestamp as a key, I'm new to python and prometheus. For some metrics like kube_pod_container_resource_requests_cpu_cores or kube_pod_info my labels are not setted. I think there was a mistake in my understanding of how labeling in prometheus works. But other values of label name wouldn't be changed, I need to have this difference my_label - 2 for the whole table. com:10500 while icmp does not use the port so my. Closed MeenaAlfons opened this issue Sep 10 safer, and faster to Is it a good solution to use "label_replace" in a prometheus query when doing math operations on two metrics with different labels for the same value. I know there are 3rd-party panels that I can use (like singlestat So if you guarantee that in both metrics label volumename is unique, and present in both metrics at the same time, (with the same value of label volumename) and return result of division. Prometheus filtering based on Labels. Ratio between two (label,value) sets on the same metric #7922. if you declare two metrics with the same name, they should have the same labels and help text or the client will blow up (as it will have to expose the time series from both those metrics on the same /metrics page, with a single help string). For example: metric1 * on (ValueB) group_left(ValueC) metrics2 Here * is arbitrary operator and you can use any, depending on your expectation about values of resulting time series. If both metrics share common labels (like method), you can join them based on those labels: What Grafana version and what operating system are you using? v8. I’ve been banging my head against the wall for quite some time but haven’t found anything yet. Follow answered Mar 26, 2018 at 23:40. I am using the "MassTransit. This is the correct behaviour, NaN is what you want the result to be. For example, the following query selects all the series with names m1 and m2: {__name__=~"m1|m2"} So, the following query would select the max values over all the series with names m1 and m2 per each requested timestamp:. instance and pod labels change for these metrics when the job scales up and down. scrape_configs: - job_name: node_info static_configs: - targets: ['10. Labels are key-value pairs from every time series. Available metrics for the example. 0 * kube_pod_labels) so that it doesn't affect the result of first metric. Despite the fact I specified the metric name and most labels, Prometheus was looking for metrics that have the same set of labels. Combine label values from 2 different metrics: Grafana. In the wild, it's common for a Prometheus metric to carry multiple In order to compare two different metrics, you must write the query so that the same labels are also being compared For example there are 3 labels shown in this metric: group; Labels are very important in Prometheus. If you use http_3rdParty1_requests_total as the metric name you have putting two values, concatenated into one text field: the client name and the metric name are joined together. Histogram; import org I want to drop all the data fromistio_requests_total, which have specific label values like. Query prometheus In the wild, it's common for a Prometheus metric to carry multiple labels. In . I've managed to use two different metrics to the point where I can see how many pods for an However, in Prometheus, it's possible to enrich a metric with some static labels based on the producer's identity while recording it on the Prometheus node's side. One of the modules (call it "main") I am sending data related to two disks to prometheus. 1 Sum two aggregations with different results and keep all. Modules set it to UTC now after they've performed a successful "update" (whatever it means). 1:9100'] labels: machine_name: cool_machine_1 - Joining seems to work with two different metrics but not the same metric or I can't figure out the syntax. 17. Set Mode to Columns; Set Labels to be only the columns that are relevant so in this case it's So my_metric{job="job1", instances="2"} * label_values(my_metric{job="job1", instances="2"}, instance) might work, but I did not test it. 8. Implications of a Prometheus metric with different help texts? 2. treatment_length{"fileName"="file1"} 1000 treatment_length{"fileName"="file2"} 3000 and later you could use query. Asking for help, clarification, or responding to other answers. the query means:. Adding two values in Prometheus.

How to JOIN two different Prometheus metrics by label with PromQL. client. i. Say I have diskA and diskB and I am collecting disk_up metric. In the Prometheus Java client library there's a separation between defining label names (you do this only once, and it will create a "metric family") and observing a concrete event (this will create or update a "sample" within Use "labels per user". 0 [Prometheus][Grafana] Use label to map metrics between them. label; prometheus; grafana; division; arithmetic-expressions; or ask your own question. Each one of these metrics has two common labels device [mobile, desktop, other] I have a use case, where I wanted to exclude (filter) metric with particular label combination, I am using otel-collector for collection, processing and exporting metrics. Also notice, that here I showed two different approaches: simple replacement of a single value with another value for name. Labels. If you want to drop a label with a particular value from the collected metric, then use the following relabeling rule at metric_relabel_configs section of the needed scrape_config: - source_labels: You cannot. all independent metrics that match the regex above will show as a separate metric not all as one metric) – cgseller. Prometheus applies arithmetic operators such as /, -, +, * individually per each pair of time series with identical set of labels (ignoring metric name) on both sides of the operator. sample-y. My question is if there's a way to merge the zero vector with each metric values? Edit: I need grouping, at least for a user and name labels, so vector(0) is probably not the I'm trying to figure out how to add extra environment labels to all metrics in order to explicitly know from which cluster the metrics are coming from.

The syntax for division in Prometheus is straightforward but requires careful If you would like to keep all labels from the left, you can do that by adding group_left after the on / ignoring clause. So, I have the Here, we will use function label_join from Prometheus. For example, the following config would add machine_name label to the scraped metrics from the given statically defined targets:. istio_requests_total {reporter="source"} I have tried metric relabel configs, but they apply to all metrics and not just istio_requests_total. labels with the highest number of unique values at labelValueCountByLabelName stats; label=value pairs with the The metrics that are useless have label_one and label_two that do not match. 18. label_values(label) Returns a list of label values for the label in every metric. I edited my answer, seems like I misunderstood your question Querying prometheus label values with metric values. How to subtract metrics with different labels? 0. select time series with node_load1 name and with instance="host1" label and with instance="host2" label and with instance="host2" label. Use Is there a way to merge two different labels from two different metrics? So for e. In this case metrics on the left side of / have label {stat='misses'}, while metrics on the right side have different value for stat label: {stat='hits'}. The second rule sets name label value to an empty string (e. When two metrics have different sets of labels, joining them without properly handling the You can use the or binary operator in Prometheus. All the metrics is federated to a single different Prometheus where this problem is seen. 4. I have the numbers push to the same metric but use labels to identify where the metric came from.

Understand Prometheus Metrics Pulling. Modified 1 year, 11 months ago. This can be useful in Prometheus rule evaluations, since it lets you generate a new If it is not meaningful, split the data up into multiple metrics. Duplicate metrics in prometheus? 1. in Kubernetes we get container metrics with a pod_name label from cAdvisor and metrics with a pod label from kube-state-metrics. Here are Grafana transform functions you will need:. During querying via label_join() function: Prometheus divides one metric by another only if all the labels with their values for both metrics are identical. For example, given the following metric output 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 When querying a prometheus metric, I would like to group the sum and divide the grouped results on a second metric.

For example: If querying: avg_over_time(metric_1[5m]) From what I can tell, metrics in Prometheus need to be defined beforehand. If there is no activity during the specified time period, the rate() in the divider becomes 0 and the result of division becomes NaN. Ambiguous Prometheus metric value. All the best! Share. One metric (metric2) have always a result. level represents the aggregation level and labels of the rule output. left join prometheus metrics in grafana? 3. Commented May 8, 2020 at 11:26. Let’s take a sample Reading the code, feeding my local Prometheus playground with artificial metrics, running test queries, and validating assumptions, finally helped me understand how multiple Depending on the value of the label, I would like to divide it by a different number. I doubt that you have a scrape interval of less then 8 seconds. Typical examples of labels are: instance - an instance (a server or cronjob process) In the above example, there are four different time series. I have a metric (gauge) updated, which has module label that's set to a name of a module. inventory_quantities{sku="ABC", system="warehouse1"} value = 5 I have 2 different metrics : metric_a with a field type metric_b with a field type (same one) I'm trying to summarise a and b, of the same type. We need to display only the service_status where service_name is included in the label dependencies of module_status. 9. I'll suppose you have a recent Prometheus, install and that you can use sub-queries. Use the Division Operator: In PromQL, use the division operator (/) to divide the two metrics. How get difference between 2 different prometheus metrics? 0. Use label as metric in Grafana I want to take the min of a metric based on one label, but perserve the other labels so I can extract them later. I have two Prometheus metrics, and both of the metrics have an “id” label, and many other labels. 5. I would like to preserve the extra fields and have it apply to the full set and I need a solution that will work with ranged vectors so I can get data for several days/weeks. I want to count number of unique label values. Counters and Gauges allow for labels to be added to them. Prometheus the server doesn't care about help strings (or The Problem is that the instance Labels are slightly different: The Node exporter Runs on Port 10500, which leads to the Label my. Kind of like . ). I use ServiceMonitor with Prometheus operator on every kube cluster. 1 "Where" and "Join" in PomQL? 1. – michalrudko. Prometheus won't be able resolve it while the label names collide. Now, I would like to drop instance_type and instance_state only if the metric is foo. I'm currently trying to alert on Kubernetes pods stacking within an availability zone. Prometheus: PromQL - Adding a label to the metric. Do you mean you have a metric couneter_metrics with different labels that you want to sum? When do the splitting fields of two cubic polynomials coincide? Found the answer here How to divide after grouping two different metrics in Prometheus? The key is to ignore existing labels with / ignoring Add a comment | 3 . you can include extra info and use re-labelling to You would have to use the vector matching instruction which, in brief and in simple cases such as yours, translates to indicate which labels should match on both sides of the operator. Prometheus provides /api/v1/status/tsdb endpoint, which exposes metric names with the highest number of labels inside seriesCountByMetricName stats. As it was repeated numerous times, again and again rate must be applied before sum. 0 * kube_pod_labels ) so that it doesn't affect the result of first metric. What are you trying to achieve? I am performing a group by divide operation on selectors based on a label which we will call “name”. For example, having the capacity of various queues in one metric is good, while mixing the capacity of a queue with the current number of elements in the queue is not. You can use a query like this: Why is this important? Getting the ratio of two sets of (label,value) pairs for the same metric is common use case which can be implemented efficiently if it is natively supported by a function in prometheus. I read I should use metric_relabel_config but I don't understand how. How to subtract metrics with different labels? 3. The metric name is dropped. The following should provide a single metric vector giving you the time of the last creation (over the last 3h): I am trying to create a table/chart in Grafana showing the total number of unique users who have logged in to a given application over a given time range (e. Step 3: Using the on and ignoring Keywords 1. net core project. alertmanager_alerts_received_total or alertmanager_alerts_invalid_total Result: I have two metrics, Counters to be precise, lets say they are called NumberOfVisitors NumberOfLogins In grafana I would like to plot is the number-of-logins divided by the number of visitors (or I have my metrics exposed by Prometheus as: custom_metric{label1="abc", label2="xyz"} num1 custom_metric{label1="def", label2="uvw"} num2 custom_metric{label1=& Querying prometheus label values with metric values. Please note that you must use metric_relabel_configs instead of relabel_configs if you want apply relabeling on the collected metrics. Prometheus : how do i sum by with 2 different metrics Is it a good solution to use "label_replace" in a prometheus query when doing math operations on two metrics with different labels for the same value 1 promql regex with label_replace returns blank value when regex contain \w If you need to use labels as arguments for some arithmetic operations, you'd better expose them as separate metrics. In your case time series on the left side differ only by metric names, so PromQL sees series with identical sets of labels on the left side. The PromQL query would be the following: I have two metrics I want to add together, but not all the labels are present in the two metrics. For different services you should usually vary the job label, so I would suggest duplicating the scrape config with a job_name of service1 for one and service2 for the other. Look at the original answer: You can use + operator to join metrics. I have a metric, Hi, I am looking for a query or transformation to calculate the wait time between two metrics. As you can see, even though they are different metrics, they share the same set of labels [event_type, result] and we would like to create a panel in Grafana that shows both of them aggregated as if they were the very same metric, just grouping them by event_type and result, so we would have a dropdown selector filled with all different event Note that it may be a bad idea to put user into metric labels if the application is going to serve unlimited number of users. Grouping metrics with the same value to a label without knowing the label values with PromQL. I. If you designed a SQL database that way, e. now the entire goal of the graph I’m creating is to calculate and display the value of value(A)/value(B). Details: metric1 (component=“xyz”, activityEndTime=“epoch time1”) — created at 11/01/2021 09:47:00 AM metric1 (component=“abc”, activityEndTime=“epoch time2”) — created at 11/01/2021 09:52:00 AM Looking for the query either time difference between the metrics Imagine I have metrics like this: sample_metric{type="some-type1-1234"} 2 sample_metric{type="some-type1-5678"} 1 sample_metric{type="some-type2-9876"} 4 sample_metric Skip to main content Prometheus regex match on different labels. Here, group_left() will include the extra label: label_source from the right metric kube_pod_labels. Prometheus simply scrapes the metrics from KSM - this way Prometheus doesn't need to scrape the individual pods. In all other cases, I would like to keep the existing labels. Looking at the metrics, I can see that some of them have dynamic names, most probably delivered by dropwizard metrics. Say if my labels in prometheus are instance, cpu, mode for the query node_cpu_seconds_total, i want to do an operation like, Prometheus metric relabel for specific value. The lag for the first time How to aggregate two metrics metric1{ValueA=1, ValueB=2} metrics2(ValueB=2, ValueC=3} in PromQL where I want to have the following output? Difference between two metrics with time offset in PromQL. Step 1 : Used following query to get all metric names, query succeeded with all metric names.

Prometheus: filter query based on another metric. Division (/): Division is commonly used to calculate rates, ratios, or percentages. I have different metrices in prometheus counter_metrics a, couneter_metrices b and I want a singlestat for the count of all the different request metrics. Labels to fields This function separate the labels in the metric to columns. http_request_duration_seconds_bucket or http_request_duration_seconds_count Here is a demo working example using instance as a common label for two different metrics. It means when the label changes from 1 to 0 the time series with managed=1 becomes stale (not updated anymore), and series with managed=0 becomes active. instance. 03. 11 value stored in the index label and puts the extracted It calculates the difference of two metrics on every 10-second interval and then calculates the average over the differences for the last 5 minutes. g. prometheus. Provide details and share your research! But avoid . [Prometheus][Grafana] Use label to map metrics between them. The easiest approach to add labels to targets defined in static_configs section is to use labels section - see these docs. I want to treat the missing label values as zeros. Let us see the function usage, label_join(v instant-vector, dst_label string, separator string, src_label_1 string, src_label_2 string, ) v is instant time series; dst_label is This effectively removes all the labels other than instance from result and allows finding time series pairs with identical sets of labels on the left and the right side of How to divide two Prometheus Counters. Now I need to add some static labels to those metrics but could not find a suitable way to Here label_replace is applied tow times: one for each label. If you run just the query on the right side of the ‘*’ look to see which labels are provided. The label naming might not be 100% aligned, i. You need to use or operation for Joining two metrics in Prometheus is commonly achieved through the use of the * operator or the group function, If they have different labels, you might want to use the ignoring or on keywords. Grafana variable for all prometheus metrics with prefix. 5. Prometheus: detect creation of metrics (same name, different labels) 23. Using on. 1, I have obtained a way to construct a table like you have described with prometheus metric like that. I want to do a filter in prometheus based on all labels. The two metrics have similar but not identical labels since they are on different hosts, the job label value is different and the instance value is different So, we have to “ignore” those After some experimentations in Grafana 9. The solution is to copy metric names for left-hand side time series into another label before applying the / operator and then ignoring this label during the / operation. metric_to_keep{ label_one="identical-value", label_two="identical-value" } metric_to_drop{ label_one="different-value", label_two="value-is-different" } I thought I had a great solution by using this bit of regex: - source_labels: [label1, label2] action: drop regex If I query for the same metric but with a different label then I get a result 0: If we have two different metrics with the same dimensional labels, we can apply binary operators to them and elements on both sides with the same label set will get matched and propagated to the output. Is it possible? – hemu. In the case of the node exporter it would be: (<OutOfMemory expression>) AND ON(instance) (<HighCpuLoad expression>) From a usability point of view, I would rather have that should not use 0 count values in the division, and then re-introduce them has 0 via the or . 116 1 1 silver badge 2 2 bronze badges. mymetric{name: thing1, mylabel: a} mymetric{name: thing2, mylabel: b} mymetric{name: thing3, mylabel: a} How can we add extra label to Prometheus metrics? 1. If we are monitoring complex systems, we might get metrics on different connected entities from different metric providers. Add a I can obtain a label value os_name from two different metrics called here metric1 and metric2. Prometheus provides ignoring and on operations, which may be applied to any binary operator (i. The metric you're joining is forced to zero ( i. If "metric1" has label "labelA" with "A" and "B" values, and "metric2" also has label "labelA" but with "C" and "D" values, "metric1 + metric2" will return nothing. PromQL if/else like expression. e. before applying regex, string would be first split on separator (otherwise what is its purpose?), ; each substring has regex evaluated against it, ; if match groups are declared and found, they will be available as I want to be able to compare a given metric avg_over_time(metric_1[5m]) to determine whether this value is greater than the average of the other metric_1 that has some shared label. It is possible to use label_replace() function in order to extract the needed parts of the label into a separate label and then group by this label when summing the results. It selects time series matching the app_version{env="demo"}. See this article for details. Is there any documentation on how these labels get How Labels Enhance Prometheus Metrics. I have 2 metrics from 2 micro services. Any help would be appreciate. prometheus list labels for all metrics not having a label. Common use cases for relabeling include dropping high-cardinality labels or unnecessary metrics, improving readability by renaming labels or their values, and excluding specific targets from Recording rules should be of the general form level:metric:operations. /, +, -, etc. If it is not meaningful, split the data up into multiple metrics. Any metric test_gauge with label name set name_value will have it replaced with renamed_value. and operator on two metrics with one same label - promql. last 24 hours). In this case, the value of the right side will be applied on each of I have an application that has a lot of useless metrics that I want to weed out before scraping. Not only was the event label value different, but there was a corresponding difference in the terminal label value. metric is the metric name and should be unchanged other than stripping _total off counters when using rate() or irate(). Prometheus" NuGet package to add metrics to my Asp. I want to alert if metrics of one disk stops sending metrics. When joining metrics, these labels become the key to establishing I have two stat panels (let’s call them panel A and B) and each stat has different Prometheus query. Related. 1. SuperQ SuperQ. So most likely you range selector is incorrect, and you need something bigger like [30s] or anything, but at least twice The KSM collects all the metrics from all the pods across all the namespaces in the cluster. However, in this case, two metrics have different label values, so they can't match ! Is there a way to basically to do a join of the above labels using ifIndex to correlate to the the ifDesc label? Or maybe the job can be used to tie the two timeseries together? I have looked at the group_left feature but haven't been able to figure out how to get it working to combine/aggregate labels. paid_visitors which is a counter that is incremented when a paid visitor enters the website and stays for at least 5 minutes. There are two metrics, one returns 100 as value and the second 200. 18 Prometheus : how do i sum by with 2 different metrics. Given a metrics with various labels (i. Follow answered Jan 13 at 9:12. But when I try to get a maximum by app, prometheus does not calculate the difference anymore because the two metrics have different labels: Expression max total offset 30s - max by (app) (current) Output {} (nothing) And that is because the result of the individual calculations have different labels: How would I join metrics by their similar labels and calculate the difference? Example I have metric for tracking the inventory from two systems. This may result in e. 1. Normal relabelling can be only used to work on labels of a target after service discovery, which are generally meta labels starting with __. Prometheus performs the app_version{env="demo"} != app_version{env="live"} query in the following way:. Without a solid understanding of the matching rules, I Possible duplicate of How can I 'join' two metrics in a Prometheus query?. I would like to display these two values in one line in grafana graph. high cardinality issues. This way you have values split by results, and if you need aggregation for total call, For example, when I needed to match multiple metrics using the common labels, I quickly found myself reading the code implementing binary operations on vectors. however when I try to write a config it remove/exculde/fiter that metric completely with other label combination set. Once metrics are joined in Prometheus using label matching techniques (like on, ignoring, group_left, or group_right), you can apply various mathematical operations to analyze the data and derive I like to break these down. PS: my config already have this: How can we add extra label to Prometheus metrics? The lag function is calculated independently per each time series returned from the given series_selector. Do not put multiple unrelated concerns into the metric name. One of them do add(+-1), other do set true absolute value each hour. The other metric (metric1) is sometime empty but when it is not, it's always the good value. Labels are not supposed to be used in this way, and there are no ways of combination labels and metric values. Use label as metric in Grafana Prometheus source. Prometheus : how do i sum by with 2 different metrics. This is one occasion where label_replace is very handy! There is a different approach for getting CPU count which is quite common. When pods are deployed, their deployment has certain pod-related labels as shown below. All these time series have the name In order to compare two different metrics, you must write the query so that the same labels are also being compared For example there are 3 labels shown in this metric: group ignoring worked once someone pointed out that there was more than 1 difference between the label values. It also exposes other useful stats, which may help determining the source of high cardinality:. So, this can be @Oliver These metrics are collected through a kube-state-metrics job. Is there any way to define them dynamically at runtime instead? Is the idea that I'd be able to have multiple copies of the total_volume_capacity metric, each just with different labels? for example: total_volume_capacity{name:"volume1"}, total_volume_capacity{name Unfortunately, it is not possible to change the labels on old metrics in Prometheus.
