Prometheus relabel regex example. It will split a string like foo.

Prometheus relabel regex example relabel Examples of Dropping Metrics in Prometheus a. In this video, I explain the concept of relabeling in Prometheus, a powerful tool for filtering and transforming your flows of labeled objects in the Prometh. coreos To configure Prometheus to use different scrape URLs for each target, you can leverage the relabel_configs section in your prometheus. When first learning about relabel configs in Prometheus you will encounter many examples that looks something like this: relabel에 대해 조사하면서 알게 된 것이 하나 있다. You get metrics with exported_ prefix if the collected data already have one of the predefined labels. 我们知道prometheus是一个时间序列数据库。会周期性的从各个target上抓取数据。那么我们抓取回来的各种指标数据，我们有没有办法再次进行处理呢？ 比如： action: keep and regex: true ensures that metrics will be scraped from the pod only if the annotation prometheus. If there is a match, the object is kept. 1 min read | by Jordi Prats. For example, when measuring HTTP latency, we might use labels to record the HTTP method and status returned, which endpoint was called, and which server was responsible for the request. In the relabel documentation it shows that target_label is a <label_name> which is then defined here as a string matching the regex: [a-zA-Z_][a-zA-Z0-9_]*. relabel_configs: - source_labels: [__meta_kubernetes_namespace, __meta_kubernetes_service_name, __meta_kubernetes_endpoint_port_name] action: keep regex: default;kubernetes;https # Scrape config for nodes (kubelet). Relabeling/Keeping in Prometheus. What could be causing this? I would expect prometheus to either keep metrics from all nodes or drop metrics from all nodes. Hot Network Questions The problem is that relabel_configs contain relabel configurations that should be applied before scraping. Afterwards press Apply & Restart. Say for example, you have a label my_label and you’d like to relabel all the label values to custom_value where it contains 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. Locate the scrape_configs section for the job you want to relabel. source_labels: we’re utilizing the label __name__ to get the desired metric, since this itself is a label which has value of metric name. While the command-line flags configure immutable system parameters (such as storage locations, amount of data to keep on disk and in memory, etc. *' replacement: '$1' This Component(s) processor/transform. ec2_sd_configs: - region: us-east-1 access_key: access secret_key: mysecret profile: profile filters: - name: Imagine situation if you decide to relabel metrics for single target, using file_sd it is impossible without hacks and overcomplicating things. +" The relabel_configs option in Prometheus allows you to manipulate labels before they are stored. Relabeling instance name in prometheus. apiVersion: monitoring. To review, open the file in an editor that reveals hidden Unicode characters. *):. ; It then copies the values of matching label names to a set of new label names that are determined by To do this, configure remote-write with the write_relabel_configs parameter with a subparameter action value of keep or deny. But the parameter is not written/kept as label. Control Prometheus metrics usage from a Kubernetes cluster with specific methods. Using regexp with groups in Grafana. The example above suggests that Prometheus instances can be scraped by other Prometheus instances, but there are also several other ways to stack Prometheus and Prometheus-like instances. (The most notable such feature is backreferences. Two web search results (referenced below) hinted on using regexes to pass more than one parameter for each target. It prevents monitoring tasks that should be shut down. Hot Network Questions Is there a simpler proof for this simple geometrical result? (An equilateral triangle contains three congruent I have some k8S cluster (mon, foundation. In order to apply the label to any metrics scraped using a particular job we'll have to add a match for something that always exists, such as __address__. Have you tried to use discovery. You signed out in another tab or window. Without labels, this metric would only show the total number of HTTP requests. It is automatically anchored, so it must match the whole label name. *" target_label: "name" Note that the regex is defined with a string here, not a regex literal, so the first / is erroneous here. __address__ replacement: 'example. There are reasons why I can't change these, so I need to do some relabeling. From the documentation: drop: Drop targets for which regex matches the concatenated source_labels. In this guide I help demystify the often misunderstood relabel_configs and metric_relabel_configs in Prometheus to better monitor your website and APIs. prometheus_relabel_metrics_processed (counter): Total number of metrics processed. Say if my labels in prometheus are instance, cpu, mode for the query node_cpu_seconds_total, i want to do an operation like, input = ". Relabel用来重写target的标签 scrape_configs: - - job_name: "cephs" relabel_configs: - regex: job action: labeldrop image. This example selects only those time series with the http_requests_total metric name that also have the job label set to prometheus and their group label set to canary: http_requests_total{job="prometheus",group="canary"} It is also possible to negatively match a label value, or to match label values against regular expressions. yml file. 3 prometheus relabel_config drop action not working. My targets have an obscure target url like test1. For example, you can change __address__, so that Prometheus will contact some another host instead of that given by service discovery. You switched accounts on another tab or window. yml like as. <regex>, <replacement>), example replace(foo, service, "[A-Z]", "[a-z]"). There is a slightly more elegant way of doing this, that doesn't involve manipulating the address. Each of them have labels that can be used to compare them, but the labels are called different things on each. *) target_label: __address__ replacement: [__address__]:${1} EDIT: The following seems to work: 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 Prometheus is written in Go and uses RE2 and that does not support negative lookahead. mysite. com:. relabel은 의외로 프로메테우스에서 중요한 부분을 차지하는 것 같은데, 공식 문서에서는 relabel과 Meta Label의 자세한 사용 방법에 대해 일언반구도 없다는 것이다. *” at the end of your regex. We do a thorough break down of these powerful configuration blocks with The name of the label to drop must be specified as a regular expression in regex. Add . ; replacement: This determines what the new value of the target label will be. The rest of the lab walks through many more relabeling actions with examples for aggregation, dropping labels, dropping objects, mapping, upper case and lower case. But writing the regex to match everything but node_systemd_unit_state will be a PITA and the whole process will probably not be all that efficient. - role: pod metric_relabel_configs: - source_labels The Prometheus monitoring system and time series database. bar. Prometheus (metric) relabel config with inverse regex match / negative lookahead. alloy file to tell Alloy which metrics you want to scrape, how you want to process that data, and where you want the data sent. Unmatched metrics won't be sent. First of all, we are using Prometheus' relabelling future We must take a values for labels (in regex) in "()" to be compatible with RE2 rules. relabel component that has a single rule. - source_labels: [__meta_dockerswarm_service_label_prometheus_job] regex: .

The name of the label to drop must be specified as a regular expression in regex. Ask Question Asked 1 year ago. You can place all the logic in the targets section using some separator - I used @ and then process it with regex. In this example, you'll only send the metrics that match the regular expression. So as a simple rule of thumb: relabel_config happens before the scrape, metric_relabel_configs happens after the scrape. Relabeling rules: - source_labels: [__address__] source_labels: [__address__] It tests whether the regular expression in regex matches the concatenated string from the previous step. How do I configure prometheus (currently using the coreos operator if that matters), to keep only app=foo and drop the label baz, so that I end up with: some_metric{app="foo"} For what it's worth, here's what I currently have and the labels are showing up as is: - action: keep sourceLabels: ["app"] regex: "foo" - action: labeldrop regex: "baz" Proposal. For example, the following query extracts the project. How does one replace ports received from Consul to something else? I know this is possible with Prometheus relabel_configs but I've yet to successfully configure it. local The instance identifier can either be a word or two words with underscores or a word and a number with an underscore Using regular expressions in Prometheus relabel_configs source_labels. We have a lot of servers and those servers are all in a datacenter, are in a datacenter area and have a function. source_labels: This specifies the labels from which to derive new values. The modulus field contains the modulus to take off a hash of the concatenated source_labels. The reason for that is, the main label __name__ will be generated post scraping. sample-y. I tried using the keep action (as I'd like to keep time series that do match this regular expression) but this also drops all other metrics that do not I want to do a filter in prometheus based on all labels. * and it will include all metrics. Prometheus automatically anchors regex, so you need to add an additional “. (At least it is accurate, as far as I can tell. Using regex to only return some of the Loki Label values. This example has one rule block, but you Using regular expressions in Prometheus relabel_configs source_labels. The following steps build on the config. A useful thing to do when using horizontal sharding of Prometheus instances. yml is. Prometheus grouping by label. yml. This is my configuration: - job_name: 'kafka' scrape_interval: 10s static_configs: - Prometheus regexes are anchored, so your regex doesn't match. com/blog/2022/03/21/how-relabeling-in-prometheus Labels are sets of key-value pairs that allow us to characterize and organize what’s actually being measured in a Prometheus metric. Defaults to "(. RE2 regexp's don't support backreferences: RE2 disallows PCRE features that cannot be implemented efficiently using automata. write_relabel_configs: # drop specific metrics from remote-write - source_labels: ['__name__'] regex: 'go_gc_. Add labels under the labels key for each target. I'd like to drop time series that have this label and do not match a regular expression. There's an example of that in my blog post and video, where the pods to be scraped for metrics for a specific job are annotated prometheus. So, in your case the regex should look like regex: ". Prometheus create label from metric label. Prometheus Relabel Config Example. I attach the following to my pod so the metrics are scraped. ) and more complicated variations with alphanumerical regex like [a-z]. This allows you to define specific scrape configurations per target. Load 7 more related questions Hello! For some reason it seems that prometheus is dropping cadvisor metrics for about half of our ~250 nodes. yml). P. A regex query in Grafana. # relabel_configsとの違いは、metric_relabel_configsの場合、 # source_labelsには、***_configsや***_sd_configsに用意されているメタタグでなく、 # メトリクス提供元が付与したラベル名を指定できること metric_relabel_configs: # 例 5 : これまでの例と同様です。 In Prometheus configuration, I'd like to relabel_configs so that the value of __address__ is the current value of address plus the port. This value is a special constant that’s replaced with the OS of the host Alloy is running on. remote_write: - url: https://prometheus-us-central1. The deployment is pretty straight-forward, and so is editing the rules, however I could not find my way when trying to relabel the exporters using static_configs when using Prometheus-operator. *" node_cpu_seconds_total{instance=~". Here's how: Open your Prometheus configuration file (usually prometheus. In a relabel_config, the regex field supports any valid RE2 regular expression (). Attempts such as the following do not work: relabel_configs: - source_labels: [node_exporter_port] regex: (. regex, replacement, action, labelmap 등이 함께 섞여 이해 I'm understand how to relabel a single label using regex, but don't know how to use a several source labels. hashmod - source_labels: - __tmp_hash regex: 0 action: keep. otherstuff, abc-def02. com:8080' # Scrape URL for example. io/scrape: "true". Dropping Metrics by Name The regular expression specifies which metrics to drop. You can do that by clicking on the little Docker whale in menu bar and then on Preferences->File Sharing->+. *abc. The regex should match the whole string, wchich is constructed from values of labels passed to source_labels list concatenated with the separator (by default it is set to ;). This regex defines three capture groups separated by periods, effectively splitting the id value into its components. * is not working within metrics_relabel_config. Please find below an example from other exporter (blackbox), but same logic applies for node exporter as well. relabel instead?. +/health". Regex queries in Prometheus enable powerful filtering and aggregation of metrics based on label names and values. *server"} To select all HTTP status codes except I'm monitoring kube-state-metrics pod metrics. So, when you exclude any metric this way it will not be stored in db, using this approach you can reduce disk usage and exclude all not necessary metrics. Example: relabel_configs: # This will ignore scraping targets from 'ignored_namespace_1', # 'ignored_namespace_2', and 'ignored_namespace_N'. all other relabeling actions work as before (including drop on drop and keep); if relabeling config has action: append => the label set is dropped if none of action: append is satisfied; this logic can be driven by adding temporary label I’m afraid that is not possible because dots . port=1234 It uses 1234 as the instance port but if I don't specify it, I would get 8080 as the value I would set on the label. md relabel顾名思义，就是标签重写，可以允许用户重写标签或者针对标签做一些过滤操作，Prometheus中的relabel有三种，应用范围和工作时段不一样，一定要区分 relabel_config Relabeling is a powerful tool to Using regular expressions in Prometheus relabel_configs source_labels. You can directly use the captured For example, a relabeling rule may keep or drop an object based on a regular expression match, may modify its labels, or may map a whole set of labels to another set. The problem with "use configuration mangement" is that a static list of all label regex (default ‘. Some of the metrics which the Node Exporters exports have a mountpoint label. *' or similar regex does not work. 11 value stored in the index label and puts the extracted Prometheus doesn't provide relabeling actions for replacing some chars in label values or label names. Grouping metrics with the same value to a label without knowing the label values with PromQL. regex to match part of a prometheus label. modulus: The modulus to take of the hash of the concatenated To remove any labels starting with info_ from scraped metrics, you could write a metric relabeling rule like this: action: labeldrop regex: info_. 1. ; target_label: This is the label you want to create or modify. It looks like Prometheus has no functionality for matching label values in different cases :( But this can be solved with label_uppercase and/or label_lowercase functions from MetricsQL. Thanks for sharing some performance data. i tried various combinations like (. We're going to add a Prometheusのrelabel configの挙動がドキュメントからだと良くわからなかったのと、すぐ忘れそうなので実際に試してみた結果をざっとメモっておく。. alloy file you created in the previous tutorial. net/api/prom/push A good use for this action is to use annotations applied to pods to ensure Prometheus only gets the correct metrics for a specific job. ; It keeps only those labels that match. relabel you can relabel the targets before they are scraped. The labeldrop action works like labelkeep, but drops a label rather than keeping it. On the other hand, if all 20 of your jobs have exactly the same relabeling config, you might consider using a single job and additional labels for distinction (I assume you distinct right now by job label): - job_name: unitedjod scheme: 'https' I'm trying the prometheus-operator for the first time, and still struggling with the differences for managing Prometheus through that. Relabeling in config So, the inner label_replace introduces a new label called type_group, whereas the outer label_replace replaces the values with the type pulled from the original label, with the help of regex. 0 — a version with many long-awaited additions and improvements. So if there are some expensive metrics you want to drop, or labels coming from the scrape itself (e. Replace. What did you see instead? Under which circumsta Hello, I am playing around with Prometheus. How can I use regex in the values to return instance that starts with, lets say, prod or qa or other labels? Is this possible without configuring relabeling?. * action: drop Learn about prometheus. The problem is that Consul reports these nodes with port 8300, which is not the port we use to monitor targets. I tried with relabeling in service monitor but it didnt work. The other metric is_active represents if something on that node is running. Now, i don't know which metric is coming from which job. g. You can use the following actions: drop - Drops metrics where regex matches the string extracted using the source_labels and separator. Ask Question Asked 6 years, 8 months ago. *" or mode=~". otherstuff and abc-def03. Suppose that the following is part of the yml file. Modified 11 months ago. Below are four example scrape configurations that allow you to define targets and monitor corresponding metrics: node relabel_configs: - action: labelmap regex: __meta For static targets defined in your Prometheus configuration, you can add labels directly in the static_configs section. Is there any straightforward way to do this? I have multiple source labels need to be replaced so the configuration file has multiple entries under metric_relabel_configs, but i can see only one entry under metric_relabel_configs from Prometheus UI which is the last entry in the configuration file, is this might be the reason other relabel not working – job and instance labels are somewhat special with Prometheus. What you actually need to use is metric_relabel_configs. Use cases: Drop unnecessary Is there no way to create a default config for all jobs? No, there is no such way. (. Prometheus (metric) relabel config with inverse regex match / negative lookahead The value against which a regular expression replace is performed, if the regular expression matches the extracted value. And if one doesn't work What did you do? Example config: - action: labeldrop regex: 'c(. *' action: 'drop' # keep only specific #The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. You can see the other available constants in the constants documentation. io/scrape: 'true' So now prometheus scrapes metrics from the pod only if prometheus. – kholis. Find or add a job for your target. sample-y from project. if target is, for example Configure Alloy. The relabeling rule can be simplified with if condition when using VictoriaMetrics - Prometheus-like monitoring solution I work on: - if: "{__name__=~'test_. Let’s create an instance of a see prometheus. promql regex with label_replace returns blank value when regex contain \w. Here's a basic example: [__address__] target_label: instance regex: '(. Prometheus - Aggregate and relabel by regex. But I struggle with the regex and regex replace stuff. Learn about how to relabel metrics and when to apply certain labels in Prometheus in this self-guided, hands on workshop. When I use the following configuration: metric_relabel_configs: - source_labels: [__name__] separator: ; regex: kube_pod_(status_phase|container_resource_requests_memory_bytes|container_resource_requests_cpu_cores|owner|labels|container_resource_limits_memory_bytes|container_resource_limits_cpu_cores) I want to set targetLabels in Service monitor like key value map so it appears in the Prometheus metrics. label with regex- Prometheus. Using a standard I found out that Prometheus now has a labelmap option for relabel_configs that does this : https://grafana. Then Prometheus drops labels with empty values after the relabeling. You can have a label with your target that can be the source of your "relabel" action, something like this: 一、背景. the log file corresponds to the output of the regex . I need to match URLs based on specific conditions and relabel them accordingly, but I'm running into a Trouble with Prometheus relabel_configs Regex for Matching Specific URL Patterns. Prometheus is configured via command-line flags and a configuration file. *)", matching any source_labels. Alternatively, you can use action: drop to drop all of the metrics that match the regular expression. The idea is to give custom names to container ports, which must be scraped, so these names can be used later during relabeling phase for the discovered targets. 2. Anyone can say that you can use honor_labels, or temporal label for further rewriting Prometheusには様々な関数が存在しますが、その中でも異色を放っている関数として label_replace があります。 この関数は、PromQL中に任意のラベルの 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 pipeline has a prometheus. 6 Prometheus regex match on different labels. Querying prometheus label values with metric values. example. +'}" action: labeldrop regex: url_rule See these docs for details. then we apply regex: (. Add a relabel_configs block with the following structure: Please note that you must use metric_relabel_configs instead of relabel_configs if you want apply relabeling on the collected metrics. From convenience perspective, its easier to write human-readable regex using that, but as its not supported, we’ll see a workaround for that. labelKeep和labeldrop不操作’__’开头的标签，要操作需要先改名 Prometheus官方文档 入门指导 Instructions and example code for a P The example configuration demonstrates how to use Prometheus relabel configs to pass multiple targets to one blackbox_exporter. + action: keep 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=~". * Regex with various combinations of 'scrape_. Locate the scrape_configs section. I've seen that I can use relabelling to fix this. For example, the following relabeling rules are equivalent to the rules above, but are easier to understand and maintain: Prometheus metric relabel for value. relabel component and see how it acts on the following metrics. labels: # Prometheus Swarm - prometheus-job=myJobsName - prometheus-port=3000 - prometheus-scrape-network=network1 - prometheus-env=production The second line checks that the label equals network1;network1 so it will filter out the "duplicate" target on the other network (because the other one will be equals to network2;network1 ). In your case query will look like this: You can drop targets with relabel_config by using drop action. de. Example. jksdjkfs-2f16-11e7-3454-005056bf2fbf. ; hashmod - Hashes the concatenated labels, calculates its modulo modulus and writes the result to the target_label. from the /metrics page) that you want to manipulate that's where metric_relabel_configs applies. * replacement: server It'd be helpful if prometheus would allow to transform such labels, so that the issue can b We have unfortunately two systems which expose labels in both upper case and lower case. ; dropequal - Drop targets for which the concatenated source_labels do match target_label. It will split a string like foo. are not allowed in Prometheus label names. In this tutorial, you configure Alloy to collect metrics and send them to Prometheus. In this case, it will drop all metric data points coming out of Prometheus via remote write. : metric_relabel_configs: - source_labels: [ __name__ ] regex: 'istio_. I am trying to add a label to all jobs that I have. You signed in with another tab or window. Reload to refresh your session. 03. I'd recommend using this service for debugging of Prometheus target relabeling. The issue with prometheus. ; keep - Keeps metrics where regex Right now I'm scraping metrics from a Node Exporter. In this case, it uses instance as the source. However when pulling in my list of servers I realized that my service's metrics endpoint is /prometheus no /metrics. Here's an example: metric_relabel_configs: - source_labels: [__name__] regex: my_useless_metric. The default is "(. This is my current config: relabel_configs: - source_labels: [__address__] target_label: instance regex: ^test. scrape_configs: - job_name: "consul-example" consul_sd_configs: - server: 'localhost:8500' relabel_configs: - action: keep source_labels: [__meta_consul_service] regex: api. *' # Third target - source_labels I'm trying to relabel the __address__ property in Prometheus without any luck. The resulting You can use metric_relabel_configs to filter out already scraped values. The replace action substitutes a target label's value with a replacement value if the source label values match the regex. In contrast to the previous relabeling actions we learned about, the labelmap action regex-matches and acts on label names, not label values. Here's how to use it to replace IP addresses with hostnames: Open your Prometheus configuration file (usually prometheus. I want to filter some of them and not upload to my Grafana as they are overwhelming. 1 Prometheus multiple source label in relabel config. So, type_group will contain values, such as type1 and prometheus. Using regular expressions in Prometheus relabel_configs source_labels. In Sometimes it is needed to remove certain labels before storing metrics in Prometheus or VictoriaMetrics. Add action: append (action: keep_union?) to relabel config, with the following logic:. Example Metrics in prometheus. ), the configuration file defines everything related to scraping jobs and their instances, as well as which rule files to load. *" or cpu=~". scrape結果に含まれるlabelは弄くれない模様. *) to catch everything from the source label, and since there is only one group we use the replacement as ${1} Relabel instance to hostname in Prometheus. This annotation should be added in your pod definition: annotations: prometheus. Let's look at some example use cases for the labelkeep action. On the user side, Prometheus now supports new service discovery mechanisms. 👍 1 seravat reacted with thumbs up emoji All reactions I was trying to setup prometheus on my cluster so basically am trying to monitor services and deployment. e Prometheus-Relabel. Use case examples. The best way around You signed in with another tab or window. Thus, only alphanumeric characters plus underscore are allowed and it cannot start with a number. prometheus. port. Relabeling is configured using the relabel_config block in the Prometheus configuration file. How to aggregate based on one label value, but preserve the other label values? 2. *’) modulus; replacement (default ‘$1’) action (default ‘replace’) Some of these elements have defaults, others are required based on the value of the action element. A playground for Prometheus relabeling rules. I am presuming it's something along the lines of - source_labels: [__meta_dockerswarm_service_label_prometheus_port] regex: (\d+) target_label: __port__ replace: $1 action: replace Understanding Prometheus Regex Query Mismatches. e. Important notes: Labels with __ prefix are automatically removed after the relabeling, so there is no need in removing them instant selector (for example up{instance="localhost:8192"}), destination label: name of new label, replacement string (for example "$1"), source label: label whose value will be used to create new label, regex pattern: regex matcher for value of source label. So, for example, in a cluster of 1k targets and each exposing 1k metrics, you would have 1 million relabels with prometheus中的relabel. *' action: drop 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 Visit the blog I use the following config for Prometheus, and found no go_info and go_gc_duration_seconds metrics: config1 global: scrape_interval: 60s evaluation_interval: 15s scrape_configs: - job_na Modify the Prometheus configuration under the server section to specify resources and replica count: 3. * matches any text. The label name is left as is if the regex doesn’t match it. Prometheus metric relabel for specific value. Following up to @Maklaus answer to their question above, the keep action of write_relabel_configs can be used to only write certain metrics. Proposal. io/scrape: 'true' This is great - we want to monitor these guys with Prometheus. Once a relabeling step decides to drop a labeled object, no In Prometheus, I see that the endpoint is scraped, and the endpoint contains the fccid parameter. The drop action works like keep, but drops an object rather than keeping it. Advanced Service Discovery in Prometheus 0. The labelkeep action performs the following steps, in sequence:. com regex: 'example. Note This is a quick demonstration on how to use prometheus relabel configs, when you have scenarios for when example, you want to use a part of your hostname and assign it to a prometheus label. The regex option is applied to every label name in the target. 0 The suggestion outlined here allows scraping multiple endpoints per pod. Relabel node-exporter The regex option can contain arbitrary regular expression in RE2 format. os. The JSON Exporter emits metrics with an id label that has values This section provides examples that use the relabel_configs and metric_relabel_configs sections of the Prometheus receiver to modify the number and structure of prometheus. I can persist them selectively with something like this: metric_relabel_configs: - source_labels: [__name__] regex: (?i)(metric1|metric2|metric3) action: keep However I want to drop all of the other, non-matching metrics. For example, the following query should properly match I have two different metrics that I am trying to combine in a PromQL expression to write an alert. ) In both relabel_configs and metric_relabel_configs some real-world examples would go a long way. If there is no match, the object is removed from the final output list. 4 Using regular expressions in Prometheus relabel_configs source_labels. For example, the following relabeling rule drops all the label names starting with foo: - action: labeldrop regex: "foo. In case the source_labels is empty or the regex doesn't catch anything, is it possible to set a default value for replacement? For example for something like this: - source_labels: - Example code and files from "Prometheus: Up and Running" - examples/9/prometheus-deployment. ) This post explains how you can use Prometheus relabeling configuration to manipulate metrics to keep your storage clean and not pollute it with unnecessary data. Removing HA replica labels from relabel_configs: - source_labels: [path] regex: "test/name/([^/]*). instance comes from the __address__ label and represents a host and port from which the metric came. I am trying to filter EC2 instances in prometheus. com:9100"] But not find any valid config until now. The labelmap action performs the following steps, in sequence:. 0 Posted at: June 1, 2015 by Fabian Reinartz, Julius Volz. Regex is not working, dropping all metrics with regex . For example, the following relabeling rule drops all the label names starting with foo : - action: labeldrop When first learning about relabel configs in Prometheus you will encounter many examples that looks something like this: relabel_configs: - source_labels: [__meta_kubernetes_role] action: keep regex: regex: The regular expression to match against the concatenated source labels. grafana. 33. service. Prometheus multiple source label in relabel config. That’s it. _labels: [__meta For example I will have abc-def01. This week we released Prometheus v0.
