By default, instance is set to __address__, which is $host:$port. in the file_sd_configs: Solution: If you want to retain these labels, the relabel_configs can rewrite the label multiple times be done the following way: Doing it like this, the manually-set instance in sd_configs takes precedence, but if it's not set the port is still stripped away. The __address__ label is set to the : address of the target. feature to replace the special __address__ label. We must make sure that all metrics are still uniquely labeled after applying labelkeep and labeldrop rules. create a target group for every app that has at least one healthy task. So as a simple rule of thumb: relabel_config happens before the scrape,metric_relabel_configs happens after the scrape. The purpose of this post is to explain the value of Prometheus relabel_config block, the different places where it can be found, and its usefulness in taming Prometheus metrics. address one target is discovered per port. The private IP address is used by default, but may be changed to the public IP - targets: ['localhost:8070'] scheme: http metric_relabel_configs: - source_labels: [__name__] regex: 'organizations_total|organizations_created' action . server sends alerts to.

Email update@grafana.com for help. from the /metrics page) that you want to manipulate that's where metric_relabel_configs applies. Posted by Ruan Prometheus relabeling to control which instances will actually be scraped. So without further ado, lets get into it! Prometheus Relabling Using a standard prometheus config to scrape two targets: - ip-192-168-64-29.multipass:9100 - ip-192-168-64-30.multipass:9100 metrics_config The metrics_config block is used to define a collection of metrics instances. Scrape coredns service in the k8s cluster without any extra scrape config. to Prometheus Users Thank you Simonm This is helpful, however, i found that under prometheus v2.10 you will need to use the following relabel_configs: - source_labels: [__address__] regex:. Prometheus supports relabeling, which allows performing the following tasks: Adding new label Updating existing label Rewriting existing label Updating metric name Removing unneeded labels. OpenStack SD configurations allow retrieving scrape targets from OpenStack Nova it gets scraped. Prometheus configuration file. Scrape the kubernetes api server in the k8s cluster without any extra scrape config. <__meta_consul_address>:<__meta_consul_service_port>. For instance, if you created a secret named kube-prometheus-prometheus-alert-relabel-config and it contains a file named additional-alert-relabel-configs.yaml, use the parameters below: Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. It may be a factor that my environment does not have DNS A or PTR records for the nodes in question. The following table has a list of all the default targets that the Azure Monitor metrics addon can scrape by default and whether it's initially enabled. To enable allowlisting in Prometheus, use the keep and labelkeep actions with any relabeling configuration. service port. If we provide more than one name in the source_labels array, the result will be the content of their values, concatenated using the provided separator. rev2023.3.3.43278. for a practical example on how to set up your Marathon app and your Prometheus See below for the configuration options for Kubernetes discovery: See this example Prometheus configuration file This service discovery uses the public IPv4 address by default, by that can be Our answer exist inside the node_uname_info metric which contains the nodename value. Prometheus keeps all other metrics. The ingress role discovers a target for each path of each ingress. By using the following relabel_configs snippet, you can limit scrape targets for this job to those whose Service label corresponds to app=nginx and port name to web: The initial set of endpoints fetched by kuberentes_sd_configs in the default namespace can be very large depending on the apps youre running in your cluster. sudo systemctl restart prometheus 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. port of a container, a single target is generated. One of the following roles can be configured to discover targets: The services role discovers all Swarm services relabel_configstargetmetric_relabel_configs relabel_configs drop relabel_configs: - source_labels: [__meta_ec2_tag_Name] regex: Example. contexts. The Linux Foundation has registered trademarks and uses trademarks. Relabeling is a powerful tool that allows you to classify and filter Prometheus targets and metrics by rewriting their label set. metric_relabel_configs are commonly used to relabel and filter samples before ingestion, and limit the amount of data that gets persisted to storage. The following meta labels are available for each target: See below for the configuration options for Kuma MonitoringAssignment discovery: The relabeling phase is the preferred and more powerful way See below for the configuration options for Eureka discovery: See the Prometheus eureka-sd configuration file If you're currently using Azure Monitor Container Insights Prometheus scraping with the setting monitor_kubernetes_pods = true, adding this job to your custom config will allow you to scrape the same pods and metrics. Using the __meta_kubernetes_service_label_app label filter, endpoints whose corresponding services do not have the app=nginx label will be dropped by this scrape job. interface. source_labels and separator Let's start off with source_labels. Scrape info about the prometheus-collector container such as the amount and size of timeseries scraped. Remote development environments that secure your source code and sensitive data Otherwise the custom configuration will fail validation and won't be applied. will periodically check the REST endpoint for currently running tasks and Targets may be statically configured via the static_configs parameter or Once Prometheus scrapes a target, metric_relabel_configs allows you to define keep, drop and replace actions to perform on scraped samples: This sample piece of configuration instructs Prometheus to first fetch a list of endpoints to scrape using Kubernetes service discovery (kubernetes_sd_configs). PuppetDB resources. of your services provide Prometheus metrics, you can use a Marathon label and ), the An example might make this clearer. windows_exporter: enabled: true metric_relabel_configs: - source_labels: [__name__] regex: windows_system_system_up_time action: keep . NodeLegacyHostIP, and NodeHostName. Heres a small list of common use cases for relabeling, and where the appropriate place is for adding relabeling steps. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Thats all for today! Does Counterspell prevent from any further spells being cast on a given turn? With this, the node_memory_Active_bytes metric which contains only instance and job labels by default, gets an additional nodename label that you can use in the description field of Grafana. way to filter tasks, services or nodes. The following relabeling would remove all {subsystem=""} labels but keep other labels intact. You can use a relabel_config to filter through and relabel: Youll learn how to do this in the next section. See the Prometheus examples of scrape configs for a Kubernetes cluster. When custom scrape configuration fails to apply due to validation errors, default scrape configuration will continue to be used. Note that exemplar storage is still considered experimental and must be enabled via --enable-feature=exemplar-storage. You can configure the metrics addon to scrape targets other than the default ones, using the same configuration format as the Prometheus configuration file. changed with relabeling, as demonstrated in the Prometheus scaleway-sd See this example Prometheus configuration file record queries, but not the advanced DNS-SD approach specified in Docker Swarm SD configurations allow retrieving scrape targets from Docker Swarm target is generated. One use for this is to exclude time series that are too expensive to ingest. (relabel_config) prometheus . EC2 SD configurations allow retrieving scrape targets from AWS EC2 Prometheus Monitoring subreddit. I've been trying in vai for a month to find a coherent explanation of group_left, and expressions aren't labels. We could offer this as an alias, to allow config file transition for Prometheus 3.x. The endpointslice role discovers targets from existing endpointslices. relabel_configs. configuration file, the Prometheus linode-sd For example, the following block would set a label like {env="production"}, While, continuing with the previous example, this relabeling step would set the replacement value to my_new_label. The pod role discovers all pods and exposes their containers as targets. IONOS SD configurations allows retrieving scrape targets from Of course, we can do the opposite and only keep a specific set of labels and drop everything else. They are applied to the label set of each target in order of their appearance The write_relabel_configs section defines a keep action for all metrics matching the apiserver_request_total|kubelet_node_config_error|kubelet_runtime_operations_errors_total regex, dropping all others. refresh interval. tracing_config configures exporting traces from Prometheus to a tracing backend via the OTLP protocol. Prometheus is an open-source monitoring and alerting toolkit that collects and stores its metrics as time series data. service account and place the credential file in one of the expected locations. One of the following types can be configured to discover targets: The container role discovers one target per "virtual machine" owned by the account. In this guide, weve presented an overview of Prometheuss powerful and flexible relabel_config feature and how you can leverage it to control and reduce your local and Grafana Cloud Prometheus usage. PrometheusGrafana. configuration file. You can't relabel with a nonexistent value in the request, you are limited to the different parameters that you gave to Prometheus or those that exists in the module use for the request (gcp,aws.). Alert relabeling is applied to alerts before they are sent to the Alertmanager. Mixins are a set of preconfigured dashboards and alerts. Relabeling 4.1 . relabeling does not apply to automatically generated timeseries such as up. determines the relabeling action to take: Care must be taken with labeldrop and labelkeep to ensure that metrics are This reduced set of targets corresponds to Kubelet https-metrics scrape endpoints. We have a generous free forever tier and plans for every use case. This service discovery uses the main IPv4 address by default, which that be You can't relabel with a nonexistent value in the request, you are limited to the different parameters that you gave to Prometheus or those that exists in the module use for the request (gcp,aws). For example, you may have a scrape job that fetches all Kubernetes Endpoints using a kubernetes_sd_configs parameter. Nomad SD configurations allow retrieving scrape targets from Nomad's from underlying pods), the following labels are attached. I used the answer to this post as a model for my request: https://stackoverflow.com/a/50357418 . Please find below an example from other exporter (blackbox), but same logic applies for node exporter as well. See this example Prometheus configuration file Use the following to filter IN metrics collected for the default targets using regex based filtering. Below are examples showing ways to use relabel_configs. To view every metric that is being scraped for debugging purposes, the metrics addon agent can be configured to run in debug mode by updating the setting enabled to true under the debug-mode setting in ama-metrics-settings-configmap configmap. The IAM credentials used must have the ec2:DescribeInstances permission to compute resources. For users with thousands of containers it Additional helpful documentation, links, and articles: How to set up and visualize synthetic monitoring at scale with Grafana Cloud, Using Grafana Cloud to drive manufacturing plant efficiency. Some of these special labels available to us are. Consider the following metric and relabeling step. The __scrape_interval__ and __scrape_timeout__ labels are set to the target's type Config struct {GlobalConfig GlobalConfig `yaml:"global"` AlertingConfig AlertingConfig `yaml:"alerting,omitempty"` RuleFiles []string `yaml:"rule_files,omitempty"` ScrapeConfigs []*ScrapeConfig `yaml:"scrape_configs,omitempty"` . . If you drop a label in a metric_relabel_configs section, it wont be ingested by Prometheus and consequently wont be shipped to remote storage. One use for this is ensuring a HA pair of Prometheus servers with different Prometheus is configured through a single YAML file called prometheus.yml. Using the write_relabel_config entry shown below, you can target the metric name using the __name__ label in combination with the instance name. Additional labels prefixed with __meta_ may be available during the In our config, we only apply a node-exporter scrape config to instances which are tagged PrometheusScrape=Enabled, then we use the Name tag, and assign its value to the instance tag, and the similarly we assign the Environment tag value to the environment promtheus label value. To drop a specific label, select it using source_labels and use a replacement value of "". By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. To filter by them at the metrics level, first keep them using relabel_configs by assigning a label name and then use metric_relabel_configs to filter. Using this feature, you can store metrics locally but prevent them from shipping to Grafana Cloud. For details on custom configuration, see Customize scraping of Prometheus metrics in Azure Monitor. ), but not system components (kubelet, node-exporter, kube-scheduler, .,) system components do not need most of the labels (endpoint . is it query? Files must contain a list of static configs, using these formats: As a fallback, the file contents are also re-read periodically at the specified Avoid downtime. This will cut your active series count in half. Or if we were in an environment with multiple subsystems but only wanted to monitor kata, we could keep specific targets or metrics about it and drop everything related to other services. the public IP address with relabeling. Since kubernetes_sd_configs will also add any other Pod ports as scrape targets (with role: endpoints), we need to filter these out using the __meta_kubernetes_endpoint_port_name relabel config. may contain a single * that matches any character sequence, e.g. Powered by Octopress, - targets: ['ip-192-168-64-29.multipass:9100'], - targets: ['ip-192-168-64-30.multipass:9100'], # Config: https://github.com/prometheus/prometheus/blob/release-2.36/config/testdata/conf.good.yml, ./prometheus.yml:/etc/prometheus/prometheus.yml, '--config.file=/etc/prometheus/prometheus.yml', '--web.console.libraries=/etc/prometheus/console_libraries', '--web.console.templates=/etc/prometheus/consoles', '--web.external-url=http://prometheus.127.0.0.1.nip.io', https://grafana.com/blog/2022/03/21/how-relabeling-in-prometheus-works/#internal-labels, https://prometheus.io/docs/prometheus/latest/configuration/configuration/#ec2_sd_config, Python Flask Forms with Jinja Templating , Logging With Docker Promtail and Grafana Loki, Ansible Playbook for Your Macbook Homebrew Packages.

The replace action is most useful when you combine it with other fields. By default, for all the default targets, only minimal metrics used in the default recording rules, alerts, and Grafana dashboards are ingested as described in minimal-ingestion-profile. These relabeling steps are applied before the scrape occurs and only have access to labels added by Prometheus Service Discovery. At a high level, a relabel_config allows you to select one or more source label values that can be concatenated using a separator parameter. - ip-192-168-64-29.multipass:9100 What can a lawyer do if the client wants him to be acquitted of everything despite serious evidence? To filter in more metrics for any default targets, edit the settings under default-targets-metrics-keep-list for the corresponding job you'd like to change. refresh failures. This SD discovers resources and will create a target for each resource returned The labelmap action is used to map one or more label pairs to different label names. Lets start off with source_labels. This service discovery uses the public IPv4 address by default, but that can be I see that the node exporter provides the metric node_uname_info that contains the hostname, but how do I extract it from there? Scrape kube-proxy in every linux node discovered in the k8s cluster without any extra scrape config. The HTTP header Content-Type must be application/json, and the body must be Zookeeper. Droplets API. configuration file defines everything related to scraping jobs and their Service API. In many cases, heres where internal labels come into play. If the endpoint is backed by a pod, all It is configuration file. Dropping metrics at scrape time with Prometheus It's easy to get carried away by the power of labels with Prometheus. relabeling is completed. You can extract a samples metric name using the __name__ meta-label. job. The __* labels are dropped after discovering the targets. If you use quotes or backslashes in the regex, you'll need to escape them using a backslash. to filter proxies and user-defined tags. via Uyuni API. prometheus.yml This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Endpoints are limited to the kube-system namespace. The following rule could be used to distribute the load between 8 Prometheus instances, each responsible for scraping the subset of targets that end up producing a certain value in the [0, 7] range, and ignoring all others. Scrape kube-state-metrics in the k8s cluster (installed as a part of the addon) without any extra scrape config. Prometheus queries: How to give a default label when it is missing? Its value is set to the Alertmanagers may be statically configured via the static_configs parameter or Kubernetes' REST API and always staying synchronized with in the configuration file), which can also be changed using relabeling. for a practical example on how to set up your Eureka app and your Prometheus 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. - Key: Environment, Value: dev. The first relabeling rule adds {__keep="yes"} label to metrics with mountpoint matching the given regex. Open positions, Check out the open source projects we support Labels are sets of key-value pairs that allow us to characterize and organize whats actually being measured in a Prometheus metric. To summarize, the above snippet fetches all endpoints in the default Namespace, and keeps as scrape targets those whose corresponding Service has an app=nginx label set. The CloudWatch agent with Prometheus monitoring needs two configurations to scrape the Prometheus metrics. The account must be a Triton operator and is currently required to own at least one container. prometheustarget 12key metrics_relabel_configsrelabel_configsmetrics_relabel_configsrelabel_configstarget metric_relabel_configs 0 APP "" sleepyzhang 0 7638 0 0 filepath from which the target was extracted. The global configuration specifies parameters that are valid in all other configuration via the MADS v1 (Monitoring Assignment Discovery Service) xDS API, and will create a target for each proxy If a task has no published ports, a target per task is the public IP address with relabeling. If a job is using kubernetes_sd_configs to discover targets, each role has associated __meta_* labels for metrics. is not well-formed, the changes will not be applied. In this scenario, on my EC2 instances I have 3 tags: After changing the file, the prometheus service will need to be restarted to pickup the changes. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. In those cases, you can use the relabel To collect all metrics from default targets, in the configmap under default-targets-metrics-keep-list, set minimalingestionprofile to false. For each endpoint For readability its usually best to explicitly define a relabel_config. instances. metric_relabel_configs by contrast are applied after the scrape has happened, but before the data is ingested by the storage system. stored in Zookeeper. In advanced configurations, this may change. configuration file, this example Prometheus configuration file, the Prometheus hetzner-sd Serversets are commonly See below for the configuration options for Uyuni discovery: See the Prometheus uyuni-sd configuration file The regex supports parenthesized capture groups which can be referred to later on. A configuration reload is triggered by sending a SIGHUP to the Prometheus process or I am attempting to retrieve metrics using an API and the curl response appears to be in the correct format.
