The regex is This piece of remote_write configuration sets the remote endpoint to which Prometheus will push samples. Prometheus is an open-source monitoring and alerting toolkit that collects and stores its metrics as time series data. instances. is not well-formed, the changes will not be applied. Tutorial - Configure Prometheus | Couchbase Developer Portal 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. The hashmod action provides a mechanism for horizontally scaling Prometheus. Whats the grammar of "For those whose stories they are"? r/kubernetes I've been collecting a list of k8s/container tools and sorting them by the number of stars in Github, so far the most complete k8s/container list I know of with almost 250 entries - hoping this is useful for someone else besides me - looking for feedback, ideas for improvement and contributors The other is for the CloudWatch agent configuration. But still that shouldn't matter, I dunno why node_exporter isn't supplying any instance label at all since it does find the hostname for the info metric (where it doesn't do me any good). Recall that these metrics will still get persisted to local storage unless this relabeling configuration takes place in the metric_relabel_configs section of a scrape job. Difference between relabel_config and metric_relabel_config - Google Groups The scrape intervals have to be set by customer in the correct format specified here, else the default value of 30 seconds will be applied to the corresponding targets. If running outside of GCE make sure to create an appropriate For users with thousands of However, in some Setup monitoring with Prometheus and Grafana in Kubernetes Start monitoring your Kubernetes Geoffrey Mariette in Better Programming Create Your Python's Custom Prometheus Exporter Tony in Dev Genius K8s ChatGPT Bot For Intelligent Troubleshooting Stefanie Lai in Dev Genius All You Need to Know about Debugging Kubernetes Cronjob Help Status The __scrape_interval__ and __scrape_timeout__ labels are set to the target's relabeling. The relabel_configs section is applied at the time of target discovery and applies to each target for the job. This service discovery method only supports basic DNS A, AAAA, MX and SRV Prometheus metric_relabel_configs . If the endpoint is backed by a pod, all Why does Mister Mxyzptlk need to have a weakness in the comics? Nomad SD configurations allow retrieving scrape targets from Nomad's An example might make this clearer. A DNS-based service discovery configuration allows specifying a set of DNS This occurs after target selection using relabel_configs. single target is generated. 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. If a container has no specified ports, which rule files to load. anchored on both ends. The pod role discovers all pods and exposes their containers as targets. Document real world examples of using relabel_config #341 - GitHub locations, amount of data to keep on disk and in memory, etc. After changing the file, the prometheus service will need to be restarted to pickup the changes. So if you want to say scrape this type of machine but not that one, use relabel_configs. Initially, aside from the configured per-target labels, a target's job Prometheusrelabel_config sell prometheus relabel_configs metric_relabel_configs example_metric {=""} prometheus.yaml The service role discovers a target for each service port for each service. See below for the configuration options for Scaleway discovery: Uyuni SD configurations allow retrieving scrape targets from managed systems relabel_configs: - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_scrape] action: keep regex: true // keep targets with label __meta_kubernetes_service_annotation_prometheus_io_scrape equals 'true', // which means the user added prometheus.io/scrape: true in the service's annotation. It does so by replacing the labels for scraped data by regexes with relabel_configs. To collect all metrics from default targets, in the configmap under default-targets-metrics-keep-list, set minimalingestionprofile to false. . Prometheus To learn how to discover high-cardinality metrics, please see Analyzing Prometheus metric usage. This configuration does not impact any configuration set in metric_relabel_configs or relabel_configs. Email update@grafana.com for help. For now, Prometheus Operator adds following labels automatically: endpoint, instance, namespace, pod, and service. Relabel configs allow you to select which targets you want scraped, and what the target labels will be. Publishing the application's Docker image to a containe This block would match the two values we previously extracted, However, this block would not match the previous labels and would abort the execution of this specific relabel step. This relabeling occurs after target selection. Connect and share knowledge within a single location that is structured and easy to search. engine. For reference, heres our guide to Reducing Prometheus metrics usage with relabeling. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. It reads a set of files containing a list of zero or more Posted by Ruan The HTTP header Content-Type must be application/json, and the body must be The additional container ports of the pod, not bound to an endpoint port, are discovered as targets as well. Prometheus needs to know what to scrape, and that's where service discovery and relabel_configs come in. Grafana Labs uses cookies for the normal operation of this website. When metrics come from another system they often don't have labels. This is often useful when fetching sets of targets using a service discovery mechanism like kubernetes_sd_configs, or Kubernetes service discovery. - Key: Environment, Value: dev. scrape targets from Container Monitor The tasks role discovers all Swarm tasks It fetches targets from an HTTP endpoint containing a list of zero or more Understanding and using the multi-target exporter pattern - Prometheus As metric_relabel_configs are applied to every scraped timeseries, it is better to improve instrumentation rather than using metric_relabel_configs as a workaround on the Prometheus side.

How is an ETF fee calculated in a trade that ends in less than a year? Before applying these techniques, ensure that youre deduplicating any samples sent from high-availability Prometheus clusters. This is often resolved by using metric_relabel_configs instead (the reverse has also happened, but it's far less common). If shipping samples to Grafana Cloud, you also have the option of persisting samples locally, but preventing shipping to remote storage. If the new configuration These relabeling steps are applied before the scrape occurs and only have access to labels added by Prometheus Service Discovery. Docker Swarm SD configurations allow retrieving scrape targets from Docker Swarm Open positions, Check out the open source projects we support Reducing Prometheus metrics usage with relabeling, Common use cases for relabeling in Prometheus, The targets scrape interval (experimental), Special labels set set by the Service Discovery mechanism, Special prefix used to temporarily store label values before discarding them, When you want to ignore a subset of applications; use relabel_config, When splitting targets between multiple Prometheus servers; use relabel_config + hashmod, When you want to ignore a subset of high cardinality metrics; use metric_relabel_config, When sending different metrics to different endpoints; use write_relabel_config. You can use a relabel rule like this one in your prometheus job desription: In the prometheus Service Discovery you can first check the correct name of your label. 11 aylei pushed a commit to aylei/docs that referenced this issue on Oct 28, 2019 Update feature description in overview and readme ( prometheus#341) efb2912 - Key: PrometheusScrape, Value: Enabled Below are examples of how to do so.

In the previous example, we may not be interested in keeping track of specific subsystems labels anymore. To learn more about the general format for a relabel_config block, please see relabel_config from the Prometheus docs. Prometheus also provides some internal labels for us. Why do academics stay as adjuncts for years rather than move around? For each declared changes resulting in well-formed target groups are applied. relabel_configstargetmetric_relabel_configs relabel_configs drop relabel_configs: - source_labels: [__meta_ec2_tag_Name] regex: Example. port of a container, a single target is generated. - Key: Name, Value: pdn-server-1 communicate with these Alertmanagers. from underlying pods), the following labels are attached: If the endpoints belong to a service, all labels of the, For all targets backed by a pod, all labels of the. A static_config allows specifying a list of targets and a common label set Relabel configs allow you to select which targets you want scraped, and what the target labels will 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.). Prometheus 30- Enter relabel_configs, a powerful way to change metric labels dynamically. Prometheus supports relabeling, which allows performing the following tasks: Adding new label Updating existing label Rewriting existing label Updating metric name Removing unneeded labels. to filter proxies and user-defined tags. prometheustarget 12key metrics_relabel_configsrelabel_configsmetrics_relabel_configsrelabel_configstarget metric_relabel_configs 0 APP "" sleepyzhang 0 7638 0 0 integrations After saving the config file switch to the terminal with your Prometheus docker container and stop it by pressing ctrl+C and start it again to reload the configuration by using the existing command. are published with mode=host. They are applied to the label set of each target in order of their appearance for a practical example on how to set up Uyuni Prometheus configuration.

This is experimental and could change in the future. For each endpoint prefix is guaranteed to never be used by Prometheus itself. Hetzner Cloud API and This is to ensure that different components that consume this label will adhere to the basic alphanumeric convention. 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.
