OAuth 2.0 authentication using the client credentials grant type. Prometheus Cheatsheets My Cheatsheet Repository View on GitHub Prometheus Cheatsheets. For users with thousands of tasks it In advanced configurations, this may change. Use __address__ as the source label only because that label will always exist and will add the label for every target of the job. Refresh the page, check Medium 's site status,. See below for the configuration options for Docker discovery: The relabeling phase is the preferred and more powerful relabeling is applied after external labels. There are Mixins for Kubernetes, Consul, Jaeger, and much more. See below for the configuration options for Uyuni discovery: See the Prometheus uyuni-sd configuration file for a detailed example of configuring Prometheus for Kubernetes. For example, if a Pod backing the Nginx service has two ports, we only scrape the port named web and drop the other. This can be used to filter metrics with high cardinality or route metrics to specific remote_write targets. Relabel configs allow you to select which targets you want scraped, and what the target labels will be. Counter: A counter metric always increases; Gauge: A gauge metric can increase or decrease; Histogram: A histogram metric can increase or descrease; Source . The label will end with '.pod_node_name'. The default Prometheus configuration file contains the following two relabeling configurations: - action: replace source_labels: [__meta_kubernetes_pod_uid] target_label: sysdig_k8s_pod_uid - action: replace source_labels: [__meta_kubernetes_pod_container_name] target_label: sysdig_k8s_pod_container_name inside a Prometheus-enabled mesh. Any label pairs whose names match the provided regex will be copied with the new label name given in the replacement field, by utilizing group references (${1}, ${2}, etc). One of the following types can be configured to discover targets: The container role discovers one target per "virtual machine" owned by the account. For example, you may have a scrape job that fetches all Kubernetes Endpoints using a kubernetes_sd_configs parameter. instances, as well as Connect Grafana to data sources, apps, and more, with Grafana Alerting, Grafana Incident, and Grafana OnCall, Frontend application observability web SDK, Try out and share prebuilt visualizations, Contribute to technical documentation provided by Grafana Labs, Help build the future of open source observability software The other is for the CloudWatch agent configuration. Metric Sorry, an error occurred. metric_relabel_configs are commonly used to relabel and filter samples before ingestion, and limit the amount of data that gets persisted to storage. It does so by replacing the labels for scraped data by regexes with relabel_configs. and applied immediately. Prometheus applies this relabeling and dropping step after performing target selection using relabel_configs and metric selection and relabeling using metric_relabel_configs. If the extracted value matches the given regex, then replacement gets populated by performing a regex replace and utilizing any previously defined capture groups. This is most commonly used for sharding multiple targets across a fleet of Prometheus instances. Catalog API. It 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). The Linux Foundation has registered trademarks and uses trademarks. Serverset data must be in the JSON format, the Thrift format is not currently supported. This feature allows you to filter through series labels using regular expressions and keep or drop those that match. service account and place the credential file in one of the expected locations.

I've never encountered a case where that would matter, but hey sure if there's a better way, why not. stored in Zookeeper. service is created using the port parameter defined in the SD configuration. for a detailed example of configuring Prometheus for Docker Engine. configuration file, the Prometheus uyuni-sd configuration file, the Prometheus vultr-sd 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. instance it is running on should have at least read-only permissions to the You can apply a relabel_config to filter and manipulate labels at the following stages of metric collection: This sample configuration file skeleton demonstrates where each of these sections lives in a Prometheus config: Use relabel_configs in a given scrape job to select which targets to scrape. Finally, use write_relabel_configs in a remote_write configuration to select which series and labels to ship to remote storage. sending a HTTP POST request to the /-/reload endpoint (when the --web.enable-lifecycle flag is enabled). 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. can be more efficient to use the Swarm API directly which has basic support for We could offer this as an alias, to allow config file transition for Prometheus 3.x. Docker SD configurations allow retrieving scrape targets from Docker Engine hosts. instances. 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. Each pod of the daemonset will take the config, scrape the metrics, and send them for that node. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. My target configuration was via IP addresses (, it should work with hostnames and ips, since the replacement regex would split at. See below for the configuration options for GCE discovery: Credentials are discovered by the Google Cloud SDK default client by looking So let's shine some light on these two configuration options. Changes to all defined files are detected via disk watches This can be useful when local Prometheus storage is cheap and plentiful, but the set of metrics shipped to remote storage requires judicious curation to avoid excess costs. This is often useful when fetching sets of targets using a service discovery mechanism like kubernetes_sd_configs, or Kubernetes service discovery. The relabeling phase is the preferred and more powerful We must make sure that all metrics are still uniquely labeled after applying labelkeep and labeldrop rules. The endpoint is queried periodically at the specified refresh interval. Only engine. For now, Prometheus Operator adds following labels automatically: endpoint, instance, namespace, pod, and service. To enable denylisting in Prometheus, use the drop and labeldrop actions with any relabeling configuration. label is set to the value of the first passed URL parameter called . This Prometheus K8SYaml K8S will periodically check the REST endpoint and Why does Mister Mxyzptlk need to have a weakness in the comics? There are seven available actions to choose from, so lets take a closer look. following meta labels are available on all targets during interface. 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 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. could be used to limit which samples are sent. If the relabel action results in a value being written to some label, target_label defines to which label the replacement should be written. Find centralized, trusted content and collaborate around the technologies you use most. A static_config allows specifying a list of targets and a common label set Monitoring Docker container metrics using cAdvisor, Use file-based service discovery to discover scrape targets, Understanding and using the multi-target exporter pattern, Monitoring Linux host metrics with the Node Exporter, the Prometheus digitalocean-sd Targets discovered using kubernetes_sd_configs will each have different __meta_* labels depending on what role is specified. has the same configuration format and actions as target relabeling. As we saw before, the following block will set the env label to the replacement provided, so {env="production"} will be added to the labelset. The instance role discovers one target per network interface of Nova ), but not system components (kubelet, node-exporter, kube-scheduler, .,) system components do not need most of the labels (endpoint . You can configure the metrics addon to scrape targets other than the default ones, using the same configuration format as the Prometheus configuration file. Published by Brian Brazil in Posts Tags: prometheus, relabelling, service discovery Share on Blog | Training | Book | Privacy Which is frowned on by upstream as an "antipattern" because apparently there is an expectation that instance be the only label whose value is unique across all metrics in the job. Prometheus Monitoring subreddit. URL from which the target was extracted. with this feature. prometheus prometheus server Pull Push . , __name__ () node_cpu_seconds_total mode idle (drop). Using relabeling at the target selection stage, you can selectively choose which targets and endpoints you want to scrape (or drop) to tune your metric usage. external labels send identical alerts. Alert relabeling is applied to alerts before they are sent to the Alertmanager. The account must be a Triton operator and is currently required to own at least one container. With a (partial) config that looks like this, I was able to achieve the desired result. scrape targets from Container Monitor The reason is that relabeling can be applied in different parts of a metrics lifecycle from selecting which of the available targets wed like to scrape, to sieving what wed like to store in Prometheus time series database and what to send over to some remote storage. 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. Heres a small list of common use cases for relabeling, and where the appropriate place is for adding relabeling steps. In those cases, you can use the relabel They are set by the service discovery mechanism that provided The file is written in YAML format, source_labels and separator Let's start off with source_labels. - targets: ['localhost:8070'] scheme: http metric_relabel_configs: - source_labels: [__name__] regex: 'organizations_total|organizations_created' action . Configuration file To specify which configuration file to load, use the --config.file flag. A configuration reload is triggered by sending a SIGHUP to the Prometheus process or The currently supported methods of target discovery for a scrape config are either static_configs or kubernetes_sd_configs for specifying or discovering targets. Also, your values need not be in single quotes. You can use a relabel_config to filter through and relabel: Youll learn how to do this in the next section. Scrape info about the prometheus-collector container such as the amount and size of timeseries scraped. Making statements based on opinion; back them up with references or personal experience. This service discovery uses the The labels can be used in the relabel_configs section to filter targets or replace labels for the targets. I have suggested calling it target_relabel_configs to differentiate it from metric_relabel_configs. So if there are some expensive metrics you want to drop, or labels coming from the scrape itself (e.g. See the Debug Mode section in Troubleshoot collection of Prometheus metrics for more details. Sending data from multiple high-availability Prometheus instances, relabel_configs vs metric_relabel_configs, Advanced Service Discovery in Prometheus 0.14.0, Relabel_config in a Prometheus configuration file, Scrape target selection using relabel_configs, Metric and label selection using metric_relabel_configs, Controlling remote write behavior using write_relabel_configs, Samples and labels to ingest into Prometheus storage, Samples and labels to ship to remote storage. target and its labels before scraping. For each declared Multiple relabeling steps can be configured per scrape configuration.
