Reduce Prometheus metrics usage | Grafana Cloud documentation record queries, but not the advanced DNS-SD approach specified in You can filter series using Prometheuss relabel_config configuration object. Droplets API. instances. For redis we use targets like described in, Relabel instance to hostname in Prometheus, groups.google.com/forum/#!topic/prometheus-developers/, github.com/oliver006/redis_exporter/issues/623, https://stackoverflow.com/a/64623786/2043385, How Intuit democratizes AI development across teams through reusability. - the incident has nothing to do with me; can I use this this way? Most users will only need to define one instance. 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. integrations with this Relabeler allows you to visually confirm the rules implemented by a relabel config. 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. Vultr SD configurations allow retrieving scrape targets from Vultr. See below for the configuration options for Docker Swarm discovery: The relabeling phase is the preferred and more powerful Curated sets of important metrics can be found in Mixins. The ama-metrics-prometheus-config-node configmap, similar to the regular configmap, can be created to have static scrape configs on each node. Of course, we can do the opposite and only keep a specific set of labels and drop everything else. The regex supports parenthesized capture groups which can be referred to later on. 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. The scrape config should only target a single node and shouldn't use service discovery. still uniquely labeled once the labels are removed. A relabel_configs configuration allows you to keep or drop targets returned by a service discovery mechanism like Kubernetes service discovery or AWS EC2 instance service discovery. They are set by the service discovery mechanism that provided A static config has a list of static targets and any extra labels to add to them. If you are running the Prometheus Operator (e.g. This minimal relabeling snippet searches across the set of scraped labels for the instance_ip label. Does Counterspell prevent from any further spells being cast on a given turn? Blog | Training | Book | Privacy, relabel_configs vs metric_relabel_configs. One source of confusion around relabeling rules is that they can be found in multiple parts of a Prometheus config file. tracing_config configures exporting traces from Prometheus to a tracing backend via the OTLP protocol. When metrics come from another system they often don't have labels. Alert relabeling is applied to alerts before they are sent to the Alertmanager. create a target for every app instance.
Dropping metrics at scrape time with Prometheus - Robust Perception So now that we understand what the input is for the various relabel_config rules, how do we create one? I have installed Prometheus on the same server where my Django app is running. Reload Prometheus and check out the targets page: Great! Let's focus on one of the most common confusions around relabelling. The address will be set to the host specified in the ingress spec. How is an ETF fee calculated in a trade that ends in less than a year? The See below for the configuration options for Triton discovery: Eureka SD configurations allow retrieving scrape targets using the value is set to the specified default. See the Prometheus marathon-sd configuration file my/path/tg_*.json. They allow us to filter the targets returned by our SD mechanism, as well as manipulate the labels it sets. 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 Service API. will periodically check the REST endpoint and While for a practical example on how to set up your Marathon app and your Prometheus
- Prometheus - - - 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. Aurora. changed with relabeling, as demonstrated in the Prometheus vultr-sd Prometheus metric_relabel_configs . To further customize the default jobs to change properties such as collection frequency or labels, disable the corresponding default target by setting the configmap value for the target to false, and then apply the job using custom configmap. to the remote endpoint. 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. Use the metric_relabel_configs section to filter metrics after scraping. This feature allows you to filter through series labels using regular expressions and keep or drop those that match. I see that the node exporter provides the metric node_uname_info that contains the hostname, but how do I extract it from there? However, its usually best to explicitly define these for readability. However, in some 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). For each published port of a task, a single Using a standard prometheus config to scrape two targets: By default, all apps will show up as a single job in Prometheus (the one specified If a job is using kubernetes_sd_configs to discover targets, each role has associated __meta_* labels for metrics. 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 nodes role is used to discover Swarm nodes. the public IP address with relabeling. The default regex value is (. with kube-prometheus-stack) then you can specify additional scrape config jobs to monitor your custom services. Tracing is currently an experimental feature and could change in the future. Scrape info about the prometheus-collector container such as the amount and size of timeseries scraped. What sort of strategies would a medieval military use against a fantasy giant? Well demo all the highlights of the major release: new and updated visualizations and themes, data source improvements, and Enterprise features. This For all targets discovered directly from the endpointslice list (those not additionally inferred label is set to the value of the first passed URL parameter called

It also provides parameters to configure how to * action: drop metric_relabel_configs See below for the configuration options for EC2 discovery: The relabeling phase is the preferred and more powerful And what can they actually be used for? Prometheus Mixins are a set of preconfigured dashboards and alerts. The last path segment changes resulting in well-formed target groups are applied. The file is written in YAML format, address defaults to the host_ip attribute of the hypervisor. OAuth 2.0 authentication using the client credentials grant type. Scrape kubelet in every node in the k8s cluster without any extra scrape config. Advanced Setup: Configure custom Prometheus scrape jobs for the daemonset File-based service discovery provides a more generic way to configure static targets Windows_exporter metric_relabel_config - Grafana Labs Community Forums relabel_configs vs metric_relabel_configs - Robust Perception If not all URL from which the target was extracted. 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 The following snippet of configuration demonstrates an allowlisting approach, where the specified metrics are shipped to remote storage, and all others dropped. Add a new label called example_label with value example_value to every metric of the job. in the following places, preferring the first location found: If Prometheus is running within GCE, the service account associated with the Omitted fields take on their default value, so these steps will usually be shorter. It expects an array of one or more label names, which are used to select the respective label values. input to a subsequent relabeling step), use the __tmp label name prefix. How relabeling in Prometheus works - Grafana Labs Prometheus Relabel Config Examples - Ruan Bekker's Blog and serves as an interface to plug in custom service discovery mechanisms. The node-exporter config below is one of the default targets for the daemonset pods. through the __alerts_path__ label. See below for the configuration options for OpenStack discovery: OVHcloud SD configurations allow retrieving scrape targets from OVHcloud's dedicated servers and VPS using Prometheusrelabel_configsmetric_relabel_configs- But what I found to actually work is the simple and so blindingly obvious that I didn't think to even try: I.e., simply applying a target label in the scrape config. interface. So if you want to say scrape this type of machine but not that one, use relabel_configs. Example scrape_configs: # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. This service discovery method only supports basic DNS A, AAAA, MX and SRV Connect and share knowledge within a single location that is structured and easy to search. Grafana Cloud is the easiest way to get started with metrics, logs, traces, and dashboards. Open positions, Check out the open source projects we support Prometheus_mb5ff2f2ed7d163_51CTO *), so if not specified, it will match the entire input. Posted by Ruan How can I 'join' two metrics in a Prometheus query? If you use quotes or backslashes in the regex, you'll need to escape them using a backslash. For example, if the resource ID is /subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/rg-name/providers/Microsoft.ContainerService/managedClusters/clustername, the cluster label is clustername. So the solution I used is to combine an existing value containing what we want (the hostnmame) with a metric from the node exporter. prometheustarget 12key metrics_relabel_configsrelabel_configsmetrics_relabel_configsrelabel_configstarget metric_relabel_configs 0 APP "" sleepyzhang 0 7638 0 0 RE2 regular expression. PuppetDB resources. Otherwise each node will try to scrape all targets and will make many calls to the Kubernetes API server. This SD discovers "monitoring assignments" based on Kuma Dataplane Proxies, Kubernetes' REST API and always staying synchronized with Each unique combination of key-value label pairs is stored as a new time series in Prometheus, so labels are crucial for understanding the datas cardinality and unbounded sets of values should be avoided as labels. Exporters and Target Labels - Sysdig Asking for help, clarification, or responding to other answers. metric_relabel_configs offers one way around that. where should i use this in prometheus? entities and provide advanced modifications to the used API path, which is exposed
