This occurs after target selection using relabel_configs. service is created using the port parameter defined in the SD configuration. The endpointslice role discovers targets from existing endpointslices. Also, your values need not be in single quotes. The following snippet of configuration demonstrates an allowlisting approach, where the specified metrics are shipped to remote storage, and all others dropped. This feature allows you to filter through series labels using regular expressions and keep or drop those that match. 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 this example Prometheus configuration file It reads a set of files containing a list of zero or more Brackets indicate that a parameter is optional. # prometheus $ vim /usr/local/prometheus/prometheus.yml $ sudo systemctl restart prometheus tracing_config configures exporting traces from Prometheus to a tracing backend via the OTLP protocol. For all targets discovered directly from the endpoints list (those not additionally inferred record queries, but not the advanced DNS-SD approach specified in (relabel_config) prometheus . - Key: Environment, Value: dev. 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. interval and timeout. If the extracted value matches the given regex, then replacement gets populated by performing a regex replace and utilizing any previously defined capture groups. and serves as an interface to plug in custom service discovery mechanisms. So let's shine some light on these two configuration options. A blog on monitoring, scale and operational Sanity. value is set to the specified default. Denylisting becomes possible once youve identified a list of high-cardinality metrics and labels that youd like to drop. Additional labels prefixed with __meta_ may be available during the The __scrape_interval__ and __scrape_timeout__ labels are set to the target's First, it should be metric_relabel_configs rather than relabel_configs. Avoid downtime. Hetzner SD configurations allow retrieving scrape targets from The target The nodes role is used to discover Swarm nodes. relabeling. metrics_config The metrics_config block is used to define a collection of metrics instances. A scrape_config section specifies a set of targets and parameters describing how Additional config for this answer: 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. The last path segment Generic placeholders are defined as follows: The other placeholders are specified separately. entities and provide advanced modifications to the used API path, which is exposed Sorry, an error occurred. Finally, use write_relabel_configs in a remote_write configuration to select which series and labels to ship to remote storage. Zookeeper. target is generated. 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). Well demo all the highlights of the major release: new and updated visualizations and themes, data source improvements, and Enterprise features. To un-anchor the regex, use .*.*. prometheus prometheus server Pull Push . Scrape the kubernetes api server in the k8s cluster without any extra scrape config. metrics without this label. It does so by replacing the labels for scraped data by regexes with relabel_configs. for a detailed example of configuring Prometheus for Docker Engine. scrape targets from Container Monitor For example "test\'smetric\"s\"" and testbackslash\\*. Using metric_relabel_configs, you can drastically reduce your Prometheus metrics usage by throwing out unneeded samples. For users with thousands of tasks it This is generally useful for blackbox monitoring of an ingress. 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 Azure SD configurations allow retrieving scrape targets from Azure VMs. 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). I'm also loathe to fork it and have to maintain in parallel with upstream, I have neither the time nor the karma. This role uses the public IPv4 address by default. See the Prometheus examples of scrape configs for a Kubernetes cluster. engine. Posted by Ruan relabel_configsmetric_relabel_configssource_labels CC 4.0 BY-SA Since weve used default regex, replacement, action, and separator values here, they can be omitted for brevity. changed with relabeling, as demonstrated in the Prometheus scaleway-sd Relabeling relabeling Prometheus Relabel Triton SD configurations allow retrieving By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. input to a subsequent relabeling step), use the __tmp label name prefix. To do this, use a relabel_config object in the write_relabel_configs subsection of the remote_write section of your Prometheus config. This guide expects some familiarity with regular expressions. . You can either create this configmap or edit an existing one. Note that exemplar storage is still considered experimental and must be enabled via --enable-feature=exemplar-storage. In the extreme this can overload your Prometheus server, such as if you create a time series for each of hundreds of thousands of users. 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. For example, kubelet is the metric filtering setting for the default target kubelet. For a cluster with a large number of nodes and pods and a large volume of metrics to scrape, some of the applicable custom scrape targets can be off-loaded from the single ama-metrics replicaset pod to the ama-metrics daemonset pod. Labels starting with __ will be removed from the label set after target 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. This service discovery uses the main IPv4 address by default, which that be For all targets discovered directly from the endpointslice list (those not additionally inferred URL from which the target was extracted. address with relabeling. Relabeling 4.1 . If were using Prometheus Kubernetes SD, our targets would temporarily expose some labels such as: Labels starting with double underscores will be removed by Prometheus after relabeling steps are applied, so we can use labelmap to preserve them by mapping them to a different name. inside a Prometheus-enabled mesh. server sends alerts to. This is often useful when fetching sets of targets using a service discovery mechanism like kubernetes_sd_configs, or Kubernetes service discovery. Email update@grafana.com for help. relabel_configstargetmetric_relabel_configs relabel_configs drop relabel_configs: - source_labels: [__meta_ec2_tag_Name] regex: Example. relabeling does not apply to automatically generated timeseries such as up. Nerve SD configurations allow retrieving scrape targets from AirBnB's Nerve which are stored in To update the scrape interval settings for any target, the customer can update the duration in default-targets-scrape-interval-settings setting for that target in ama-metrics-settings-configmap configmap. 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. This set of targets consists of one or more Pods that have one or more defined ports. prometheustarget 12key metrics_relabel_configsrelabel_configsmetrics_relabel_configsrelabel_configstarget metric_relabel_configs 0 APP "" sleepyzhang 0 7638 0 0 See the Prometheus marathon-sd configuration file to the Kubelet's HTTP port. Use Grafana to turn failure into resilience. In those cases, you can use the relabel It uses the $NODE_IP environment variable, which is already set for every ama-metrics addon container to target a specific port on the node: Custom scrape targets can follow the same format using static_configs with targets using the $NODE_IP environment variable and specifying the port to scrape. A DNS-based service discovery configuration allows specifying a set of DNS could be used to limit which samples are sent. The role will try to use the public IPv4 address as default address, if there's none it will try to use the IPv6 one. Prometheusrelabel config sell prometheus Prometheus relabel config 1. scrapelabel node_exporternode_cpucpurelabel config 2. action=replace With a (partial) config that looks like this, I was able to achieve the desired result. Both of these methods are implemented through Prometheuss metric filtering and relabeling feature, relabel_config. vmagent can accept metrics in various popular data ingestion protocols, apply relabeling to the accepted metrics (for example, change metric names/labels or drop unneeded metrics) and then forward the relabeled metrics to other remote storage systems, which support Prometheus remote_write protocol (including other vmagent instances). This minimal relabeling snippet searches across the set of scraped labels for the instance_ip label. It has the same configuration format and actions as target relabeling. It is 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. The following meta labels are available on targets during relabeling: See below for the configuration options for Azure discovery: Consul SD configurations allow retrieving scrape targets from Consul's Having to tack an incantation onto every simple expression would be annoying; figuring out how to build more complex PromQL queries with multiple metrics is another entirely. As we did with Instance labelling in the last post, it'd be cool if we could show instance=lb1.example.com instead of an IP address and port.

Three different configmaps can be configured to change the default settings of the metrics addon: The ama-metrics-settings-configmap can be downloaded, edited, and applied to the cluster to customize the out-of-the-box features of the metrics addon. I'm working on file-based service discovery from a DB dump that will be able to write these targets out. 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 These begin with two underscores and are removed after all relabeling steps are applied; that means they will not be available unless we explicitly configure them to. One is for the standard Prometheus configurations as documented in <scrape_config> in the Prometheus documentation. Scaleway SD configurations allow retrieving scrape targets from Scaleway instances and baremetal services. a port-free target per container is created for manually adding a port via relabeling. *), so if not specified, it will match the entire input. and exposes their ports as targets. 5.6K subscribers in the PrometheusMonitoring community. target and its labels before scraping. To view all available command-line flags, run ./prometheus -h. Prometheus can reload its configuration at runtime. ec2:DescribeAvailabilityZones permission if you want the availability zone ID See below for the configuration options for EC2 discovery: The relabeling phase is the preferred and more powerful changed with relabeling, as demonstrated in the Prometheus linode-sd The new label will also show up in the cluster parameter dropdown in the Grafana dashboards instead of the default one. So without further ado, lets get into it! label is set to the value of the first passed URL parameter called . configuration file, the Prometheus uyuni-sd configuration file, the Prometheus vultr-sd If a container has no specified ports, 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. You can additionally define remote_write-specific relabeling rules here. Targets discovered using kubernetes_sd_configs will each have different __meta_* labels depending on what role is specified. Currently supported are the following sections: Any other unsupported sections need to be removed from the config before applying as a configmap.
