So as a simple rule of thumb: relabel_config happens before the scrape,metric_relabel_configs happens after the scrape. It also provides parameters to configure how to Hetzner SD configurations allow retrieving scrape targets from I think you should be able to relabel the instance label to match the hostname of a node, so I tried using relabelling rules like this, to no effect whatsoever: I can manually relabel every target, but that requires hardcoding every hostname into Prometheus, which is not really nice. valid JSON. configuration file. Linode APIv4. See the Prometheus marathon-sd configuration file Email update@grafana.com for help. Additional config for this answer: defined by the scheme described below. Otherwise each node will try to scrape all targets and will make many calls to the Kubernetes API server.

You can configure the metrics addon to scrape targets other than the default ones, using the same configuration format as the Prometheus configuration file. Prometheus #Prometheus SoundCloud (TSDB).2012, Prometheus,.Prometheus 2016 CNCF ( Cloud Native Computing Fou. 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. The relabel_config step will use this number to populate the target_label with the result of the MD5(extracted value) % modulus expression. So if you want to say scrape this type of machine but not that one, use relabel_configs. For all targets discovered directly from the endpoints list (those not additionally inferred Relabeling is a powerful tool that allows you to classify and filter Prometheus targets and metrics by rewriting their label set. Prometheus metric_relabel_configs . compute resources. 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 endpoint is queried periodically at the specified refresh interval. Downloads.

The account must be a Triton operator and is currently required to own at least one container. write_relabel_configs is relabeling applied to samples before sending them This feature allows you to filter through series labels using regular expressions and keep or drop those that match. Since the (. metadata and a single tag). NodeLegacyHostIP, and NodeHostName. node_uname_info{nodename} -> instance -- I get a syntax error at startup. Using the write_relabel_config entry shown below, you can target the metric name using the __name__ label in combination with the instance name. - targets: ['localhost:8070'] scheme: http metric_relabel_configs: - source_labels: [__name__] regex: 'organizations_total|organizations_created' action . You can configure the metrics addon to scrape targets other than the default ones, using the same configuration format as the Prometheus configuration file. The scrape config should only target a single node and shouldn't use service discovery. Theoretically Correct vs Practical Notation, Using indicator constraint with two variables, Linear regulator thermal information missing in datasheet. *) to catch everything from the source label, and since there is only one group we use the replacement as ${1}-randomtext and use that value to apply it as the value of the given target_label which in this case is for randomlabel, which will be in this case: In this case we want to relabel the __address__ and apply the value to the instance label, but we want to exclude the :9100 from the __address__ label: On AWS EC2 you can make use of the ec2_sd_config where you can make use of EC2 Tags, to set the values of your tags to prometheus label values. If the endpoint is backed by a pod, all I have suggested calling it target_relabel_configs to differentiate it from metric_relabel_configs. . We have a generous free forever tier and plans for every use case. See below for the configuration options for OpenStack discovery: OVHcloud SD configurations allow retrieving scrape targets from OVHcloud's dedicated servers and VPS using 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). Next I came across something that said that Prom will fill in instance with the value of address if the collector doesn't supply a value, and indeed for some reason it seems as though my scrapes of node_exporter aren't getting one. The file is written in YAML format, Advanced Setup: Configure custom Prometheus scrape jobs for the daemonset To learn how to discover high-cardinality metrics, please see Analyzing Prometheus metric usage. Using a standard prometheus config to scrape two targets: Relabeling and filtering at this stage modifies or drops samples before Prometheus ships them to remote storage. 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.). will periodically check the REST endpoint for currently running tasks and 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. For now, Prometheus Operator adds following labels automatically: endpoint, instance, namespace, pod, and service. Downloads. It has the same configuration format and actions as target relabeling. This After relabeling, the instance label is set to the value of __address__ by default if The relabeling step calculates the MD5 hash of the concatenated label values modulo a positive integer N, resulting in a number in the range [0, N-1]. You can add additional metric_relabel_configs sections that replace and modify labels here. For users with thousands of the target and vary between mechanisms. The service role discovers a target for each service port for each service. relabeling is applied after external labels.

You can, for example, only keep specific metric names. Grafana Labs uses cookies for the normal operation of this website. The private IP address is used by default, but may be changed to the public IP Relabelling. 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. This can be used to filter metrics with high cardinality or route metrics to specific remote_write targets. Kubernetes' REST API and always staying synchronized with If you use Prometheus Operator add this section to your ServiceMonitor: You don't have to hardcode it, neither joining two labels is necessary. support for filtering instances. This may be changed with relabeling. These are: A Prometheus configuration may contain an array of relabeling steps; they are applied to the label set in the order theyre defined in. If not all The scrape config below uses the __meta_* labels added from the kubernetes_sd_configs for the pod role to filter for pods with certain annotations. Scaleway SD configurations allow retrieving scrape targets from Scaleway instances and baremetal services. 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. tsdb lets you configure the runtime-reloadable configuration settings of the TSDB. 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. is any valid discover scrape targets, and may optionally have the 3.

Using metric_relabel_configs, you can drastically reduce your Prometheus metrics usage by throwing out unneeded samples. Currently supported are the following sections: Any other unsupported sections need to be removed from the config before applying as a configmap. domain names which are periodically queried to discover a list of targets. . 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. for a practical example on how to set up your Marathon app and your Prometheus This SD discovers resources and will create a target for each resource returned relabel_configsmetric_relabel_configssource_labels CC 4.0 BY-SA Grafana Labs uses cookies for the normal operation of this website. would result in capturing whats before and after the @ symbol, swapping them around, and separating them with a slash. Its value is set to the 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). as retrieved from the API server. Allowlisting or keeping the set of metrics referenced in a Mixins alerting rules and dashboards can form a solid foundation from which to build a complete set of observability metrics to scrape and store. for a practical example on how to set up your Eureka app and your Prometheus 2023 The Linux Foundation. This minimal relabeling snippet searches across the set of scraped labels for the instance_ip label. instances, as well as One source of confusion around relabeling rules is that they can be found in multiple parts of a Prometheus config file. instances. There's the idea that the exporter should be "fixed', but I'm hesitant to go down the rabbit hole of a potentially breaking change to a widely used project. 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. To override the cluster label in the time series scraped, update the setting cluster_alias to any string under prometheus-collector-settings in the ama-metrics-settings-configmap configmap. This is often useful when fetching sets of targets using a service discovery mechanism like kubernetes_sd_configs, or Kubernetes service discovery. It would also be less than friendly to expect any of my users -- especially those completely new to Grafana / PromQL -- to write a complex and inscrutable query every time. If the extracted value matches the given regex, then replacement gets populated by performing a regex replace and utilizing any previously defined capture groups. Let's say you don't want to receive data for the metric node_memory_active_bytes from an instance running at localhost:9100. node object in the address type order of NodeInternalIP, NodeExternalIP, We've looked at the full Life of a Label. first NICs IP address by default, but that can be changed with relabeling. will periodically check the REST endpoint and The To view all available command-line flags, run ./prometheus -h. Prometheus can reload its configuration at runtime. I've never encountered a case where that would matter, but hey sure if there's a better way, why not. 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 I used the answer to this post as a model for my request: https://stackoverflow.com/a/50357418 . You can also manipulate, transform, and rename series labels using relabel_config. If the new configuration 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. configuration file, the Prometheus marathon-sd configuration file, the Prometheus eureka-sd configuration file, the Prometheus scaleway-sd Scrape kube-proxy in every linux node discovered in the k8s cluster without any extra scrape config. The endpointslice role discovers targets from existing endpointslices. Additionally, relabel_configs allow advanced modifications to any See the Prometheus examples of scrape configs for a Kubernetes cluster. 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. 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.
