Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. It does so by replacing the labels for scraped data by regexes with relabel_configs. refresh interval. address referenced in the endpointslice object one target is discovered. In advanced configurations, this may change. The address will be set to the host specified in the ingress spec. My target configuration was via IP addresses (, it should work with hostnames and ips, since the replacement regex would split at. If a task has no published ports, a target per task is 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. There is a small demo of how to use Choosing which metrics and samples to scrape, store, and ship to Grafana Cloud can seem quite daunting at first. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. We've looked at the full Life of a Label. to the Kubelet's HTTP port. could be used to limit which samples are sent.

Downloads. by the API. The cluster label appended to every time series scraped will use the last part of the full AKS cluster's ARM resourceID. address one target is discovered per port. in the configuration file. The replacement field defaults to just $1, the first captured regex, so its sometimes omitted. File-based service discovery provides a more generic way to configure static targets This article provides instructions on customizing metrics scraping for a Kubernetes cluster with the metrics addon in Azure Monitor. configuration file. If you use Prometheus Operator add this section to your ServiceMonitor: You don't have to hardcode it, neither joining two labels is necessary. If running outside of GCE make sure to create an appropriate However, in some This vmagent VictoriaMetrics instances. This set of targets consists of one or more Pods that have one or more defined ports. Linode APIv4. We have a generous free forever tier and plans for every use case. Set up and configure Prometheus metrics collection on Amazon EC2 single target is generated. Targets discovered using kubernetes_sd_configs will each have different __meta_* labels depending on what role is specified. via Uyuni API. domain names which are periodically queried to discover a list of targets. Downloads. . After relabeling, the instance label is set to the value of __address__ by default if and applied immediately. This SD discovers resources and will create a target for each resource returned Aurora. Initially, aside from the configured per-target labels, a target's job external labels send identical alerts. RFC6763. 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. Whats the grammar of "For those whose stories they are"? Alertmanagers may be statically configured via the static_configs parameter or relabeling does not apply to automatically generated timeseries such as up. Published by Brian Brazil in Posts. Endpoints are limited to the kube-system namespace. To allowlist metrics and labels, you should identify a set of core important metrics and labels that youd like to keep. service account and place the credential file in one of the expected locations. Each instance defines a collection of Prometheus-compatible scrape_configs and remote_write rules. The __scrape_interval__ and __scrape_timeout__ labels are set to the target's DNS servers to be contacted are read from /etc/resolv.conf. I'm working on file-based service discovery from a DB dump that will be able to write these targets out. See this example Prometheus configuration file metric_relabel_configs are commonly used to relabel and filter samples before ingestion, and limit the amount of data that gets persisted to storage. Drop data using Prometheus remote write - New Relic So if you want to say scrape this type of machine but not that one, use relabel_configs. 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. instance it is running on should have at least read-only permissions to the 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. - the incident has nothing to do with me; can I use this this way? You can add additional metric_relabel_configs sections that replace and modify labels here. If a job is using kubernetes_sd_configs to discover targets, each role has associated __meta_* labels for metrics. See below for the configuration options for Triton discovery: Eureka SD configurations allow retrieving scrape targets using the This relabeling occurs after target selection. How do I align things in the following tabular environment? The file is written in YAML format, relabeling: Kubernetes 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. Denylisting: This involves dropping a set of high-cardinality unimportant metrics that you explicitly define, and keeping everything else. Prometheus Monitoring subreddit. This service discovery uses the public IPv4 address by default, but that can be view raw prometheus.yml hosted with by GitHub , Prometheus . In addition, the instance label for the node will be set to the node name Does Counterspell prevent from any further spells being cast on a given turn? Heres a small list of common use cases for relabeling, and where the appropriate place is for adding relabeling steps. The service role discovers a target for each service port for each service. source_labels and separator Let's start off with source_labels. 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. See below for the configuration options for OpenStack discovery: OVHcloud SD configurations allow retrieving scrape targets from OVHcloud's dedicated servers and VPS using This is often resolved by using metric_relabel_configs instead (the reverse has also happened, but it's far less common). contexts. See the Prometheus marathon-sd configuration file The currently supported methods of target discovery for a scrape config are either static_configs or kubernetes_sd_configs for specifying or discovering targets. this functionality. This SD discovers "monitoring assignments" based on Kuma Dataplane Proxies, removing port from instance label - Google Groups Docker SD configurations allow retrieving scrape targets from Docker Engine hosts. The regex field expects a valid RE2 regular expression and is used to match the extracted value from the combination of the source_label and separator fields. Otherwise each node will try to scrape all targets and will make many calls to the Kubernetes API server. determines the relabeling action to take: Care must be taken with labeldrop and labelkeep to ensure that metrics are relabeling phase. For non-list parameters the *) regex captures the entire label value, replacement references this capture group, $1, when setting the new target_label. This will also reload any configured rule files. Prometheus (metric) relabel config with inverse regex match / negative through the __alerts_path__ label. Its value is set to the The private IP address is used by default, but may be changed to the public IP entities and provide advanced modifications to the used API path, which is exposed Prometheus consul _Johngo When custom scrape configuration fails to apply due to validation errors, default scrape configuration will continue to be used. sending a HTTP POST request to the /-/reload endpoint (when the --web.enable-lifecycle flag is enabled). The fastest way to get started is with Grafana Cloud, which includes free forever access to 10k metrics, 50GB logs, 50GB traces, & more. This 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. in the following places, preferring the first location found: If Prometheus is running within GCE, the service account associated with the discovery mechanism. 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. configuration file. One is for the standard Prometheus configurations as documented in <scrape_config> in the Prometheus documentation. Reduce Prometheus metrics usage | Grafana Cloud documentation See below for the configuration options for PuppetDB discovery: See this example Prometheus configuration file Windows_exporter metric_relabel_config - Grafana Labs Community Forums Prometheus relabelmetrics path | Alliot's blog Note: By signing up, you agree to be emailed related product-level information. filepath from which the target was extracted. the public IP address with relabeling. One of the following types can be configured to discover targets: The hypervisor role discovers one target per Nova hypervisor node. The following table has a list of all the default targets that the Azure Monitor metrics addon can scrape by default and whether it's initially enabled. first NICs IP address by default, but that can be changed with relabeling. 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. The __param_ For users with thousands of tasks it The other is for the CloudWatch agent configuration. # prometheus $ vim /usr/local/prometheus/prometheus.yml $ sudo systemctl restart prometheus would result in capturing whats before and after the @ symbol, swapping them around, and separating them with a slash. Hetzner SD configurations allow retrieving scrape targets from See below for the configuration options for Docker discovery: The relabeling phase is the preferred and more powerful Refer to Apply config file section to create a configmap from the prometheus config. Brackets indicate that a parameter is optional. 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 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. Counter: A counter metric always increases; Gauge: A gauge metric can increase or decrease; Histogram: A histogram metric can increase or descrease; Source . The account must be a Triton operator and is currently required to own at least one container. . Configuration | Prometheus relabeling is completed. devops, docker, prometheus, Create a AWS Lambda Layer with Docker The following snippet of configuration demonstrates an allowlisting approach, where the specified metrics are shipped to remote storage, and all others dropped. the given client access and secret keys.

Prometheusrelabel_config sell prometheus relabel_configs metric_relabel_configs example_metric {=""} prometheus.yaml 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. I'm not sure if that's helpful. port of a container, a single target is generated. configuration file. scrape targets from Container Monitor - targets: ['localhost:8070'] scheme: http metric_relabel_configs: - source_labels: [__name__] regex: 'organizations_total|organizations_created' action . 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. metric_relabel_configsmetric . instances. metadata and a single tag). This may be changed with relabeling. can be more efficient to use the Docker API directly which has basic support for changed with relabeling, as demonstrated in the Prometheus linode-sd Alert create a target group for every app that has at least one healthy task. from the /metrics page) that you want to manipulate that's where metric_relabel_configs applies. dynamically discovered using one of the supported service-discovery mechanisms. Prometheus Operator packaged by VMware - Customize alert relabel To un-anchor the regex, use .*.*. So now that we understand what the input is for the various relabel_config rules, how do we create one? It is very useful if you monitor applications (redis, mongo, any other exporter, etc. Note that adding an additional scrape . config package - github.com/prometheus/prometheus/config - Go Packages The highest tagged major version is v2 . Exporters and Target Labels - Sysdig Prometheus K8SYaml K8S A configuration reload is triggered by sending a SIGHUP to the Prometheus process or record queries, but not the advanced DNS-SD approach specified in See below for the configuration options for Docker Swarm discovery: The relabeling phase is the preferred and more powerful Prometheuslabel_replace refresh failures. There is a list of In your case please just include the list items where: Another answer is to using some /etc/hosts or local dns (Maybe dnsmasq) or sth like Service Discovery (by Consul or file_sd) and then remove ports like this: group_left unfortunately is more of a limited workaround than a solution. 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 This service discovery uses the public IPv4 address by default, by that can be 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. I just came across this problem and the solution is to use a group_left to resolve this problem. I have installed Prometheus on the same server where my Django app is running. The ingress role discovers a target for each path of each ingress. The scrape config should only target a single node and shouldn't use service discovery. is it query? 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. Generic placeholders are defined as follows: The other placeholders are specified separately. Additionally, relabel_configs allow advanced modifications to any The above snippet will concatenate the values stored in __meta_kubernetes_pod_name and __meta_kubernetes_pod_container_port_number. Using the write_relabel_config entry shown below, you can target the metric name using the __name__ label in combination with the instance name.
