This post explains how you can use Prometheus relabeling configuration to manipulate metrics to keep your storage clean and not pollute it with unnecessary data. user{name="Julien Pivotto"} Julien "roidelapluie" Pivotto @roidelapluie Sysadmin at inuits Automation, monitoring, HA Grafana and Prometheus user/contributor Relabeling can be … A typical Prometheus environment consists of integrations that scrape your applications for four metric types; counters, gauges, summaries, and aggregated histograms. In this situation, your metric would be identified as a gauge rather than a counter. So as I didn’t found it easily, I thought about writing a small article to show you how to do it without needed to spend the same time as I did. Posted by 2 hours ago.

Thankfully there's a way to deal with this without having to turn off monitoring or deploy a new version of your code. ; Metric Relabelling. Prometheus is an open-source time-series database used for monitoring and alerting. vmagent. Prometheus Operator provides easy monitoring definitions for Kubernetes services and deployment and management of Prometheus instances.. In the next post, we will dive into the 4 different types of Prometheus metrics (counters, gauges, histograms and summaries) and when to use them. While the process for adding Prometheus metrics to a Python application is well documented in the prometheus_client documentation, dealing with adding metrics when you only know what the metric name or labels are going to be at runtime is trickier.Normal metric classes expect to be declared at module level so the default collector can pick them up. vmagent is a tiny but mighty agent which helps you collect metrics from various sources and store them in VictoriaMetrics or any other Prometheus-compatible storage systems that support the remote_write protocol.. .). Describe the bug If the __name__ label is changed using prometheus relabel configs, the prometheus receiver fails to populate metric metadata.. The host.docker.internal tells a Prometheus instance running inside a docker container to connect to the host’s 8081 port where Raper runs from a JAR. node - application prefix. __name__ is a particular label that will enable you to rename your metrics before being ingested in the Prometheus Timeseries Database. One of these configuration plugins is about relabeling, and this is a great thing. See Kubernetes Environments and Docker Environments. Reaper doesn’t do anything with the metrics. Alert relabeling is applied after external labels. These metrics can be used to do things like find out the start time of alerts or just display a count of currently ... with the name of the alert as its value. The ALERTS metric in Prometheus also has an alertstate label, but this is not passed on to the version of the alert that Alertmanager sees.

Just don’t overuse this feature too much because it has to be executed with every scrape, so if at all possible, you should prefer to fix the exporter instead of relying on the heavy use of relabeling. Prometheus has its own scripting language called PromQL. This topic shows you how to configure Docker, set up Prometheus to run as a Docker container, and monitor your Docker instance using Prometheus. To relabel a metric based on labels set by the metric source you need to use `metric_relabel_configs`, which are applied on the data after collection. For example, use the remote write dashboard we automatically create when you set up your integration.. Mapping of Prometheus metric types . This means you can run a service on multiple hosts with each instance publishing its own metrics under the same name and later in Prometheus you can distinguish them by instance. It will make it so metrics with names container_tasks_state and container_memory_failures_total are completely dropped and will not be stored in the database. Anything not dropped by the above line will be dropped by this line. Thanks, Kevin. I’ve been using it for some time until I realized about a feature that I was desperate to know how to do, but I couldn’t find anywhere clearly define.

Here’s an example of relabeling the metric tracking a repair progress. One or more labels, which are simply key-value pairs that distinguish each metric with the same name (e.

And after that point, this will be as it will have that name since the beginning. metric_relabel_configs offers one way around that. You can use write_relabel_configs to relabel or restrict the metrics you write to remote storage. This configuration file template will be read by the Thanos sidecar component and it will generate the actual configuration file, which will in turn be consumed by the Prometheus container running in the same pod. 2. Installing Prometheus and Grafana. Although the input does allow some basic whitelist and blacklist behaviour against the metric name before ingesting in Splunk, it will be more efficient and flexible to do this on the Prometheus server using write_relabel_configs if that is possible. Select the metric from Prometheus named as “myapp_client_connected”. job_name: ... # List of metric relabel configurations. However, the prometheus server updates the metadata cache before applying relabel rules, meaning the metadata cache stores metadata based on … Estimated reading time: 8 minutes. WHat am i … The relabel_config parameter is not supported. By default, Prometheus is installed alongside Istio, allowing you to use Grafana and Kiali to view metrics for both the Istio control plane and your Envoy-injected workloads. This regex contains a list of all metrics found in the kubernetes-mixin dashboards. Which … Prometheus keeps all other metrics. ok I’m at a loss here. Clone via HTTPS Clone with Git or checkout with SVN using the repository’s web address. You can drop some labels or even metrics, change their name, and many other mutations. Relabel is a very powerful function embedded in Prometheus. source_labels A blog on monitoring, scale and operational Sanity. Defaults to 2. Collect Docker metrics with Prometheus. These clusters are typically launched via the same control plane deployed either to AWS, as a CloudFormation template, or Azure, as an ARM template. which Prometheus converts to metric_relabel_configs: - source_labels: [__name__, POD_NAME] separator: ; regex: ^saas_health:;(. By adding Grafana as a visualization layer, we can easily set up a monitoring stack for our monitoring stack. Motivation. This will return the 20 biggest time series by metric name and job, which one is the problem should be obvious. Let’s take a closer look. For detailed information visit the Prometheus documentation at prometheus.io. Zero or more process-specific filtering configurations (optional). kubectl get pod -n prometheus NAME READY STATUS RESTARTS AGE prometheus-alertmanager-78b5c64fd5-ch7hb 2/2 Running 0 67m prometheus-kube-state-metrics-685dccc6d8-h88dv 1/1 Running 0 67m prometheus-node-exporter-8xw2r 1/1 Running 0 67m prometheus-node-exporter-l5pck 1/1 Running 0 67m prometheus-pushgateway-567987c9fd-5mbdn 1/1 Running 0 67m prometheus-server … You can configure Docker as a Prometheus target. a Counter (see Metric Types); When designing your own metrics, please use the base units suggested in the documentation.

The writeRelabelConfigs section instructs Prometheus to check the __name__ meta-label (the metric name) of a scraped time series, and match it against the regex defined by the regex parameter. How to use that is relatively easy, is as any other relabel process, and I’d like to show you a sample about how to do it.
