The Prometheus Node Exporter is a single static binary that you can install via tarball.

You first need to find out in which component the rule is defined (here it is kuberentesControlPlane).NOTE: While the Prometheus Node Exporter is for *nix systems, there is the Windows exporter for Windows that serves an analogous purpose. Here the alert KubeStatefulSetReplicasMismatch is being filtered out of the group kubernetes-apps.

These changes can be assigned to a local variable and then added to the local kp object as seen in the examples above. Knowing which rules to change, the user can now use functions from the Jsonnet standard library to make these changes.īelow are examples of both a filter and an adjustment being made to the default rules. alerts for Prometheus and dashboards for Grafana: yum install vz. This dashboard includes panels for the following metrics: CPU Usage. To quickly setup Prometheus nodeexporter. The alerting rules can be found in kube-prometheus/components/mixin/alerts exporter, and port 9100 is used by the node exporter. Monitoring Linux host metrics, with beautiful Grafana dashboard. The recording rules can be found in kube-prometheus/components/mixin/rules (import 'kube-prometheus/addons/pyrra.libsonnet') +Īlong with adding additional rules, we give the user the option to filter or adjust the existing rules imported by kube-prometheus/main.libsonnet.

(import 'kube-prometheus/addons/custom-metrics.libsonnet') + docker container & OS node (nodeexporter, cadvisor) docker cadvisor. (import 'kube-prometheus/addons/static-etcd.libsonnet') + Now go to your Grafana dashboard SERVERIP:3000 and configure.

Prometheus rules and Grafana dashboards in specific follow theįor both the Prometheus rules and the Grafana dashboards Kubernetes ConfigMaps are generated within kube-prometheus.

At some point one might like to extend them, the purpose of this document is to explain how to do this.Īll manifests of kube-prometheus are generated using jsonnet. Kube-prometheus ships with a set of default Prometheus rules and Grafana dashboards.
