This integration is used to collect logs and metrics from Kubernetes clusters. Time series index mode enabled for metrics data streams.

This integration requires kube-state-metrics, which is not included with Kubernetes by default. For dashboards to properly populate, the kube-state-metrics service must be deployed to your Kubernetes cluster

As one of the main pieces provided for Kubernetes monitoring, this integration is capable of fetching metrics from several components:

Some of the previous components are running on each of the Kubernetes nodes (like kubelet or proxy) while others provide a single cluster-wide endpoint. This is important to determine the optimal configuration and running strategy for the different datasets included in the integration.

Kubernetes endpoints and metricsets

edit

Kubernetes module is a bit complex as its internal datasets require access to a wide variety of endpoints.

This section highlights and introduces some groups of datasets with similar endpoint access needs. For more details on the datasets see configuration example and the datasets sections below.

node / system / pod / container / module / volume

edit

The datasets container, node, pod, system and volume require access to the kubelet endpoint in each of the Kubernetes nodes, hence it’s recommended to include them as part of an Agent DaemonSet or standalone Agents running on the hosts.

Depending on the version and configuration of Kubernetes nodes, kubelet might provide a read only http port (typically 10255), which is used in some configuration examples. But in general, and lately, this endpoint requires SSL (https) access (to port 10250 by default) and token based authentication.

state_* and event

edit

State_* datasets are enabled by default.

All datasets with the state_ prefix require hosts field pointing to kube-state-metrics service within the cluster. As the service provides cluster-wide metrics, there’s no need to fetch them per node, hence the recommendation is to run these datasets as part of an Agent Deployment with one only replica.

Generally kube-state-metrics runs a Deployment and is accessible via a service called kube-state-metrics on kube-system namespace, which will be the service to use in our configuration.

apiserver

edit

The apiserver dataset requires access to the Kubernetes API, which should be easily available in all Kubernetes environments. Depending on the Kubernetes configuration, the API access might require SSL (https) and token based authentication.

proxy

edit

The proxy dataset requires access to the proxy endpoint in each of Kubernetes nodes, hence it’s recommended to configure it as a part of an Agent DaemonSet.

scheduler and controllermanager

edit

These datasets require access to the Kubernetes controller-manager and scheduler endpoints. By default, these pods run only on master nodes, and they are not exposed via a Service, but there are different strategies available for its configuration:

  • Create Kubernetes Services to make kube-controller-manager and kube-scheduler available and configure the datasets to point to these services as part of an Agent Deployment.
  • Run these datasets as part an Agent Daemonset (with HostNetwork setting) with a nodeSelector to only run on Master nodes.

These datasets are not enabled by default.

In some "As a Service" Kubernetes implementations, like GKE, the master nodes or even the pods running on the masters won’t be visible. In these cases it won’t be possible to use scheduler and controllermanager metricsets.

container-logs

edit

The container-logs dataset requires access to the log files in each Kubernetes node where the container logs are stored. This defaults to /var/log/containers/*${kubernetes.container.id}.log.

Routing

edit

The container-logs data stream allows routing logs to a different dataset or namespace using pod annotations.

For example, suppose you are running Nginx on your Kubernetes cluster, and you want to drive the Nginx container logs into a dedicated dataset or namespace. By annotating the pod with elastic.co/namespace: nginx, the integration will send all the container logs to the nginx namespace.

To learn more about routing container-logs, see https://docs.elastic.co/integrations/kubernetes/container-logs.

Preserve original event

edit

The agent can be configured to set the tag preserve_original_event on container-logs using pod annotation.

For example, suppose you are routing your Nginx container logs into a dedicated dataset or namespace as described above to make use of the Nginx fleet integration. Enabling preserve_original_event on the Nginx integration will have no effect since the logs were shipped via kubernetes integration and not Nginx. As well, you may not want to have all original events from all Nginx pods preserved as well.

By annotating the pod with elastic.co/preserve_original_event: 'true', the integration will add the tag preserve_original_event as it would be done by the nginx integration otherwise.

audit-logs

edit

The audit-logs dataset requires access to the log files on each Kubernetes node where the audit logs are stored. This defaults to /var/log/kubernetes/kube-apiserver-audit.log.

Compatibility

edit

The Kubernetes package is tested with Kubernetes [1.28.x - 1.31.x] versions

Dashboard

edit

Kubernetes integration is shipped including default dashboards for apiserver, controllermanager, overview, proxy and scheduler.

If you are using HA for those components, be aware that when gathering data from all instances the dashboard will usually show the average of the metrics. For those scenarios filtering by hosts or service address is possible.

Cluster selector in overview dashboard helps in distinguishing and filtering metrics collected from multiple clusters. If you want to focus on a subset of the Kubernetes clusters for monitoring a specific scenario, this cluster selector could be a handy tool. Note that this selector gets populated from the orchestrator.cluster.name field that may not always be available. This field gets its value from sources like kube_config, kubeadm-config configMap, and Google Cloud’s meta API for GKE. If the sources mentioned above don’t provide this value, metricbeat will not report it. However, you can always use processors to set this field and utilize it in the cluster overview dashboard.
