Kubernetes module
editKubernetes module
editThis module fetches metrics from Kubernetes several components:
All metricsets with the state_
prefix require hosts
field pointing to kube-state-metrics
service within the cluster, while the rest should be pointed to kubelet service. Check the
example configuration on how to do it.
The default metricsets are container
, node
, pod
, system
and volume
.
Compatibility
editThe Kubernetes module is tested with Kubernetes 1.13.x and 1.14.x
Dashboards for scheduler
and proxy
are not compatible with kibana versions below 7.2.0
Dashboard
editKubernetes module is shipped including default dashboards for apiserver
, controllermanager
, scheduler
and proxy
.
If you are using HA for those components, be aware that when gathering data from all instances the dashboard will usually show and average of the metrics. For those scenarios filtering by hosts or service address is possible.
Dashboards for controllermanager
scheduler
and proxy
are not compatible with kibana versions below 7.2.0

Example configuration
editThe Kubernetes module supports the standard configuration options that are described in Specify which modules to run. Here is an example configuration:
metricbeat.modules: # Node metrics, from kubelet: - module: kubernetes metricsets: - container - node - pod - system - volume period: 10s hosts: ["localhost:10255"] enabled: true #bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token #ssl.certificate_authorities: # - /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt #ssl.certificate: "/etc/pki/client/cert.pem" #ssl.key: "/etc/pki/client/cert.key" # Enriching parameters: add_metadata: true in_cluster: true # When used outside the cluster: #host: node_name #kube_config: ~/.kube/config # State metrics from kube-state-metrics service: - module: kubernetes enabled: true metricsets: - state_node - state_deployment - state_replicaset - state_statefulset - state_pod - state_container period: 10s hosts: ["kube-state-metrics:8080"] # Enriching parameters: add_metadata: true in_cluster: true # When used outside the cluster: #host: node_name #kube_config: ~/.kube/config # Kubernetes events - module: kubernetes enabled: true metricsets: - event # Kubernetes API server # (when running metricbeat as a pod) - module: kubernetes enabled: true metricsets: - apiserver hosts: ["https://${KUBERNETES_SERVICE_HOST}:${KUBERNETES_SERVICE_PORT}"] # Kubernetes proxy server # (when running metricbeat locally at hosts or as a daemonset + host network) - module: kubernetes enabled: true metricsets: - proxy hosts: ["localhost:10249"] period: 10s # Kubernetes controller manager # (URL and deployment will need to be modified to match the controller manager deployment) - module: kubernetes enabled: true metricsets: - controllermanager hosts: ["http://localhost:10252"] period: 10s # Kubernetes scheduler # (URL and deployment method will need to be adapted to match scheduler deployment) - module: kubernetes enabled: true metricsets: - scheduler hosts: ["localhost:10251"] period: 10s
This module supports TLS connections when using ssl
config field, as described in Specify SSL settings.
It also supports the options described in Standard HTTP config options.
Metricsets
editThe following metricsets are available:
