Monitoring Managed Service for Kubernetes cluster state

Managed Service for Kubernetes automatically sends cluster metrics to Yandex Monitoring. Metrics are available for the following Kubernetes objects:

• Container
• Master
• Node
• Pod
• Persistent volume

You can find metrics description in Yandex Monitoring metric reference.

How to get statisticsHow to get statistics

There are several alternative ways:

• View the statistics in the management console. It shows only the metrics for your master, nodes, and pods.

• Open the Monitoring web interface. It shows all Managed Service for Kubernetes metrics.

• Export metrics using the Monitoring API. Thus you can get only numerical values of metrics without visualization.

• Install Metrics Provider. You can use it to transmit metrics in two directions:

  • From Kubernetes objects to monitoring systems and automatic scaling systems
  • From Monitoring to Kubernetes objects

• Install Prometheus Operator to use the Yandex Managed Service for Prometheus® monitoring system. This way you can work with dashboards in Grafana and take advantage of Prometheus.
