Overview
This document describes the monitoring data collection and display features at the four levels of cluster, workload, Pod and Container provided by elastic TKE (EKS).
prerequisite
An elastic cluster with a status of "running" has been created. For more information, see This API creates a Cluster .
Operation step
- Log in to the TKE console and select [in Left sidebar] Elastic cluster ].
- On the "Elastic clusters" list page, select the cluster ID that you want to operate.
- On the cluster resource management page, refer to the following documents to view monitoring and setting alarms:
