Issue

Prometheus metrics cannot be displayed.

Cause

The name of your cluster is the same as the name of a cluster that you have deleted from the region where your cluster resides. However, the Prometheus plug-in of the deleted cluster is not uninstalled from the Application Real-Time Monitoring Service (ARMS) console. Consequently, the Prometheus plug-in failed to be installed in your cluster.

Solution

  1. Go to the ARMS console and uninstall the Prometheus plug-in of the deleted cluster. For more information, see Uninstall the Prometheus agent.
  2. Install the Prometheus plug-in in your cluster. For more information, see Enable ARMS Prometheus.
