2.11. Accessing metrics of all services as a cluster administrator

Prerequisites

• Log in to the web console as a cluster administrator or a user with view permissions for all namespaces.
• Optionally, log in with the oc command as well.

Procedure

• Using the Metrics web interface:

  1. Go to the OpenShift Container Platform web console, switch to the Administrator Perspective, and click Monitoring Metrics.

     注意

     Cluster administrators, when using the Administrator Perspective, have access to all cluster metrics and to custom service metrics from all projects.

     注意

     Only cluster administrators have access to the third-party UIs provided with OpenShift Container Platform Monitoring.

  2. Use the PromQL interface to run queries for your services.

• Using the Thanos Querier UI:

  注意

  In a future release, the route to the Thanos Querier UI will be deprecated in favor of the web console.

  1. List routes for the openshift-monitoring namespace:

     $ oc -n openshift-monitoring get routes

     The output shows the URL for the Thanos Querier UI:

     NAME                HOST/PORT
     ...
     thanos-querier      thanos-querier-openshift-monitoring.apps.example.devcluster.openshift.com

  2. Navigate to the listed URL. Here you can see all metrics from all namespaces.
