Managing Prometheus Instance Metrics

You can check the metrics of a common Prometheus instance, or a Prometheus instance for CCE/APM, and add/discard metrics.

Prerequisites

Your service has been connected for Prometheus monitoring. For details, see Managing Prometheus Instances.

Constraints

  • Only the common Prometheus instance, and Prometheus instance for CCE/APM support the functions of checking/adding/discarding metrics.
  • On the Metric Management page, you can query only the metrics reported in the last three hours.
  • Prometheus instances for CCE:

    Only the metrics reported by kube-prometheus-stack (later than 3.9.0) installed on CCE Add-ons or AOM Prometheus instance for CCE Integration Center can be discarded. Ensure that this add-on is running when discarding metrics.

    To view the kube-prometheus-stack status, log in to the CCE console and access the cluster page, choose Add-ons in the navigation pane, and locate that add-on on the right.
