Querying Metrics

Scenario

Cloud Eye monitors the running status of the CDM cluster. You can obtain the monitoring metrics of CDM on the Cloud Eye management console.

Monitored data requires a period of time for transmission and display. The status of CDM displayed on the Cloud Eye page is the status obtained 5 to 10 minutes before. You can view the monitored data of a newly created CDM cluster 5 to 10 minutes later.

Prerequisites

  • The CDM cluster is running properly.

    If a cluster fails to shut down or restart, or is unavailable, its monitoring metrics cannot be viewed on Cloud Eye. You can view the monitored data only after the cluster is restarted or recovered.

  • The cluster has been properly running for about 10 minutes.

    The monitored data and graphs are available for a newly created cluster after the cluster runs for at least 10 minutes.

Procedure

  1. Log in to the CDM management console.
  2. Choose Cluster Management. Choose More > View Metric. The Cloud Eye console is displayed.
  3. On the CDM monitoring page, you can view the graphs of all monitoring metrics.
