Viewing and Customizing Cluster Monitoring Metrics

Updated at: Nov 08, 2019 GMT+08:00

MRS cluster nodes are classified into management nodes, control nodes, and data nodes. The change trends of key host monitoring metrics on each type of node can be calculated and displayed as curve charts in reports based on the customized periods. If a host belongs to multiple node types, the metric statistics will be repeatedly collected.

This section provides overview of MRS clusters and describes how to view, customize, and export node monitoring metrics on MRS Manager.

Method 1:

  1. Choose Clusters > Active Clusters and click a cluster name to go to the cluster details page.
  2. Click the Dashboard tab. Then, you can view the monitoring metric report of the cluster in the lower part of the page.
  3. To view or export reports of other metrics, click View next to Cluster Manager in the Basic Information area to access the MRS Manager page. For details, see Accessing MRS Manager.
  4. On the MRS Manager page, view, customize, and export the node monitoring metric report. For details, see Dashboard.

Method 2 (Applicable to Versions Later Than MRS 2.0.1):

  1. Log in to the MRS management console.
  2. Choose Clusters > Active Clusters and click a cluster name to go to the cluster details page.
  3. Click the Dashboard tab.
  4. In Period, specify a period to view monitoring data. The options are as follows:

    • Real time
    • Last 3 hours
    • Last 6 hours

    1. Click Customize and select monitoring metrics to be displayed.
      MRS supports a maximum of 14 monitoring metrics, but at most 12 customized monitoring metrics can be displayed on the page.
      • Cluster Host Health Status
      • Cluster Network Read Speed Statistics
      • Host Network Read Speed Distribution
      • Host Network Write Speed Distribution

      • Cluster Memory Usage Statistics
      • Host Memory Usage Distribution
      • Cluster Network Write Speed Statistics
      • Host CPU Usage Distribution
      • Cluster CPU Usage Statistics
    2. Click OK to save the selected monitoring metrics for display.

      Click Clear to cancel all the selected monitoring metrics in a batch.

  6. Export a monitoring report.

    1. Select a period. The options are as follows:
