Viewing and Customizing Cluster Monitoring Metrics

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.

Cluster metrics are monitored periodically. The average historical monitoring interval is about 5 minutes.

• Scenario 1:
  • Method 1:
    1. Choose Clusters > Active Clusters and click a cluster name to access its details page.
    2. Click the Dashboard tab, you can view the cluster host health status statistics on the lower part of the displayed tab page.
    3. To view or export a report of other metrics, log in to Manager by referring to Accessing Manager.
    4. On the Manager page, view, customize, and export the node monitoring metric report by referring to Dashboard.
  • Method 2:
    1. Log in to the MRS console.
    2. Choose Clusters > Active Clusters and click a cluster name to access its details page.
    3. On the Dashboard tab page, click Click to synchronize next to IAM User Sync to synchronize IAM users.
    4. After the synchronization is complete, you can view the cluster monitoring metric report on the right of the page.
    5. In time range area, specify a period to view monitoring data. The options are as follows:
       • Last 1 hour
       • Last 3 hours
       • Last 12 hours
       • Last 24 hours
       • Recent 7 days
       • Recent 30 days
       • Customize: You can customize the period for viewing monitoring data.
    6. Customize a monitoring metric report.
       1. Click Customize and select monitoring metrics to display.
       2. Click OK to save the selected monitoring metrics for display.
          

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

    7. Export a monitoring report.
       1. Select a period.

          The options are as follows:

          Last 1 hour, Last 3 hours, Last 12 hours, Last 24 hours, Recent 7 days, Recent 30 days, or Customize (selection of a time range)

       2. Click Export. MRS will generate a report about the selected monitoring metrics in a specified time range. Save the report.
• Scenario 2 (applicable to MRS 3.x or later clusters)
  1. Log in to the MRS console.
  2. Choose Clusters > Active Clusters and click a cluster name to access its details page.
  3. On the Dashboard tab page, click Click to synchronize next to IAM User Sync to synchronize IAM users.
  4. After the synchronization is complete, you can view the cluster monitoring metric report on the right of the page.
  5. In time range area, specify a period to view monitoring data. The options are as follows:
     • Last 1 hour
     • Last 3 hours
     • Last 12 hours
     • Last 24 hours
     • Recent 7 days
     • Recent 30 days
     • Customize: You can customize the period for viewing monitoring data.
  6. Customize a monitoring metric report.
     1. Click Customize and select monitoring metrics to be displayed.
     2. Click OK to save the selected monitoring metrics for display.
        

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