Update the OpenTSDB Data Source For Grafana

Grafana connects to a single OpenTSDB node to read metrics. If Grafana cannot read the metrics because an OpenTSDB node has failed, you must configure Grafana to connect to a different OpenTSDB node.

About this task

NOTE The OpenTSDB node that Grafana connects to by default is determined by the first OpenTSDB node that was specified when the cluster was configured to use metrics monitoring.

Procedure

  1. Use one of the following methods to launch the Grafana user interface:
    • From the Control System, select the Grafana view. After you select the Grafana view, you might also need to select the Pop-out page into a tab option.
    • From a web browser, launch the following URL: http://<IPaddressOfGrafanaNode>:3000
  2. Click the Grafana icon in the upper left corner to toggle the side-menu bar.
  3. Select Data Sources from the menu.
  4. Click the MapRMonitoringOpenTSDB data source.
