Displaying charts and graphs

The Nodes page contains the graphs and charts you should access regularly to monitor attributes such as storage capacity and throughput. In some cases, especially when working with technical support, you can use the Support > Tools > Grid Topology page to access additional charts.

Before you begin

You must be signed in to the Grid Manager using a supported browser.

Procedure

  1. Select Nodes. Then, select a node, a site, or the entire grid.
  2. Select the tab for which you want to view information.
    Some tabs include one or more Grafana charts, which are used to plot the values of Prometheus metrics over time. For example, the Nodes > Hardware tab for a node includes two Grafana charts.
