Predefined Dashboards

Describes all Grafana dashboards that are built in to theView for ClusterStor system

View for ClusterStor™ provides out-of-the-box custom Grafana dashboards that may be used to display ClusterStor and InfiniBand metrics. Some of these predefined dashboards can be accessed from the System Overview or the Jobs Table. All of the predefined dashboards are accessible from the Grafana Dashboard Selector.

Note: When navigating directly from a View for ClusterStor tile to a Grafana dashboard, the charts and metrics shown are specific to the ClusterStor system represented in that tile. Once in Grafana, however, using the Dashboard Selector to navigate to a different dashboard will change the scope of the data displayed, to all ClusterStor systems being monitored in View for ClusterStor. To maintain scope to a specific ClusterStor system when navigating within Grafana, use the links that appear when selecting the Details icons at the upper left of any panel in a dashboard.
