View totals across processes and nodes

The metric graphs show the statistical distribution of the metric across ranks or compute nodes (depending on the metric). So, for example, the Nodes power usage metric graph shows the statistical distribution of power usage of the compute nodes.

If you hover the mouse over the name of a metric to the left side of the graph, a tooltip will display additional summary information. The tooltip will show you the Minimum, Maximum, and Mean of the metric across time and ranks or nodes.

For metrics which are not percentages, the tooltip will also show the peak sum across ranks / nodes. For example, the Maximum ( $\Sigma$ all nodes) line in the tooltip for Nodes power usage shows the peak power usage summed across all compute nodes. This does not include power used by other components, for example, network switches.

For some metrics which are rates (for example, Lustre read transfer) the tooltip will also show the cumulative total across all ranks / nodes, for example, Lustre bytes read ( $\Sigma$ all nodes).
