The Host page in the KVM Data Explorer view shows the behavior of host-specific metrics.

To access this page, in the TrueSight console, select Capacity Views > Virtualization > KVM > Data Explorer. By default, the Host page is displayed.

From the Host filter, select the host that you want to view data for. In addition, you can other filtering options to filter the data according to your requirement. For more information, see Using filtering options in views in the TrueSight console. The metrics are categorized based on different profiles and are grouped under separate tabs. Click a tab to view the charts for that profile.

Process Profile

The Process Profile tab enables you to view the process-level data and workloads in the Data Explorer view for the systems that are being monitored by capacity agents. The process-level data displayed on this page is averaged according to the number of days selected in the filter for the Data Explorer view. The process-level data is displayed in the Process Profile tab if the process rollup is scheduled. To configure the aggregation of process-level data, see Aggregating process-level data for views.
