Understanding %CPU Values in vFoglight
Unlike other data whose values represent a single point in time (when the data is
collected), each %cpu data value gathered by the Cartridge for Guest Process
Investigation is the average CPU utilization over time between successful data
collections. For example, if the configured sample interval is 30 seconds, a process's
%cpu utilization is an average of its utilization over the 30 second time period,
assuming two back-to-back collects were successful. For this reason, decreasing the
sample interval results in values that are real-time, making individual peaks and valleys
become more apparent, while increasing the sample interval does the opposite.
CPU Usage by Process
This view displays the cumulative CPU usage by processes over time. It shows the total
process load on a given virtual machine CPU. Mousing over the processes displays a
popup of the services.
