"""
Provide CPU information related to the dstat process.
This plugin shows the CPU utilization for the dstat process itself,
including the user-space and system-space (kernel) utilization and
a total of both. On a system with one cpu and one core, the total
cputime is 1000ms. On a system with 2 cores the total is 2000ms.
It may help to vizualise the performance of Dstat and its selection
of plugins.
