Provide more information related to the dstat process.
The dstat cputime is the total cputime dstat requires per second. 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.
