Overview
Windows collects a range of performance metrics from the various system components. Each component amalgamates the performance metrics into a performance object. The up.time Windows agent collects the following metrics from the performance objects on a Windows system:
...
...
Each set of performance metrics is averaged over an interval of one second.
...
CPU
...
The up.time agent outputs the metrics listed below for the entire system, and combines and averages all CPU statistics.
...

\n\t| The percentage of time that the processor spends in user mode (a processing mode for applications and subsystems). |
\n\t \n \n \n\t \n\t| The percentage of time that the processor in privileged mode, in which it has direct access to hardware and memory. |
