Portal Server 6 2005Q1 • Deployment Planning Guide

mpstat

The

mpstat

utility is a useful tool to monitor CPU utilization, especially with

multithreaded applications running on multiprocessor machines, which is a typical
configuration for enterprise solutions.

Use

mpstat

with an argument between 5 seconds to 10 seconds.

An interval that is smaller than 5 or 10 seconds might be more difficult to analyze.
A larger interval might provide a means of smoothing the data by removing spikes
that could mislead the result.
