On Linux agents, CPU statistics are averaged over one second at the time of agent polling. This may occasionally produce results that are not entirely consistent with output from other tools such as vmstat.

To improve the accuracy of the Linux agent, increase the sar time interval within the agent from 1 second to 10 seconds by editing the /opt/uptime-agent/bin/perfparse.sh or the /opt/SPYNuptm/bin/perfparse.sh file on the agent system.

Look for the following text: SARBIN -urWqR 1.

Change the 1 to a 10 and save the file. After this change, all CPU stats will be averaged over 10 seconds at the time of polling instead of 1 second.
