Overview

The SAM Linux CPU Monitoring - Perl template and it shows the CPU information or values as incorrect (or does not change between polling).

Product section

Server Application Monitor

Resolution

The vmstat (which PERL uses to pull the information) does not report the actual value of the CPU, therefore the values are not real time. It reports instead a rolling average. This is by design and limitation within vmstat and not of SAM.
