Issue:
Affects Release version(s): 5

Error Message :
None

Patch level detected:Sysload Agent for Unix
Product Version: Sysload 5.8.0

Description :The calculation of physc per process seems not to be coherent with the total physc used by the LPAR
Environment:
OS: IBM AIX
OS Version: all AIX
Cause:
Cause type:
By design
Root Cause: This is expected behaviour of the agent for AIX.
Resolution:
Sysload stats are coherent with the topas stats, short life processes are not seen either in topas but they contribute to the physc of the system.
