How to setup scalefactor with a multi cpu OS and CA WA System Agent?

Products

• Workload Automation Agent
• DSERIES- SERVER
• CA Workload Automation DE - System Agent (dSeries)

Issue/Introduction

Use objmon.cpu.scalefactor parameter as a scale factor to multiply the load averages of a CPU and allow WA System Agent, when processing a CPU_MON monitor job, to express the load average as a percentage. The default is 100.

 

Environment

Release: CA WA Agent 11.3/11.4/11.5
OS : UNIX/Linux

Resolution

The scale factor based on the number of processors in the OS. The reported usage would be the sum of all the CPUs added together. 

Here are some examples of the values for scalefactor in multi cpu unix boxes:

For OS with 2 CPUs, setup 

objmon.cpu.scalefactor=50

For 4 CPUs:

objmon.cpu.scalefactor=25
