How does CDM identify which are the top processes contributing to high CPU utilization

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)
• CA Unified Infrastructure Management On-Premise (Nimsoft / UIM)

Issue/Introduction

What exact command does the CDM probe use to see which is the "top process"

Example of alarm where this value is shown:
"CPU(Total) usage is now 95.61%, which exceeds the 95% monitoring threshold - top processes: [sqlservr.exe[1424]-(96.83%)"

Environment

Release:
Component: UIMCDM

Resolution

The methods the CDM probe uses for retrieving the top processes are the following:

• Unix and Linux: cdm uses the command: ps

   cdm uses this command to get the top processes-> /bin/ps -e -o pcpu,ppid,pid,args, --sort=-pcpu

• Windows: cdm uses Windows API's to fetch the processes list and their utilization
