Issue/Introduction

Noticing High CPU utilization 99-100% on Clarity, how to determine what is the cause of this?

Environment

Release : Any

Resolution

There is no way to determine what caused the problem in the past. If this happens again:

• Note which node has the problem
• Connect to it, note the CPU/RAM taken
• Check which process takes high CPU - app, bg or other
• Collect app-ca and app-system for app and bg-ca bg-system for bg (depending on affected service)
• If app/bg, collect the heap dump on the affected service as per: Manual heap dump for application hanging or slow performance
• Also collect thread dumps on the affected service as per Troubleshooting Clarity with thread dumps
• Provide the heap dump, logs and thread dumps to Broadcom Support for review.
• Note any unusual activity happening at this time as well such as large imports, data extracts etc. and provide this information as well
