Hi team,
We have a situation where every now an then the CPU is increased considerably, and never recovers, until the consumption gets to 100%. To give you an example, if the first day of month the CPU is OK, one week later all in a sudden the CPU gets a peak and increases to 40%, and stays like that for some days. Then two weeks later the CPU suffers another peak and increases from 40% to 75%... and so on until by the end of the month the CPU gets to 100% and then we are forced to reboot.
I have noticed that the problematic process is the WAS portal where the web application is hosted, and we have an App agent enabled there. In order to find the root cause, I have created a bunch of Business Transactions, so I could see which ones are CPU expensive. Unfortunately this didnt help, and couldn't get any connection between these CPU expensive BTs, and the CPU peaks.
Do you know any more effective method to troubleshoot these CPU issues?
I have found the following article: https://community.appdynamics.com/t5/Knowledge-Base/How-do-I-troubleshoot-high-CPU-usage/ta-p/23266
But this is not exactly our case because the CPU peaks don't occur just when the agent is enabled.
Thanks!
