Overload Cpu
Hello everyone,
i have been migrating the configuration beetwen F5 device from old device to another one i2600 ver 16.1.4.
I have verified that the device does not responding as expected and i have verified by using graphic the use of it, in a short in some hours of the day it use a lot of cpu and, after 06:00 p.m. the situation is normal.
You need to know thatm at the moment, the device does not processing traffic, i have configured only the high availability and management ip.
I have attached the creen about the use of the cpu and the script that are inclued in the crontab.
Someone could help me to fix the problem ?
Many thanks in advanced for your attention.
Rgds,
that could be the issue. definatly something to look at.
i would lean more towards using the top command to find out what is causing the issue.
With ASM - i would further be concerned about spinning disks vs. SSD which will show up as a 'wa' in the top stastics.PhatANhappy mentioned about too small resources and that this is control plane utlization not data plane and the ''top'' will review if it is the bug or another process. About the ''wa'' that is something I would also renember from this discussion.
About the Analysis plane this in most cases is the ASM/AWAF policy builder learning, so also better also switch it off The BIG-IP ASM device shows high CPU usage in Analysis plane (f5.com) but this is could be still related to not enough resources for LTM + AWAF.
