Cirrocumulushigh cpu usage independent from Traffic
Hello, we've recognised since a few weeks every day for about 4 hours from 9 to 13 very high cpu-usage on Control-Plane and Analysis-Plane. Overall concurrent Client-side connections between 1200 a...
Hi kgaigl ,
could you please have a look on ASM obfuscator Articles :

https://my.f5.com/manage/s/article/K02827102If you realised that high Control plan CPU due to ASM Obfuscation process , that's not an issue or can cause a negative impact :
Below Article from the first KB I sent above " https://my.f5.com/manage/s/article/K12201682 "
- The obfuscation process consumes available resources with a lower priority. If more important processes need CPU/Memory the obfuscation is de-prioritized or will wait until resources are available.
In addition to what Mohamed_Ahmed_Kansoh mentioned, if you're provisioning AVR module, it might cause high CPU utilization depending on how many virtual servers are using the analytics profile.
Also, the odd and even cores can be extracted from the CPU graph on ihealth portal. you can generate a new QKVIEW file, import it to any of your F5 accounts and navigate to "graphs" section. then, select "Blade 0 CPU Usage By Core" and filter by the even cores as Kansoh mentioned.
you can also try rebooting the device and check if the same CPU utilization occurring or not, because sometimes cleaning up files, and processes might hang out.
