Analysis and control High cpu

Well from the snapshot, I could think of some daemon on the control plane is over utilizing the CPU.

And your tmm is under control, so i dont think its the traffic which would be causing it. Because when there's a huge traffic to be processed, the tmm daemon spike and goes above 80%. When this happens, the even cores where the tmm is running, starts to take use of the odd cores where the control processes are running.

But that's not the case in your picture, tmm is normal. So its not trying to use the odd cores.

I'd run the top command to check which process is consuming high CPU usage.

Followed by use the tmsh show sys proc-info, which would list all the processes running and the CPU utilization of it. This should give you a picture which process is consuming it more. Based on that, you can take an action if that process needs to be restarted or something else is going on with the box.

If its bigd daemon, its possible there is high L7 check monitoring happening, your box has hit the capacity limit. You might want to fix it by removing the ECDHE/DHE ciphers from the monitoring cipher suite.

There's lot to troubleshoot to find the fix, start with finding the process. Please keep us posted.
