Brocade DCX8510 CPU utilisation peaks

Hello
We observe daily peaks (up to 100%) of cpu utilisation on cp blade during the night.
Is it possible somehow to find out which process causes it  apart from logging in to the switch and run top command?

Re: Brocade DCX8510 CPU utilisation peaks

A few quick questions:

 

1- are you seeing these through MAPS alerts?

 

2- other than the alerts, are these causing any problems that you are aware of?

 

3- you mentioned not wanting/able to run 'top' command. Is this because it will violate an internal/external/customer SLA or security policy? 

 

4- do you have full access to the 'root' account? 

 

Thanks.

Hello. Could you please check below command? It will show the list of top processes ordered by CPU usage in descending order.

 

ps -eo pid,ppid,cmd,%cpu --sort=-%cpu | head

 

Example-

EDCX8510-8:FID128> ps -eo pid,ppid,cmd,%cpu --sort=-%cpu | head
PID PPID CMD %CPU
4583 2 [SW_TIMER_TASK_0] 15.2
4563 4560 /fabos/webtools/htdocs/0.we 12.3
4230 2214 esmd -S fcsw 8.9
4229 2214 cald -S fcsw 7.0
4227 2214 mdd -S fcsw 2.9
10701 2 [bcmCNTR.2] 2.9
11078 2 [bcmCNTR.3] 2.9
4390 2 [bcmCNTR.1] 2.9
5790 2 [bcmCNTR.0] 2.9

PID PPID CMD %CPU
