RE: [nsp] what uses all the cpu cycles

Your MSFC is switching a bunch of packets (64%), and then you have
somewhere around 30% doing process level things. The output of the
"show proc cpu" will tell you which set of processes are causing that
30% load (which sounds a little high).

I'd be happy to take a look at what you have captured so far if you
want.

Subject: [nsp] what uses all the cpu cycles

Greetings,

Several times a day two of my MSFC2s/6509s show high CPU usage:

  CPU utilization for five seconds: 91%/64%; one minute: 89%; five
minutes: 86%

One MSFC2 serves mostly as an HSRP standby for the other.

I captured the output of the commands below during low CPU and during
high CPU but was unable to figure out what contributed to the high CPU.

show processes cpu
show interfaces
show interfaces switching
show interfaces stat
show align
show version
show log

If someone on the list is experienced in analyzing the CPU usage and is
willing to help, I can send the stats to him/her.
