Re: CPU Process Question

If it's intermittent high CPU (it always is, isn't it?) this EEM
script will write a file to your flash with helpful commands:

Sample Event Manager Script to automatically collect info when the
high CPU is observed:

event manager applet capture_cpu_spike
  event snmp oid 1.3.6.1.4.1.9.2.1.56 get-type next entry-op ge
entry-val 70 exit-time 10 poll-interval 1
  action 1.0 syslog msg "CPU Utilization is high"
  action 2.0 cli command "enable"
  action 3.0 cli command "show process cpu sort | append flash:cpu.log"
  action 4.0 cli command "show clock | append flash:cpu.log"
!
event manager session cli username <username>

Just watch out for sending too much to your flash, as it can make the
problem worse. Other standard EEM warnings apply. This particular
script kicks off at 70%.
