service which consuming CPU consumption more

Hi,

We are using wM 8.0, few queries i want to post here for getting more info on OFI:

  1. Is there any way to find out which service is consuming CPU more at OFI, is there any KPI to find out this?

  2. KPI run time by IS service ?

  3. Is it possible to modify the standard email alerts from optimizer by placing our own text? if possible how can we edit optimizer standard email alerts ?

Any info provided will be gr8 help for us.

Regards,
Vikram
