about system health rules

[entrylevel]

i'm not familiar with openview, may i ask if i want to
monitor system performance say cpu, is there build-in
health rule for cpu in openview or i have to define it all by myself, for example, Alert alarm is generated when CPU
exceeds 1 swap-out, 10 page-ins, and 10 page-outs per
second, that type of thing.

and by the way, any suggestion where can i find these
rules for performance tuning?

thanks a lot for everything.
