Run As Account Credentials Distribution (More Secure option)

Hi

I am bit confused "in which scenarios, we should distribute Run as Account credentials to Resource Pool".

I mean we have bydefault three Resource Pools (AD Assignment, All Management Servers and Notification Resource Pool) in SCOM and we create two more pools basically for Network Device Monitoring and Unix/Linux Monitoring.

Lets take an example- I have to discover and monitor Unix computers and Network devices. So I have configured one Run As Account for Unix Monitoring and one SNMP v2 Run as account for Network Device Monitoring. So in these both scenarios, on which basis I should distribute these Run as Account credentials and to which computers/resource pools?

Please let me know if anybody know about this.

Thanks in advance.
