Cpu and memory usage

I have syslog configured on routers and switches, and I have configured alerts on my syslog server. The alerts depends on the

context of the line in syslog message. Let say, if the line contains word UPDOWN, then a mail will be sent to me stating that on a particular router an interface is down.

I want to do the same with CPU usage and memory usage.Unfortunatelly I do not know the content of syslog message when the CPU or memory usage is to high. I need that content to create a rule on my syslog server.

Does anybody know?

If you know the SNMP OID for CPU/memory usage, you can configure RMON or mini-RMON to alert on these variables crossing certain thresholds.

According to this link below, you can practically customize the text of RMON alerts before sending them to syslog and/or SNMP trap receiver:
