Monitoring CPU Usage with SNMP

Can someone please tell me how to calculate the CPU usage from what one gets back from snmpwalk?

I have searched and dug through the internet and apparently, no one has the answer to this?

i can use snmpwalk to pull out relevant information about cpu. but i have no clue what values are to be taken seriously and how to calculate those values to get an accurate gauge of the CPU usage percentage on the server.

can someone please help me with this?

Have you reviewed the MIB documentation?
