How can I calculate CPU load from SNMP raw values?
The following formula can be used to calculate CPU usage:-100 * (ssCpuRawUser.0 + ssCpuRawNice.0 + ssCpuRawSystem.0) / (ssCpuRawUser.0 + ssCpuRawNice.0 + ssCpuRawSystem.0 + ssCpuRawIdle.0 + ssCpuRawWait.0)The raw values are cumulative and to calculate statistics or plot a chart between time t1 and t2 we can use delta between t1 and t2 for each of these counters in the formula. The relevant OIDs are:-UCD-SNMP-MIB::ssCpuRawUser.0OID: .1.3.6.1.4.1.2021.11.50.0UCD-SNMP-MIB::ssCpuRawNice.0OID: .1.3.6.1.4.1.2021.11.51.0UCD-SNMP-MIB::ssCpuRawSystem.0OID: .1.3.6.1.4.1.2021.11.52.0UCD-SNMP-MIB::ssCpuRawIdle.0OID: .1.3.6.1.4.1.2021.11.53.0UCD-SNMP-MIB::ssCpuRawWait.0OID: .1.3.6.1.4.1.2021.11.54.0Note:- Certain SNMP tools may use deprecated OID 'UCD-SNMP-MIB::ssCpuIdle.0' (.1.3.6.1.4.1.2021.11.11.0) resulting in wrong CPU load calculation.
