## Frequently asked questions

### What is the OID for CPU usage?

HOST-RESOURCES hosts: 1.3.6.1.2.1.25.3.3.1.2. Walk the column. Gear with only enterprise MIBs is a different hunt.

### Is there a total CPU OID?

Not in HOST-RESOURCES. Average the per-core rows. Anyone selling a "total CPU OID" for this MIB is simplifying.

### What OID is load average?

UCD: 1.3.6.1.4.1.2021.10.1.3, usually three instances for 1 / 5 / 15 minutes.

### How do I read ssCpuRaw counters?

Two polls, subtract, divide components by total delta. Single sample = noise. If the leaf isn't there, walk the UCD branch and map names from the MIB on that host.
