# SNMP Process OIDs: hrSWRunTable & hrSystemProcesses Reference

The SNMP OIDs for processes — hrSystemProcesses count, hrSWRunTable name/status, and hrSWRunPerfTable CPU/memory — with a snmpwalk example.

## Frequently asked questions

### What OID lists running processes?

The hrSWRunTable at 1.3.6.1.2.1.25.4.2.1. Walk hrSWRunName (.2) for process names, hrSWRunPath (.4) for the executable path, and hrSWRunStatus (.7) for run state. Each row is one running program, indexed by a run-index.

### What OID is the process count?

hrSystemProcesses at 1.3.6.1.2.1.25.1.6.0 — a Gauge32 with the current number of processes. It's a scalar (note the trailing .0), useful as a cheap sanity signal for fork storms or a stuck service, though it can't tell you which process.

### What does hrSWRunStatus mean?

It's the run-state enum in hrSWRunTable at 1.3.6.1.2.1.25.4.2.1.7: running(1), runnable(2), notRunnable(3), invalid(4). For a health check, running or runnable is normal; a process that's expected but missing from the table, or shown invalid, is the failure to alert on.

### How do I get per-process CPU?

Read hrSWRunPerfCPU at 1.3.6.1.2.1.25.5.1.1.1 for the row — it's cumulative CPU time in centiseconds, so sample twice and diff for a rate. Memory is hrSWRunPerfMem (.2) in kilobytes. Both share the hrSWRunTable index, so join on it to name the process.
