## Frequently asked questions

### What OID is swap usage?

hrStorage used/size on the hrStorageVirtualMemory (or similarly labeled) row under 1.3.6.1.2.1.25.2.3.1, or UCD memTotalSwap/memAvailSwap at 1.3.6.1.4.1.2021.4.3 / .4.

### How do I monitor swap on Linux with SNMP?

Enable snmpd with HOST-RESOURCES (and UCD if you use it), walk storage descr, pick the swap row, compute used %, alert with duration. See steps above.

### Is high swap usage bad?

Depends. Steady low usage can be normal; rapid growth under load or swap full with no free RAM is bad. Context and rate matter.

### Does ostr.io monitor swap?

ostr.io can read swap name/capacity/usage via its external SNMPv2c metric set—keep allowlists tight.
