## Frequently asked questions

### What can SNMP monitor?

CPU, memory, disk, swap, interfaces, uptime, processes, hardware sensors, UPS, environmental probes—anything the agent exposes via OIDs. See the table above and sensors/all.

### How do I set up SNMP monitoring?

Enable and harden the agent, allow UDP 161 from pollers, verify with snmpwalk, then attach an NMS or external poller and define alerts. Setup has OS paths.

### Is SNMP good for server monitoring?

Yes for OS/hardware metrics with a light agent footprint. Pair with app metrics elsewhere. Server hub: server monitoring.

### What is external SNMP monitoring?

Polling the agent from outside your network/site so a local NMS outage doesn't blind you. Still needs snmpd (or equivalent) on the host.
