## Frequently asked questions

### What OID shows logged-in users?

hrSystemNumUsers 1.3.6.1.2.1.25.1.5.0 — a count of active sessions, not a user list.

### Can SNMP show who is logged in?

Not via this object. HOST-RESOURCES gives the count only. Use auth logs for identity.

### How do I alert on login spikes?

Baseline normal session counts; alert when the count stays above a threshold or jumps sharply for several polls; investigate with logs.

### Does external monitoring see sessions?

Services that poll this OID—e.g. ostr.io’s session metric—see the same count the agent exposes, nothing more.
