What is SNMP (Simple Network Management Protocol)?

A protocol for monitoring and managing network devices like routers, switches, servers, and printers remotely.

SNMP collects information from network devices using a manager-agent model. Agents run on devices, exposing data (CPU usage, interface traffic, error counts) via OIDs (Object Identifiers) organized in MIBs (Management Information Bases).

Operations include GET (read value), SET (change value), and TRAP (unsolicited alert). SNMPv3 adds encryption and authentication. SNMP is widely used in network monitoring tools like Nagios, Zabbix, and PRTG.
