SNMP

SNMP, or Simple Network Management Protocol, is a widely used protocol for monitoring and managing network devices such as routers, switches, servers, and printers. It allows a central management system to query devices for performance data — like CPU usage, interface statistics, and error counts — and can also receive unsolicited alerts called traps when certain conditions occur. SNMP is a foundational tool in network operations centers (NOCs) for maintaining visibility across large infrastructure.
