Using the SNMP Monitor

The Simple Network Management Protocol (SNMP) is the protocol responsible for governing network management. In this monitor, WhatsUp Gold utilizes SNMP to gather specific information about the functions of SNMP-enabled network devices by querying a device to verify that it returns an expected value. Depending on the state you choose, the monitor is considered either Up or Down according to the returned value.
