The Simple Network Management Protocol is the protocol governing network management and monitoring of network devices and their functions. This monitor queries the SNMP device and tries to match the expected returned value.
In order to select the appropriate object in the MIB tree, you need to be familiar with the MIB names for the SNMP objects you want to monitor. For more information, see RFC 1213.
Example A. Suppose you want to monitor the volume of data going out through your router, you'd select ifOutOctets in the MIB object tree, thus inserting 188.8.131.52.184.108.40.206.1.16 in the MIB box.
Example B. Suppose you are interested in the operating status value of a port on your router; in this case, you would select ifOperStatus, thus inserting 220.127.116.11.18.104.22.168.1.8 in the MIB box.
Example C. Suppose you're interested in the errors on a port on your router; in this case you'd select ifInErrors, thus inserting 22.214.171.124.126.96.36.199.1.14 in the MIB box.
