SNMP

Simple Network Management Protocol (SNMP) is a protocol used to manage performance and monitor network statistics. An SNMP network consists of devices, agents, and network managers. Information in SNMP is contained in Management Information Bases (MIBs) that consist of datapoints structured according to the Structure of Management Information (SMI).

To inspect the content of different MIBs various databases may be of assistance, for example MIB Browser.
