Overview
...
up.time collects the configuration and performance data outlined in this article from Net-SNMP implementations. Additional performance data outside of this set can be collected using the SNMP service monitor with retained performance metrics.

List of Required Net-SNMP MIBs
...
All data that up.time gathers from Net-SNMP is based on the following MIB implementations:
...
\n\t- RFC 1213 - Management Information Base for Network Management of TCP/IP-based internets \n
Presents network interface information.
\n\t- UCD-SNMP-MIB \n
Presents general system state information.
\n\t- Host Resources MIB (RFC 2790) \n
Presents system performance data.
