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:
- RFC 1213 - Management Information Base for Network Management of TCP/IP-based internets
Presents network interface information.
- UCD-SNMP-MIB
Presents general system state information.
- Host Resources MIB (RFC 2790)
Presents system performance data.
