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.


    Presents general system state information.

  • Host Resources MIB (RFC 2790)

    Presents system performance data.
