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.

    • \n
