Overview
\n \nup.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.
\n \nList of Required Net-SNMP MIBs
\n \nAll data that up.time gathers from Net-SNMP is based on the following MIB implementations:
\n-
\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.
