Overview
Uptime Infrastructure Monitor 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 Uptime Infrastructure Monitor 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.
