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. If you haven't already, please review How to add a Net-SNMP enabled server.
List of required Net-SNMP MIBs
All data that UIM 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.
System Configuration Data
