Desc: Information about SNMP and Network UPS Tools File: snmp.txt Date: 16 March 2003 Auth: Arnaud Quette or This document presents interactions between SNMP and Network UPS Tools. This work is mostly sponsored by: MGE UPS SYSTEMS There are two part in NUT for SNMP support: 1) the agent or server side An SNMP agent provides information for its hardware. In general, agents are embedded in SNMP card. This part has to be implemented as a Net-SNMP sub agent, acting as a NUT middleware (upsd level). Such software make a bridge between NUT data and SNMP, thus allowing to monitor, through SNMP, standard point to point UPSs (serial and USB). This is part of the "UPS Sub-Agent" project with Net-SNMP team. 2) the client side * Introduction An SNMP client communicates with an agent to acquire data. This part, which has to be a NUT driver, is implemented by snmp-ups. snmp-ups acts as a bridge from SNMP to NUT, thus allowing to monitor in NUT any SNMP Agent (embedded or on a host). The new snmp-ups driver now support multiple MIBS (SNMP structures declaration). For more information on snmp-ups, have a look at its manpage (man 8 snmp-ups). * Extending existing mib2nut information To be written... * Adding new mib2nut information To be written...
