Don't top-post. SNMP has two (three?) modes of operation. 1. Active polling - an SNMP client keeps polling the SNMP-enabled server or device for performance parameters. This is what software like Cacti, MRTG, Nagios etc. do. Depending on the MIBs implemented by the server or device, you can get a wealth of information about the performance and status. 2. Passive traps - an SNMP server on a monitoring station waits for "traps" generated by an SNMP-enabled device or server. Traps could be generated for a variety of reasons - a network link going down, a filesystem filling up, a hard disk going bad, a limit on number of simultaneous users reached - just about anything. The snmptrapd daemon on Linux can collect these traps and log them somewhere - and monitoring scripts can pick up these events and generate alerts. I am not sure if Nagios is capable of this, but I know that $$$ stuff like Netcool and HP Openview are. 3. SNMP Set operation - an SNMP client can be used to set operational parameters on an SNMP-enabled server or device. These parameters could be an IP address, memory limits or just about anything. I have seen some devices like printers whose only management interface is via SNMP. Others have multiple management interfaces, one of which is SNMP (others could be a CLI shell or a web interface).
