The Nagios Service Check Acceptor (NSCA) is used to send service check results to a central Nagios server. This consists of the "nsca" daemon which runs on the main Nagios server and accepts results and the "send_nsca" client which is used to send results to the server.

This module implements an alternative "event dispatcher" for Net::SNMP, using AnyEvent as a backend. It integrates Net::SNMP into AnyEvent: You can make non-blocking Net::SNMP calls and as long as other parts of your program also use AnyEvent (or some event loop supported by AnyEvent) and they will run in parallel.
