Class NonBlockingNagiosPassiveCheckSender

java.lang.Object

com.googlecode.jsendnsca.NonBlockingNagiosPassiveCheckSender

All Implemented Interfaces:

PassiveCheckSender

public class NonBlockingNagiosPassiveCheckSender
extends Object
implements PassiveCheckSender

This sender does not block unlike the NagiosPassiveCheckSender. Instead it internally queues the passive check in an unbounded queue and has a single worker thread sending from the queue.

Any exceptions resulting from sending the passive check are output to standard error with a stack trace.

This sender is useful where you don't want to wait for the passive check to be sent and don't care if the sending fails

1.2
