DNX Version 0.15 Released!

[John Calcote]

We're pleased to announce the release of the Distributed Nagios
eXecutor (DNX) version 0.15.

DNX is a modular extension of Nagios that offloads a significant
portion of the work normally done by Nagios to a distributed network
of remote hosts. DNX worker nodes execute the DNX client as a daemon
service. DNX clients register requests for work with the DNX server
module. The DNX server module is a Nagios NEB (Nagios Event Broker)
plugin module, which registers an event handler for all service
checks. During the event, the DNX NEB module indicates to Nagios that
it will handle the service check. It sends the check command to a
registered worker node. A background thread awaits result information,
which the NEB module then posts to the Nagios results queue. The DNX
NEB module ensures that work is distributed fairly and evenly among
the registered DNX client hosts.

It's been 4 months since the release of the last version (0.13) of
DNX. The following is an excerpt from the DNX NEWS file for version
0.15:
