nagios-merlin is an eventbroker module / daemon pair which acts as an event transport layer. Transporting events between multiple Nagios instances allows building loadbalanced, redundant and distributed monitoring solutions quite easily.

Lately, the merlin daemon has been given capabilities to insert transported events into a database, using libdbi to provide flexibility in choice of database solution. This, combined with the distributed and loadbalanced nature of Merlin, provides the foundation for building a monitoring solution that scales up to truly huge networks.

This software is running on op5 production servers since March 2009. We consider it "stable beta software" (meaning we've determined it doesn't crash or do weird things, but database schema, API's and protocols are still subject to change without notice).

The install-merlin.sh script should make it relatively simple to install and run merlin from source. Please refer to the README file for additional information.
