Mod Gearman

Mod_Gearman is an easy way of distributing active Naemon checks across your network and increasing Naemon scalability.

It can even help to reduce the load on a single Naemon host, because it’s much smaller and more efficient at executing checks.

It consists of three parts:

There is a NEB module which resides in the Naemon core and adds service checks, host checks and event handlers to a Gearman queue.
One or more worker clients execute the checks. Workers can be configured to run checks only for specific hostgroups or servicegroups. There is a (deprecated) worker included. The new worker can be found here.
You also need at least one Gearman Job Server running.

Features

Reduce the load on your central Naemon machine
Make Naemon scalable up to thousands of checks per second
Easy distributed setups without configuration overhead
Real load balancing across all workers
Real failover for redundant workers
Embedded Perl support for very fast execution of Perl scripts
Fast transport of passive check results with included tools like send_gearman and send_multi

Mod Gearman and the new Go worker are included in OMD.
