I usa gearman as well, nice stuff. But it lacks of authentication so it's fairly unsecure. You can use mklivestatus as a broker to notify nagios status check to 3rd part applications.

For me, it was a good way to reduce memory and CPU, and it helped with check latencies. Although, the absolute best way to reduce check latencies for me has been to dump NDOUtils.

Re: [Nagios-users] use_large_installation_tweaks
I do not Like it. There are better strategies to reduce load. Try nrdp or nsca to distribute the load.
