Re: [Nagios-users] R: use_large_installation_tweaks
I've just turned on this use_large_installation_tweaks option today. It reduces the check latency significantly. Other than that, not so much. I had tried using mod_gearman as well. It's a very nice addition to distribute loads to other servers, but I had a hard time doing configuration, deciding the best number of workers etc. On Tue, Apr 10, 2012 at 12:24 AM, Marco Borsani wrote: > Very interesting. > > I don't understand french a lot are there the steps to follow for the > optimization ? > > Regards > Marco > > -Messaggio originale- > Da: Alexandre Bray [mailto:in...@opendoc.net] > Inviato: sabato 7 aprile 2012 18:50 > A: Nagios Users List > Oggetto: Re: [Nagios-users] use_large_installation_tweaks > > hello, > > Here are some tests with the option use_large_installation_tweaks.

I have one server with NSCA, for accepting passive checks from 80 hosts more or less. The next step is replicate the same configuration in another server, for example for the access of datacenters operators aroud Central America, if the server is attacked, only crash a mirror and no the original server. My question is... I use send_nsca and nsclient++, Can Merlin accept packages from these clients? Or a can only install Merlin from send the package of checks from the original server to the mirror?

It will give Nagios a little less to do, so that you can give it a little more to do and still stay the same, or so that the hardware can cope with the load you're throwing at it. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Better than sec?

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.

[Nagios-users] R: use_large_installation_tweaks
We don't use NDOutils. We have two kind of performance problem: 1) day-by-day - some Nagios servers have many services configured that can be heavy for the HW 2) trouble with main Nagios server - the other Nagios servers that send to the main the passive results (via nsca) , due to the stop of the main server become very slow Marco -Messaggio originale- Da: C.
