I think mod_gearman is what you're looking for: <a href="http://labs.consol.de/lang/en/nagios/mod-gearman/">http://labs.consol.de/lang/en/nagios/mod-gearman/</a> Also 1400 checks is not that huge of a setup. You can also specify check_interval for certain checks which don't need to be executed every now and then (e.g. Disk Space Utilization, HDD Smart Status or validity of SSL certificates). This can help a lot to bring down the load on your Nagios server. <div class="gmail_quote">On Sun, Jun 10, 2012 at 2:28 PM, Brandino Andreas <<a href="mailto:ampranti@gmail.com" target="_blank">ampranti@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all, my nagios installation has currently 400+ hosts and around 1400 checks. As the server load grows, delays are appearing. Is any way to move a part of active checks to a second nagios server? And in that case how will these two nagios servers exchange data? If this is feasible can you point me to some documentation?
