Can you post your nagios.cfg with comments and blank lines stripped out? please do strip out comments and blank lines so that it is not a huge post :). We did a small patch to remove a sleep time that nagios does between non-runnable events, i did post it to the nagios developer's list, it boosted our performance at higher polling density noticably. Right now we get about 2500 active host checks / 12500 active service checks per nagios node with all checks completed every 5 minutes for services and host checks running every 10 minutes. - Max ------------------------------------------------------------------------------ _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
