Make sure you understand the underlying design of distributed nagios setup. Obssessive-Compulsive (ocsp) command need to be correctly configurated on nagios slave. <div class="gmail_quote">2010/5/14 Sérgio Afonso <<a href="mailto:sergioafonsojr@gmail.com">sergioafonsojr@gmail.com</a>> <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hello Marcel, My nagios version is 3.2.0. About my command_check_interval I couldn't understand very well what you mean. My command_check_interval is set to -1 Rgs, Sérgio. <div><div></div><div class="h5"> On Fri, May 14, 2010 at 1:50 PM, Marcel <<a href="mailto:mitsuto@gmail.com">mitsuto@gmail.com</a>> wrote: > With only 150 services, it should not delay that much nor stops execution of > the main process. > Please check you main nagios.cfg file and look for command_check_interval, > if the value attributed to that variable isn't "-1" then there is your > problem. > > Also, which nagios version are you running? > > > On Fri, May 14, 2010 at 2:28 PM, Trisha Hoang <<a href="mailto:trisha@rockyou.com">trisha@rockyou.com</a>> wrote: >> >> Hi Sergio, >> Some of the directives I found helpful for our MASTER server are listed >> below. >> >> Since status.dat and nagios.cmd are disk bound, put them on ramdisk will >> be faster. >> status_file=/mnt/ramdisk/status.dat >> command_file=/mnt/ramdisk/nagios.cmd >> >> I don't think aggressive_host_checking is needed as nagios checks for host >> when a service is in error anyway. >> use_aggressive_host_checking=0 >> check_host_freshness=0 >> >> Service freshness is important as the MASTER tends to process passive >> checks much slower so the services may go stale.
