You're probably having check latency. Look at the "Performance Info" page... Active Service Check Latency should be near 0. If it's not you have a problem. Here's an overview or how scheduling works in Nagios: http://nagios.sourceforge.net/docs/2_0/checkscheduling.html Keep in mind that the following things will cause Nagios to stop processing commands until the external command returns: Host checks (performed on non-OK states, this can be solved in Nagios 3) Event handlers Performance data processing commands OCSP Commands - - It's not a good idea to avoid host checks so you'll want to make them return as fast as possible (using a well-tuned 1-ping check_icmp you can have ir always return within 1 second). - - Event handlers should fork before doing any work. - - Instead of using performance data processing commands you can have nagios write data to a file of fifo. See: http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2520.html;d=1 http://www.control-alt-del.org/code/NPDaemon/ - - Instead of using OCSP commands you can use the perfdata file to forward commands. See: http://www.nagioscommunity.org/wiki/index.php/OCP_Daemon IF you must use the perf/ocsp commands anyways make sure they fork before doing any work. You can also have a look at some other things you can tune: http://nagios.sourceforge.net/docs/2_0/tuning.html Thomas -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIFtqe6dZ+Kt5BchYRAsTMAKDU4tPvKkSgfXJbXYNe0PA7InH2YwCdGAv/ 8WnbJfCp4dzeD5vT4G3gl0M= =2g1n -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
