I don't know how big your installation is, but if you have thousands of services or a distributed setup with passive checks and just enable ndo with the defaults, your ndo-database becomes very, very big. This can cause a slowdown of your db-server. And Nagios slows down too, because of the latency in sending the results to the DB. -Check the database size of the ndo-db -Check your Nagios service check latency, high service check latency COULD be caused by slowly responding DB -Check nagios.log and mysql.log to see if there are any errors -Don't always think Nagios doesn't come up again. If your ndo is not performing as it should, it takes a long time for Nagios to startup and recreate a status.dat-file which is used by the cgi's. I've had a case were it took up to 5 minutes before the status.dat was created after a Nagios startup, because of the ndo -Make sure you have the latest ndo-version Good luck, Frederik ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ 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
