I am really facing problem with downtimes. somtimes all downtimes for hosts are disappering and sending notifications. it is really pain to enter downtime again. is there any way to resolve this issue.
Are you restarting nagios and then you lose comments, downtime, etc or perhaps you have more than one nagios running?
then make absolutely sure they are all stoppped.
ps -ef|grep nagios
then start it up, make your downtime settings, and you should be good till the next reset.
when i restart server downtimes are disappearing
