Any chance your system time got thrown off due to DST or a shutdown of an ESX server (if it's a VM)?

You can make sure your system time is up to date and synced by the following:

Time issues were one of the first few things I looked at after the usual stuff and I didnt see any issues. I will look into the ESX server issue. So what Im seeing this morning is that every thing started checking again at 11:PM last night as that was the "next check". Essentially, graphing was never down. it was those checks that got screwed up. Its last check was Sunday night and its next check was Monday night so there was nothing to graph! Very confusing how every check could have been changed to one time........

I checked with the VM guys and they reported no ESX/Server issues for Sunday night around that time. Im still curious tho, is there a way to schedule an immediate check for multiple devices? If that "next check" date/time gets set for something farther in the future how do I get around it?

If you set the following directive in your /usr/local/nagios/etc/nagios.cfg
And then run: Nagios will reschedule all of it's checks. Otherwise, a way you can mass schedule an immediate check is with the latest version of the Mass Acknowledgment Component.

Awesome! I think either one of those WOULD do the trick! I appreciate all of your guidance!
