Hi Yes you can check that in the nagios log files. Here an example: nagios-01-13-2012-00.log:[1326360203] HOST DOWNTIME ALERT: myhost;STARTED; Host has entered a period of scheduled downtime In the logs it's also shown when the host exits the scheduled downtime <div class="gmail_quote">On Thu, Mar 22, 2012 at 1:37 PM, Manish_Kmr <<a href="mailto:Manish_Kmr@mahindrasatyam.com">Manish_Kmr@mahindrasatyam.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div link="blue" vlink="purple" lang="EN-US"> <div> Hi List, For a particular server there was a complaint that even it was in scheduled downtime for some specific period on a particular past day, it sent a host down notification and the ticket has been raised for the same in the integrated ticketing tool. Now I need to check somehow in the logs, is that server was really put into downtime on that day for that specific duration.
