Well without blaming anyone, the easiest reason for this to cause would be a human mistake in interpreting the schedule downtime form (often happens with fixed/flexible) and by setting a wrong end date. When you were in the Downtime overview, did you take a look at the specified End Time column? What was written there before you clicked the delete icon? I suggest you go to your var/archives folder and check the logfile of April 1st for the external command, sth like this: [1333358804] EXTERNAL COMMAND: SCHEDULE_SVC_DOWNTIME;hostname;NTP;1333358695;1333365895;0;0;3600;Nagios Admin;test flexible [1333373670] EXTERNAL COMMAND: SCHEDULE_SVC_DOWNTIME;hostname;SSH;1333373648;1333384448;1;0;7200;Nagios Admin;test fixed These timestamps tell you WHEN the external command was launched, when the downtime starts and when the downtime ends. Also, note the 0 and 1 behind the end timestamp. Integer 0 indicates a flexible downtime, a 1 indicates a fixed scheduled downtime. To answer your question: Yes, after the end of the scheduled downtime, normal monitoring should have resumed. <div class="gmail_quote">On Mon, Apr 2, 2012 at 2:54 PM, Deborah Martin <<a href="mailto:Deborah.Martin@kognitio.com">Deborah.Martin@kognitio.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-GB"><div>Hi Claudio, Thanks for info. But I’m a little puzzled. I clarified the steps that were taken. It turns out that he didn’t use Flexible but instead used fixed. However, he’s sure that the dates were set to 1st April for the start and end date. So, surely once the date changed to the 2nd April, at the very least, normal monitoring should have resumed or is that not correct ? In fact I took your advice and removed the fixed downtime manually.

Otherwise the fixed dates are taken (Start Date, End Date). To remove a host or service from a scheduled downtime, click on "Downtime" in the left navigation. There you can delete the wanted entry. cheers<div>On Mon, Apr 2, 2012 at 10:42 AM, Deborah Martin <<a href="mailto:Deborah.Martin@kognitio.com" target="_blank">Deborah.Martin@kognitio.com</a>> wrote: <div><div>Hi, We use Nagios 3.2.0 on SLES 10 SP2 to monitor a few hundred services. Yesterday, we put a particular service into flexible downtime from around 7am to 2pm. However, it seems to still be stuck in flexible downtime so any alerts after 2pm haven’t been sent out. I’m not entirely sure why this is happening as I’ve used this before and never had any problems. Has anyone come across this before ? Is there a way to kick this service back into normal monitoring ?
