[Nagios-users] Nagios disfunctional , perhaps due to time change ?
- Nagios 3.2.0 --- - This morning, I find nagios stopped death in it's tracks. Single daemon running, servcie and host checks are no longer executed. Stopping and restarting NAGIOS does not help. How can I remedy this ? We left DST in Europe. Can this be due to a time change ? All hints welcomed ! Marc. -- Come build with us!

Re: [Nagios-users] Nagios disfunctional , perhaps due to time change ?
Hi, This happened to us as well. All services had been scheduled to execute at 11 PM today. The quick fix we used was to stop Nagios, move the objects.cache and retention.dat files and then start it back up again. All acknowledgements etc. were lost but we needed to get back up again soon. Note that this only happened on our 3.2.0 install, another 3.0.6 was fine. I'm still investigating what happened, but the above should let you get it back up again.

Re: [Nagios-users] Nagios disfunctional , perhaps due to time change ?
Same here! I spent some time last night figuring out what happended. I ended up downgrading to 3.0.6. I also had to remove the retention.dat. The queue looked really strange. All hosts at top and then services, all at times on the hour (like 23:00:00 today). Reschedule them did not help. I'll stay on 3.0.6 till someone finds an explanation ... :-) Regards, /Marcus On 10/26 09:21, Martin Melin wrote: > Hi, > > This happened to us as well.

This can be solved with issue the following error. service nagios stop; now=$(date +%s); sed -i "s/^next_check=.*/next_check=$now/" /usr/local/nagios/var/status.sav; service nagios start this will only work if: 1. you can issue command 'service' :) 2. you have it installed to /usr/local/nagios On Mon, Oct 26, 2009 at 10:09 AM, Marcus Rejås wrote: > Same here! > > I spent some time last night figuring out what happended.

OK, but have you saw this bug afer changing the system clock ? I have saw thsi issue about 13 hours later. I am not sure about the relation between the nagios problem and have detected a similar error 2 weeks ago. 1 week ago I have upgraded my Nagios 3.0 installation to a 3.2 version.

When we run into this in the US, what is the easiest way to correct the issue if we don't need to retain and downtime, acts or any status data. Is there a file or two that just needs to be deleted?

Re: [Nagios-users] Nagios disfunctional , perhaps due to time change ?
Hello, Same bug. Last sunday, in France, Daylight saving time ends so clocks retreat from 03:00 CEST to 02:00 CET. Today, I see that many checks of my nagios server have problems : next check is scheduled today at 11:00pm but, in the config files, the check interval is set to 5 minutes. More over, last week, it works as expected with checks every 5 minutes. Mark Elsen a écrit : > - Nagios 3.2.0 > --- > > - This morning, I find nagios stopped death in it's tracks.

If our configuration is not using daytime offset, are we still affected by this bug. Nagios version 3.2.0 Please advise on this.

Affected are all Nagios versions >= 3.1.0. I could reproduce it here: if the patch above is backed out, the scheduling behaves correctly. I've managed to get a libtap test case with the failure now. As you correctly say, removing the t->tm_isdst=-1 in utils.c fixes it. However, the fact it works is lucky. The check is that the scheduled time is between a date_range_start and a date_range_end. This date_range_end is based on the timeperiod definitions. However, an end point of 00:00 is calculated as 24*60*60. Obviously, this is wrong on the day that the clocks go back as there are 25 hours in that day. So removing tm_isdst gets the calculation for the epoch time wrong, but that luckily works because the time falls within the 24 hour period. I've applied the patch to remove that single tm_isdst. Tests are also added now, for this specific issue. Long term, I think it is correct that the isdst flag be set, but there are other problems that are lurking in the code, such as the calculation for the next appropriate time. Any comments?
