Nagios Support Forum

Hi everybody. I'm experiencing an issue sind last Friday, that I can't solve.
Every checked service that is in either warning or critical state shows a negative time value in the "duration" field. Also there are no more notifications sent out for these events. The screenshot below shows this issue. The first warning is a "new" one with a duration of -19s. The second warning is older (older than last Friday) so it still shows the correct duration. Every new service in warning/critical state shows the negative duration...
Also, when I take a look at the advanced tab of this service, it shows that the last notification sent was 01/01/1970 (which is not correct).
However, if I look up this service in Nagios Core (via the "See this service in Nagios core" link), the correct state duration is shown...
Right now I don't know where to look for a solution...is there somebody who knows a way for fixing it?

EDIT:
I just realised that my NagiosXI webinterface is 7 hours behind my server time. When I have a look at some tables that have an "Last updated" below them, it reads: "Last Updated: 10/12/2012 00:43:02". When I logon to the NagiosXI Server using ssh and execute date it says "Mon Dec 10 07:44:00 CET 2012" (which is correct).

Thanks in advance,
Benjamin

Can you go to Admin -> System Profile and attach it here.

I am guessing you may not have synced times between the system time and the php.ini

you may also need to update the server timezone and time, instructions in this post

Hi,

thanks for the help. You were right, the Error was in the php.ini. There my system was on Chicago time-zone while the server itself runs on european time.
Thanks for the hint
