Nagios Support Forum

Hello...

maybe I have a problem and I hope you can help me.

I am using nagios xi for evaluating a new monitoring system for our company. All is working fine except one "question mark" on the "XI System Component Status" view.

The entry "Event Data" got a question mark beside it and when you hover the mouse over the icon it says: "Last EventData Transfers was 1h 0m 44s ago".

What does this mean?

That is an indication that Nagios XI is not currently seeing monitoring/status data being sent from Nagios Core (the monitoring engine) to NDOUtils (one of the database backends).

If things are off by an hour constantly, it could be that apache/mysql thinks the time is different than Nagios Core. This could have happened after the recent DST time switch. To attempt to fix this, do the following:

1. Stop NDO2DB, Nagios Core, and Apache:

/etc/init.d/nagios stop
/etc/init.d/ndo2db stop
/etc/init.d/httpd stop

2. Verify the system time:

date

3. Start the services back up:

/etc/init.d/httpd start
/etc/init.d/ndo2db start
/etc/init.d/nagios start

Thank you for the quick response!

No success. But I´ve recently changed the timezone for the server to Europe/Berlin. Could it be possible, that Apache and ndo are running with a different time? There is still a one-hour-delay.

I´ve set the timezone under etc/sysconfig/clock:

ZONE="Europe/Berlin"
UTC=false
ARC=false

And I´ve made a symbolic link usr/share/timzones.../Europe/Berlin/ ---> etc/localtime

My date is correct:

Thu Nov 18 15:28:20 CET 2010

Any further help?

Got it!

I found out, that the TZ-Variable must also be set before the mysqld starts. How can I set this variable permanent?

You may want to check the timezone in the php.ini file as well to make sure it's set correctly. Not sure of that's related to your issue or not.
