Host Durations off after moving VM to another ESX Host

[krobertson71]

We moved our test Nagios XI instance to another ESX Host (Dedicated). After the move and startup I have noticed that the old hosts are displaying negative durations and have last check times set in the future - 5-22-2015

The ESX host had to be rebooted after the move due to a network issue and something else (waiting to hear back on that).

The host I added after the move is fine.

Monitoring seems to be performing just fine, but these hosts that were present before the move start at -60 and count down to 0 then start again and have a last check date 5-22-2015.

The ipaddress of the Nagios XI server did not change, nor then name so no DNS issues.


Stumped on this one.

Make sure your system and php time is synced. You can review our documentation on changing the system time here:

You may need to reboot the server as well.

Note: If this doesn't help, you can try removing the "retention.dat". This will set all of your checks as "pending".

Code: Select all

service nagios stop
rm -f /usr/local/nagios/var/retention.dat
service nagios start

Deleting the retention.dat file corrected the issue.
