Nagios Core - retrieve date server was added to Nagios?

[rewt75]

Hi. We're running Nagios Core 3.x with a Groundwork front end on it. We've been asked to provide a list of all servers that were built in 2014 and I wanted to see if there's any way to extract this information from Nagios. Is the date on which a server was added into Nagios stored anywhere? If so, how can I query by this and get a list of servers added after a certain date?

Thanks!

If not changed afterwards, the date of the config files might tell you something.

Yes, that would be how I'd check, or looking at the current list of hosts, then checking archived log files for the first time their names came through. Additionally, we do not support Groundwork, they have their own support channels which should be able to assist.
