If you log in to the Observium machine and check the RRD folder you should probably be able to find the creation date for the device folder and its RRD files.
Thats the only way I can think of

Hi Everyone!

Is there a way to find out the date of the "first contact" with a device from Observium?
I mean for example the date when the first discovery was run on a specific device, or something like this?
(Currently the device's event log runs out after half a year.)

Any ideas?

Regards,
Tylla
