Hi Stephano,

If you delete a sensor / device in PRTG the historic data of the device will be purged as well. The only way to retrieve the data is to restore the historic data from a backup. You'll also need to copy an older version of the PRTG Configuration.dat to the default directory

C:\ProgramData\Paessler\PRTG Network Monitor

to restore the configuration of the object. Please bear in mind that all configuration changes done in the mean time will be lost.

Best regards
