How to Show Last Logins of all PRTG Users

PRTG can show the time when a user logged in the last time, but if you want to cleanup the user database, then this is the fast way to display inactive users.

Please copy and save the script that we provide below as <name>.ps1 and alter the parameters displayed in the head of the script:

-server "<address of PRTG server>" -username "<username of a PRTG Administrator user>" -passhash "<passhash of the PRTG Administrator user>"

Note: You can find the required passhash under Setup | Account Settings | My Account. Click Show Passhash to display it (see PRTG Manual: Account Settings—My Account).

After the execution of the script, you will receive a result like this:

test

The list will allow you to add filter criteria for each column and show all configured users.
