The logs page in the PRTG web interface does not load. What can I do?



Your Vote:



When I open Logs in the PRTG web interface via the main menu, the log table does not load. The page remains empty and does not display logs, while the mouse pointer indicates that it is loading.

Why am I not able to view the PRTG logs? How can I access the logs table?

Loading Logs in the PRTG Web Interface: Disable Your Ad Blocker

If you open Logs (<your-prtg-server>/log.htm) in the PRTG web interface via the main menu and the logs table does not show up, the reason is most likely that an ad blocker is enabled in your web browser. Ad blockers like uBlock Origin block log.htm so that PRTG cannot display the logs table or it can only display the table after reloading the page (F5).

Note: We strongly recommend that you disable your ad blocker in a browser that you use to access the PRTG web interface. Ad blockers might affect other functions of PRTG as well.

Whitelist Your PRTG Server

You can also whitelist your PRTG server in the ad blocker settings. If you use uBlock Origin, for example, open its dashboard, open the tab Whitelist, and enter the address that you use to access PRTG via your web browser. Alternatively, click the big on/off switch to disable uBlock Origin for the site. The PRTG logs table will now load again.
