Outqueue ‘Expert mode’ - Admin
The administrator of a hub has the option of displaying which items are currently in the queue. This can be done in “Admin” under ‘Inspect queue’. Selecting this menu item takes you to <URL_OF_THE_HUB>/admin/queue.
In this view, the entries are displayed in a table:
| Total Entries | Destination URL | Priority |
|---|
It is not possible to edit the entries.
However, there is also an ‘expert mode’ for this view, which unfortunately cannot be accessed via the administration menu. It must be appended to the URL ‘?expert=1’, so the call is <URL_OF_THE_HUB>/admin/queue?expert=1.
Now, in addition to the three pieces of information previously displayed, three buttons are shown in the table:
- Mark hub as permanently offline
- Empty queue for this hub
- empty Button - Retry delivery to this hub
These three buttons can be used to perform the actions mentioned above.
To avoid having to append the string to the URL every time, you can, for example, create an app with this URL and add it to the app menu or pin it to the navigation bar.

Thanks for discovering this hidden feature go to Harald Eilertsen, who stumbled upon it while working on the source code.
