listing all applications in manager across configured virtual hosts
Hi all:
We have configured a Tomcat with two virtual hosts, one for hosting client-facing applications on a "vanity" name, and the other for the "machine" which hosts private URLs for access to admin/diagnostic functions by admins only.
We have an instance of Tomcat manager on the running just fine on the "machine" host.
Requests to "/manager/html/list" only shows applications running on the "machine" host, and not those running on the "vanity" host.
I understand from [0] that "If you have Tomcat configured to support multiple virtual hosts (websites) you would need to configure a Manager for each."
But if I request the complete server status from that same manager running on the "machine" host, the "Application list" heading in the output contains a listing of all deployed applications ordered by all configured virtual hosts.
Clearly the manager has knowledge of all configured applications regardless of virtual host.
Is is possible to configure a manager to just list all applications from all virtual hosts on the main "List Applications" screen?
My environment is Tomcat 9.0.29 with OpenJDK 1.8.0_232 on Debian Linux.
Thanks,
Jason

The general idea seems like a reasonable use case.
Yes, I will look into it and see what I can come up with in terms of a
patch we can try.

Clearly, it's possible because you can see it on another screen within
the manager. If all you want is a list (and not full management), then
it should be fairly easy to accomplish.
The Manager application isn't very complicated. Would you care to
develop a patch/PR for this? I'd recommend making it somehow optional,
as users with separate Managers for many many virtual hosts probably
don't want all that exposed.
