This is just an example of how you can build an UI on top of the
existing Admin/Monitor interface. This page will only
work as it is if you enabled the API (which is disabled by default)
and you're using the default values. Edit the backend settings in
the admin.js JavaScript code to adapt it to your
configuration if you changed anything.
The Server Info tab, as the name suggests, provides
you with a view of the information related to the Janus instance
you're using, e.g., in terms of the features that have been enabled,
the modules that are available and so on. That's the same info you'd
get contacting the Janus API at the /janus/info backend.
The Settings tab instead allows you to inspect a
few of the current settings in Janus (e.g., debug level and so on)
and provides you with a way to change them dynamically.
The Plugins tab presents the list of media plugins
available in this Janus instance, and allows you to interact with
them, assuming they implement the handle_admin_message API.
The Handles tab allows you to browse the currently active sessions
and handles in Janus. Selecting a specific handle will provide you
with all the current info related to it, including plugin it is
attached to, any plugin specific information that may be relevant,
ICE/DTLS states, amount of data being exchanged and so on. This
section is especially helpful when you want to debug issues with
a PeerConnection: you can find more details in
this blog post.
Finally, the Stored Tokens tab allows you to list
existing authentication tokens, create new ones, associate plugin
permissions and the like. This feature will only be possible if
you enabled the stored-token authentication mechanism in Janus, of course.
