# Janus WebRTC Server: Admin/Monitor

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 `Transports` tab does the same for transport plugins, and allows you to send requests to tweak the behaviour of the plugin or query its internal state, assuming they support this somehow.

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.
