There are some web socket feeds available, generally these are used internally for config edit, status page, and logging, etc. However, we may add additional specific URLs for script use in due course. The general principle is that the websocket feed provides a stream of JSON objects in real time.

The status page uses /status/ but an additional port usage page /status/stats provides per second byte counts for all ports.

Note that you can define a js-url to be loaded at the end of pages to make use of these within the web user interface. This only works when logged in and from a trusted IP address, and not on pages where passwords can be entered.
