kurento-monitor is a simple application that retrieves a few information about the media elements running in the Kurento Media Server in a given moment, such as pipelines, player endpoints, rtp endpoints, etc.

The retrieved data is printed to the standard output in a JSON format

Installing

npm install

Setup and Running

Create a config/default.json file , or copy the example config

cd config
cp default.example.json default.json

then start it

node server <Websocket-URI>

Where Websocket-URI is the ws/wss URI of the kurento media server.

Example of running

node server wss://127.0.0.1:8443/kurento

I called this app kurento-monitor because i used it when i had to monitor the status of the Kurento Media Server while running a few other applications. This app was handy to check if those apps were using too much resources and correctly opening/closing media elements.
