erlang node monitor

Visualize registered processes in an erlang node. This program takes a snapshot of the registered processes and its links and visualizes them as a network of nodes.

UI Preview

Start now

  1. Build and Start: make run (from root folder)
  2. Once server is running, open file priv/ui/build/index.html with a browser.

Add to your application

  1. Call erlang_node_monitor_app:start() where you want to start monitoring your node. When the application starts, a WebSocket server will be initialised in ws://localhost:5000, which is going to be used to communicate with the client.
  2. Open file priv/ui/build/index.html with a browser. When the page is loaded a fresh snapshot is going to be visualized.
