 # Feature
 - All the heartbeats (no matter **monitor** or **tail (logs)**) are automatic destroyed.
-- The `PM2` processes are watched by a FSWatcher ([chokidar](https://www.npmjs.org/package/chokidar)), but not manually polling.
-- Communicated with `PM2` through **RPC** socket directly, but not `PM2` programmatic API and no more **sub/sub-emitter** bullshit (consumes memory and CPU usage).
+- The `PM2` processes are watched by a subscribed emitter.
+- Communicated with `PM2` through **RPC** socket directly.
 - Socket.io between client and server.
 - Monitor CPU and Memory usage of server in a real-time.
 - Monitor `PM2` processes in a real-time.
-- Supports: process memory monitor, PM2 restart/stop.
+- PM2 restart/stop/delete.
 - Supports [ANSI color codes](#tail_logs) by [ansi-html](https://github.com/Tjatse/ansi-html).
