Log.io Monitor Server Logs

Log.io : monitoring server logs in your browser Powered by node.js + socket.io  Harvesters watch log files for changes, send new log messages to the server via TCP, which broadcasts to web clients via socket.io.

Log.io uses a stateless TCP API to receive log messages, Writing a third party harvester is easy. Open a TCP connection to the server and begin writing properly formatted messages to the socket.

1. Install via npmnpm install -g log.io –user “ubuntu”
