Log.io

Log.io is a real-time log monitoring system written in JavaScript. It allows users to browse and search a stream of log messages in real-time within a web browser window. Log.io consists of three components: (1) third-party harvester(s) which collect log messages from log files via inotify events, (2) node.js server which receives log messages from harvesters via TCP, and (3) a web client which displays a stream of log messages broadcast by node.js server via socket.io. Log messages can be tagged with stream/node names and log-levels, which can be used by the web client for filtering. Log.io does not come with any persistent storage, and thus do not keep collected log messages.
