Open Source TypeScript Log Analysis Software

Inputs watch log files for changes, send new log messages to the server, which broadcasts to web clients. Log messages are tagged with stream and source information based on user configuration. log.io has no persistence layer. File inputs are informed of file changes via inotify, and log messages hop from input to server to web client via TCP and socket.io, respectively. 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. Input paths can be a file path, directory path or a glob. Additionally, watcher options can be provided for more fine-grained control over file watching mechanics and performance. The file input connects to the server via TCP, and writes properly formatted strings to the socket.
