The #Log #File #Navigator, #lnav, is an advanced log file viewer for the #terminal. It provides an #easy-to-use interface for #monitoring and #analyzing your log files with little to no setup. Simply point lnav at your log files and it will automatically detect the Log Formats, index their contents, and display a combined view of all log messages. You can navigate through your logs using a variety of hotkeys. Commands give you additional control over lnav’s behavior for doing things like applying filters, tagging messages, and more. You can then analyze your log messages using the SQLite Interface.
