The Logfile Navigator, lnav for short, is a curses-based tool for viewing and analyzing log files. The value added by lnav over text viewers / editors is that it takes advantage of any semantic information that can be gleaned from the log file, such as timestamps and log levels. Using this extra semantic information, lnav can do things like: interleaving messages from different files; generate histograms of messages over time; and providing hotkeys for navigating through the file. It is hoped that these features will allow the user to quickly and efficiently zero-in on problems.
