Package lnav: Information

The log file navigator, lnav, is an enhanced log file viewer that
takes advantage of any semantic information that can be gleaned
from the files being viewed, 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.
