http://lnav.org is a powerful log file reader, designed to take multiple log files and order them by date. It understands log file formats using regular expresions and can highlight sections of line, find errors and warnings, and more.
This repository is for the log file format descriptions I've written so far.
You can install these by simply checking this directory out in your
~/.lnav/formats directory.
Some of these formats may use features that are only available in lnav
version 0.8.0 or above. If you get warnings, try renaming the
offending files to end in .json-unused to see if this fixes things.
