Small command-line JSON Log viewer

fblog

A small tool to view json log files.

Filter

To filter log messages it is possible to use lua

fblog -f 'level ~= "info"' # will print all message where the level is not info
fblog -f 'process == "play"' # will print all message where the process is play
fblog -f 'string.find(fu, "bow.*") ~= nil' # will print all messages where fu starts with bow
fblog -f 'process == "play"' # will print all message where the process is play
fblog -f 'process == "rust" and fu == "bower"'
fblog --no-implicit-filter-return-statement -f 'if 3 > 2 then return true else return false end'

Customize

fblog tries to detect the message, severity and timestamp of a log entry. This behavior can be customized. See --help for more information.
