Logtool

Logtool is a handy command line program that can rapidly convert ASCII log files to a user-friendly format. It's capable of parsing syslog and multilog files, including various variants such as syslog-ng, with ease. With this program, you can choose from a range of output formats that suit your needs perfectly, including ANSI that's colorized for easy "at a glance" viewing; ASCII for reports that are emailed or viewed in terminals that don't support colors; CSV for quick import to your favourite database or spreadsheet; HTML for effortless web page generation; and RAW for absolutely no particular reason at all.

Not only this, but Logtool also allows for various configuration options to manipulate the parsed data to your desired output format. The time display format of a log entry can be modified as per your preference, and this tool offers the ability to strip down elements like the host or program fields based on your specifications. In a nutshell, Logtool is a highly useful software for anyone that frequently deals with log files and requires an efficient solution for converting these logs into a more usable format.
