LogTail is a modern Cocoa application for Mac OS X to view and monitor log files that reside locally on your
system and on remote systems that allow SSH connections.
It reads log files and outputs their contents as they change, and can follow or "tail" the file in a way similar to the Unix 'tail' utility.
LogTail is helpful in monitoring application and system log files which are updated constantly at runtime.
It allows you to set up filter and highlight rules that can be used to show/hide or colorize lines with matching words or patterns.
This allows you to focus the important data in your log files.
