Catalina Log Reader

Some web applications generate lots of exceptions and dump exaggerated amounts of stacktraces. i’ve wrote a small script in perl that parses catalina.out and can remove or shorten those stacktraces and also prove some syntax highlight.

Usage

Start clog with:

$ clog

Check the last 100 lines from the log:

$ clog 100

If you want only to see the first five lines of the stacktrace:

$ clog -st 5

If you want to see the full stacktrace:

$ clog -e 100

The code is available here.
