Intercept Tomcat log

Hi,

Is there any way to intercept log entries?

We are building a monitoring mechanism that open JIRA issues for some kinds
of uncaught exceptions, so I need to monitor exceptions that appear on
catalina.out log file.

I cannot say that I am entirely surprised.
But it is nevertheless rather funny, since I am sure that any kind of system nowadays 
already uses perl as part of some standard OS packages.
Even Windows does...

I agree. But then why did you start bottom-posting after the previous person top-posted ? 
That was confusing too.

confusing.

Nobody forces you to.

Yes, but some people prefer it this way.

Why not ?

I am going to answer this with a java.util.logging point of view.

You can install multiple handlers
(http://download.oracle.com/javase/6/docs/api/java/util/logging/Handler.html),
even dynamically.

You can attach this to the root logger "" or a specific level "com.ice-sa" etc.

Following a pattern like the MemoryHandler you can even report back logs upon a
triggering condition.

The offline processing of tomcat log files is the first option, but we were
looking for something that could allow us to do on-line processing, or
processing with short delay time.

Unhappily the corporation I work don't have pearl on the list of languages
with official production environment setup.

Thanks!

and have a look here :

http://cpan.uwinnipeg.ca/htdocs/JIRA-Client/JIRA/Client.html

and about parsing the logfiles, here :

http://cpan.uwinnipeg.ca/search?query=logfiles&mode=dist

perl/CPAN rocks !

 Implement custom log4j appender?

 I'd rather use offline tool (perl script?) to process logfiles.
