FW: Parsing Log4j log file
Hi,
I want to read the log4j log file in my program and want to search some information from the log file.
If there is any API available for log file parsing/reading, Please let me know.
regards,
Prashant

Hi Jacob,
Thanks for very valuable response!
Yes I need to store the information retrieved from the log file to the database.
That's why I couldn't use this tool directly.
Your 1st and 2nd approaches I think could be useful. Will explore it and let you know.
Thanks a lot.
regards,
Prashant

I would either use Chaisaw II [1] or look at the code it uses to read log
files. It can read XML formatted files as well as regular log files, as long
as you give it the pattern the log was written in. See the
LogFilePatternReciever [2]. Chainsaw can even read a remote file using the
VFSLogFilePatternReciever [3], so I would suggest using the tool rather than
writing the app yourself unless you have very unique requirements.

Hi Douglas,
Thanks for the response.
But the problem with that approach is that there are n number of log files already exist. And those are not in XMLLayout.
So This approach wouldn't be useful here.
Please let me know if any other efficient solution for this.
regards,
Prashant

one approach, use the XmlLayout, and then you can use your favorite XML
