server.log size is too big

[asookazian]

In less than a couple of hours today, with one Seam2.0.0.GA app on my JBoss 4.2.1.GA, the server.log exploded to 300MB+.

When I changed the overall threshold to WARN in log4j.xml, the size of the log was much smaller after a few minutes (approx. 5KB).

It seems after perusing the server.log that ajax4jsf and Seam are very verbose at the DEBUG level. I'm not sure how valuable that info is to a corporate developer.

Anybody else encountering this problem and what is the recommended solution (obviously adding filters like below but you need to know what all the culprits are @ DEBUG level to filter out from server.log).

In prod, is the recommendation to set the threshold for server.log to ERROR?

\jboss-4.2.1.GA\server\default\conf\jboss-log4j.xml:

<!-- ================ -->
 <!-- Limit categories -->
 <!-- ================ -->

 <!-- 01/11/08 - Limit the org.jboss.seam to INFO as its DEBUG is verbose -->
 <category name="org.jboss.seam">
 <priority value="WARN"/>
 </category>

thx.

WARN is usually good for production. DEBUG is a very fine log level and is usually appropriate for development or problem solving.

You can set in the file appender also.

I'd go with INFO over WARN and use














As if you are a production support customer, we almost always ask for your server.log, and it may save you some time if you can upload a log straight to us without changing the Threshold back to INFO and reproducing the problem, and a filesize of 2MB is good, it is not easy to wade through a 200MB log file.

code tags would help :)
