Debug level to be set for Tomcat bug reporting

[Kumar Sai-A18253 <sa...@motorola.com>]

Hi,
 
The default debug level is 0 for Tomcat.
When I looked at http://tomcat.apache.org/bugreport.html website for
Tomcat bug reporting, they mentioned that they need Log file excerpts
mentioned below
Log file excerpts - Review your logs files, reproduce the bug with
debugging enabled in your Apache Tomcat configuration. Then submit any
relevant sections of the log which help document the bug.
 
In our project we didn't change debug level for Tomcat...using default
debug level 0.
If we get any issues, we need to capture Log file Excerpts to open
Tomcat bug for your investigation.
My question is which debug level  ( 0 .. 4) we need to set in our
project to get sufficient logs for resolving Tomcat bug.
At the same time , we may not set high debug level  as it may degrade
server performance.
Please advice as soon as possible.
 
Thanks for your help.
 
Thanks,
Sai.
