Subject RE: Tomcat 5.5 logging!
Date Tue, 23 Sep 2008 15:07:42 GMT
Actually when I press the TAB key I see that its really inserting a TAB key and not spaces
even after I restart tomcat the TAB key is still there and not spaces but if I open the log
file in vi I see that it enterperate it as spaces and my log analysis machine also see that
as spaces.
I have tries to use the \t '\t' and all of its variation but without any success.
Any other recommendation will be very appreciated.

Really a wild guess, because I don't know how Tomcat handles this 
"pattern" attribute :
Could it be that you are confused by the text editor that you use to 
write this configuration file ?  I mean when you insert a tab with the 
TAB key, the editor just inserts an appropriate number of spaces ?
And then maybe Tomcat, when it interprets the pattern, strips duplicate 
consecutive spaces ?

As another wild guess, have you tried to insert '\t' in your pattern, 
instead of pressing the TAB key.  (\t is the traditional way of 
representing a TAB in various circumstances).
Like :
 > pattern='%B\t%a\t%m\t%U\t%q\t%s\t%t\t%D    ...etc..

I make no guarantees about crashing your server.
