I use logback-access instead of tomcat default valve.
I used %b pattern, but output is so weird.
First, i use class "ch.qos.logback.access.tomcat.LogbackValve"
I wrote this pattern.
[%t]\t%U\t%s\t%D\t%b
Second, i use class "org.apache.catalina.valves.AccessLogValve"
I wrote this pattern.
pattern="%t	%U	%s	%D	%b
I think they are same, and try use same time. But "%b" attribute output is different.
This is example.
First, Logback.
[02/Jun/2015:20:12:28 +0900] /test/testLayout.css 200 366 -
Second, Tomcat valve.
[02/Jun/2015:20:12:28 +0900] /test/testLayout.css 200 367 2769
Logback's output is "-" but Tomcat is "2769"
I think Tomcat valve's value is correct.
Why they are different?
Please tell your advice.
ps. Logback version is 1.1.3. I use logback-core-1.1.3.jar, logback-classic-1.1.3.jar. When use logback-access-1.1.3 at the same time, tomcat puts error.
