how does the tomcat log generated? log4j?
Hi:
I wonder how is the tomcat log generated,I mean the log like this;
localhost_access_log.2010-12-20.txt
I want to export the logs to db. Some one suggestion I directly add
one Appender <http://logging.apache.org/log4j/1.2/apidocs/index.html>
if tomcat also uses log4j to generate the logs and I have access to
the tomcat's log4j config file.
More details can be found in this post:
http://stackoverflow.com/questions/4486620/randomaccessfile-probelm
So I wonder if this is possible?

Of course not. Just a web nickname. Since I like
maven<http://maven.apache.org/>,it
is the best build tool I have ever used.

You can use JDBCAccessLogValve

AccessLogValve (and ExtendedAccessLogValve) manage the log file by
themselves. They do not use logging framework in this sense.

Thanks for your kind. I prefer to this manner also. And it is why I ask
problems in the stackover. :)

Oh well, if the boss says so.
But then I would /still/ recommend writing something in java which reads the above
logfiles and feeds the database. Seems a bit more reliable and more scaleable to me.
What if the database is not available at some point for whatever reason ? You stop tomcat,
or you lose the information ?
In any case, you should look at the current access log files, and count the number of
lines which it writes per second|minute|hour, and ask yourself if you want this number of
transactions going into your database system in real-time.

Thank you anyway,although having Tomcat writing logs directly to a database

Re: how does the tomcat log generated? log4j?
Posted by André Warnier <aw...@ice-sa.com>.
The logging page which I pointed you to, does not say that Tomcat uses log4j.
It says that you /can/ configure Tomcat to use log4j, instead of the default "juli"
logging. It even provides instructions to do so.
The AccessLogValve documentation page does not say either that it uses log4j.
But what it does say at the very beginning, is that the output file is changed every day
at midnight. So if you only read the files up to last night at midnight, you will never
encounter the problem that something is still writing to it.
Also, I do not know what your ultimate purpose is, but there exist already several
open-source programs which read a logfile in the format produced by the Tomcat
AccessLogValve, parse it, and produce nice graphical statistics out of it (like webalizer
or awstats). Maybe you are re-inventing something which already exists ?
Web access statistics are not usually something which needs to be accurate in real-time.
Having Tomcat writing them directly to a database may have a noticeable impact on your
applications performance. That's why this is something usually done off-line.

Re: how does the tomcat log generated? log4j?
Posted by maven apache <ap...@gmail.com>.
Perhaps I’m not making myself clear,in fact I want to do some processing
work to the the logs created by the access log
valve<http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access_Log_Valve>to
database.
For example:the log:
10.33.2.45 - - [08/Dec/2010:08:44:43 +0800] "GET /poi.txt HTTP/1.1"
200 672 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US;
rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8"
will be saved in the db in this format:
ip time method
uri status bytes browser platform
------------------------------------------------------------------------------------------------------------------------------------------------------------
10.33.2.45 2010-10-08 08:44:43 GET /poi.txt 200 672
Firefox/3.6.8 winxp
And now I meet some problems when I read the log file like:
localhost_access_log.2010-12-20.txt
I read the file line by line,but sometime I can not get a complete line
since this file may be written in.
So,someone suggest me add a db appender(log4j),which will do the procesing
work and then export the log to db.
-------
Now,from the link you give me ,it seems that tomcat does use log4j to create
its access log.

Hi.
It is not very clear what you are asking, specially since you do not specify which version
of Tomcat your are using, under which Java version and on which platform.
Assuming you are using Tomcat 6.0.x, the on-line documentation for logging is here :
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
Maybe read it first, and then come back if you have a specific question ?
(But then try to specify the question clearly)
