How to use FastFile
I am using log4j beta5 and want to try async file appender FastFile.
However I could not get it to work.
I have built the disruptor jar using project from
https://github.com/LMAX-Exchange/disruptor so my disruptor is 3.0.1 not
3.0.0, dont know if it matters.
I simply follow the sample setup from
http://logging.apache.org/log4j/2.x/manual/async.html#Performance.
But I could not see anything log into my log file, I can see the log file
created but nothing inside.
If I simply change from FastFile to File, I can see all the logs that
suppose to appear.
I have the following jars in my project
log4j-api-2.0-beta5.jar
log4j-core-2.0-beta5.jar
log4j-jcl-2.0-beta5.jar
log4j-slf4j-impl-2.0-beta5.jar
In my project I mainly use slf4j but even if I try to use log4j api direct,
it still doesnt work.
here is my log4j2.xml
<configuration status="DEBUG">
<appenders>
<FastFile name="FastFile"
fileName="D:/Projects/TestingProject/logs/log4jtest.log"
immediateFlush="false" append="false" suppressExceptions="false">
<PatternLayout>
<pattern>%d %p %c{1.} [%t] %m %ex%n</pattern>
</PatternLayout>
</FastFile>
</appenders>
<loggers>
<root level="debug" includeLocation="true">
<appender-ref ref="FastFile"/>
</root>
</loggers>
</configuration>
What am I doing wrong? or do I need to check for any dependency for
disruptor?
Thanks

Re: How to use FastFile
Posted by Remko Popma <re...@yahoo.com>.
Steven,
The buffer size used in FastAppenders is 256 Kb.
Glad that with asyncRoot you are seeing logs.
With asyncRoot, log events are first stored in a ringbuffer, then a separate thread takes them out and logs them to a file.
Based on the log snippet you attached, it looks like we need to check if and how tomcat signals a shutdown and if we can pick up that signal to shutdown the threadpool.
Thanks for bringing it to our attention!
I have filed Jira ticket LOG4J2-222 for this. I will take a look and see what I can do. This may take some time.
Best regards,
Remko

Subject: Re: How to use FastFile
Thanks, I tried using asyncRoot and everything seems to log fine and I do see a lot of logs.
And logs do seem to be flushed immediately so I do not know if the hook on shutdown is been called correctly or not.
I am using struts and spring so I see a lot of logs (log level at DEBUG) just by starting up tomcat, so I am wondering when I use <root> how come I dont see any log at all? how much log do I have to write before it starts to flush out?
and one thing I found is that when I use asyncRoot and when I shutdown tomcat I see the following message regarding to clearing references and thread local.
The last one is related to log4j.

Re: How to use FastFile

Steven,
In your config, instead of <root>, try <asyncRoot>. You need the disruptor jar on the classpath. This will result in events being flushed to disk immediately, but in an efficient way: in batches, not one by one.
I need to take a look at the behavior on Tomcat shutdown. There is a shutdown hook that should flush remaining events, but perhaps you found a bug.
Can you try <asyncRoot> and let me know if that resolves the issue?

Thanks Remko for the comment
Ok I now understand why I dont see the log.
I am running in a tomcat, but when I shutdown my web server I dont see log
being flushed out to file.
Does that mean even when I run my application for a while and even after
some logs are flushed out then I shutdown my server there will be some log
entries left in memory and lost?

Two more things:
disruptor 3.0.1 is fine.
Your layout pattern doesn't actually use location, so if you use Async (Logger or Appender) I'd recommend you set includeLocation=false for better performance.

Hi,
FastFile appenders are buffered.
You won't see output in the log file until you log a lot.
To see output immediately you should either specify immediateFlush=true or use Async Loggers or AsynchAppender (they will auto-flush efficiently).
Hope this helps,
