Configuring HornetQ standalone server logging

[zman12345]

This msg is just FYI with examples you can use!

First of all read the brief info here: http://hornetq.sourceforge.net/docs/hornetq-2.0.0.BETA5/user-manual/en/html/logging.html

I used to work with log4j and it took me some times to get JUL (java.util.logging) working. HornetQ logging configured. By default HornetQ is using JUL, and it's level are different from Log4j. So if you want to see more server details for example, you would need to add a file to HORNETQ_HOME/config/logging.properties like this:

handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=ALL
java.util.logging.ConsoleHandler.formatter=org.hornetq.integration.logging.HornetQLoggerFormatter
.level=SEVERE
org.hornetq.level=CONFIG
org.hornetq.core.management.level=FINE

* Note you need ".level" for each category!

And the levels are (don't use Log4j level name!!!)

SEVERE (highest value)
WARNING
INFO
CONFIG
FINE
FINER
FINEST (lowest value)

Restart your HornetQ server now and you should nee more messages.


But if you want to use log4j instead, the HornetQ document didn't mention that you have to set one more line in order to see anything below INFO. This is how, in your HORNETQ_HOME/config/logging.properties file, type this:

handlers=org.hornetq.integration.logging.Log4jLoggerHandler
.level=ALL

Then you need to edit HORNETQ_HOME/bin/run.bat(sh) to include log4j config file. Like this on run.bat after the set JVM_ARGS line:

set SCRIPT_DIR=%~dp0
set JVM_ARGS=%JVM_ARGS% -Dlog4j.configuration=file:///%SCRIPT_DIR%%CONFIG_DIR%\log4j.properties

Then you can add log4j.properties file into HORNETQ_HOME/config/stand-alone/non-clustered dir:

log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=%05p | - %m%n
log4j.rootCategory=WARN, STDOUT
log4j.category.org.hornetq=INFO
log4j.category.org.hornetq.core.management=DEBUG

The Log4j Levels are:

FATAL (highest value)
ERROR
WARN
INFO
DEBUG
TRACE (lowest value)

I hope these are helpful to you.

Actually we overhauled how logging works in TRUNK some time back.

It's a lot simpler, there's a JIRA for this against the 2.0 release

[zman12345]

Yeah, I noticed the trunk no longer has the class: Log4jLoggerHandler!

So what is the JIRA link you have mentioned?

[timfox]

Have a look at the JIRA tasks against the 2.0 release, it's one of them.

There was also a forum discussion about this some time back.

Hi Tim,

I just read the latest CR1 doc on logging, and I think there is a typo in the example:

http://hornetq.sourceforge.net/docs/hornetq-2.0.0.CR1/user-manual/en/html_single/index.html#logging

org.hornetq.core.logging.setDelegateFactory(new Log4jLogDelegateFactory())

Should it be?

org.hornetq.core.logging.Logger.setDelegateFactory(new Log4jLogDelegateFactory())

[timfox]

Yes, you're right.

This is now fixed in trunk.

Thanks for the heads up! :)
