turning off per class logging
Hello
I wish to suppress zookeeper logging at the class level. I see a lot of
messages in my log along these lines:
2015-02-23 16:54:53,192 - INFO [NIOServerCxn.Factory:/0.0.0.0:2181
:NIOServerCnxnFactory@197] - Accepted socket connection from /

client)
I want to set logging for the NIOServerCnxn and NIOServerCnxnFactory
classes to WARN, but keep everything else at the INFO level. How can I do
this?
I tried to set log4j properties at the class level:
java -Dlog4j.logger.org.apache.zookeeper.server.NIOServerxnFactory=WARN
-Dlog4j.logger.org.apache.zookeeper.server.NIOServerCnxn=WARN
-Dzookeeper.log.dir=/var/log/ -Dzookeeper.root.logger=CONSOLE -cp
/etc/zookeeper::/usr/lib64/zookeeper/bin/../zookeeper-3.4.6.jar:/usr/lib64/zookeeper/bin/../lib/jline-0.9.94.jar:/usr/lib64/zookeeper/bin/../lib/log4j-1.2.16.jar:/usr/lib64/zookeeper/bin/../lib/netty-3.7.0.Final.jar:/usr/lib64/zookeeper/bin/../lib/slf4j-api-1.6.1.jar:/usr/lib64/zookeeper/bin/../lib/slf4j-log4j12-1.6.1.jar
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.local.only=false
org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/zoo.cfg
This didn't work: log messages for those two classes are still coming out.
I tried with the lower case ("warn" instead of "WARN") and that didn't work
either
Further playing around with setting zookeeper.root.logger to ERROR makes me
wonder if zookeeper is honoring these command line parameters at all
I don't see any reference to a log4j.properties, and running it under
strace tells me its not opening a log4j file anywhere.
any ideas?

Thank you, that was what was wrong.
I thought log4j could be set at the command line because I saw these lines
in zkServer.sh:
"-Dzookeeper.log.dir=${ZOO_LOG_DIR}"
"-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}"
Are these not related to log4j?
Thank you for your help

Hello,
This is some general feedback, nothing specific to zookeeper.
Where in the log4j documentation does it say you can set the log level per
class as a jvm property? I've not seen this before and couldn't see it
when I looked through the documentation.
http://logging.apache.org/log4j/2.x/manual/configuration.html#SystemProperties
.
I'd suggest using a log4j xml configuration file as documented here
