I built this standalone Java application that is connecting to elasticSearch using Transport client on my local machine. I am trying to figure out how to enable logging in it (This is to help me debug a wiered streamcorrupexception that i am getting in my production cluster) but not able to get it working. Can some one help This is how my log4j.xml looks like [log4j.xml](https://gist.github.com/1023a89b8f40f6e43fe9.git) and this is how my pom.xml file for application looks like [pom.xml](https://gist.github.com/ac1a373e8c043181f474.git). My java client does create simple TransportClient and executes match all query on it, the query is working ok. But i dont see much logs being created. I also tried setting --Des.logger.level and passing the -Dlog4j.configuration= _file:////Users/sunil/temp/log4j.xml_ [2015-Mar-13 06:56:41:437] DEBUG [Robert Bruce Banner] node\_sampler\_interval[5s] [2015-Mar-13 06:56:41:437] DEBUG [Robert Bruce Banner] node\_sampler\_interval[5s] [2015-Mar-13 06:56:41:500] DEBUG [Robert Bruce Banner] adding address [[#transport#-1][sunil.local][inet[localhost/127.0.0.1:9300]]] [2015-Mar-13 06:56:41:500] DEBUG [Robert Bruce Banner] adding address [[#transport#-1][sunil.local][inet[localhost/127.0.0.1:9300]]] but no luck so far -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

So i found out one way of enabling logs by hardcoding following in my application import org.elasticsearch.common.logging.ESLoggerFactory; ESLoggerFactory.getRootLogger().setLevel("TRACE"); Now i am able to see some log being generated.
