I rarely look into my ElasticSearch server logs, but when trying to debug a current issue (JVM crashes), I noticed that I have not been looking in a while. The wrapper is properly logging. In fact, those logs complain about log4j not being setup: INFO | jvm 1 | 2012/08/17 11:33:09 | log4j:WARN No appenders could be found for logger (node). INFO | jvm 1 | 2012/08/17 11:33:09 | log4j:WARN Please initialize the log4j system properly. INFO | jvm 1 | 2012/08/17 11:33:09 | log4j:WARN See [http://logging.apache.org/log4j/1.2/faq.html#noconfig](http://logging.apache.org/log4j/1.2/faq.html#noconfig) for Is logging.xml the file used for logging? I never had an issue before. I am using the service wrapper, so I added the xml file to my classpath. Here are some settings from my elasticsearch.conf file: wrapper.java.classpath.4=/shared/elasticsearch-config/config/logging.xml wrapper.java.additional.13=-Des.path.conf=/shared/elasticsearch-config/config/ The java process starts up with the correct classpath, but log4j still complains. Not sure at what point I lost logging. Cheers, Ivan -- ---

Ivan, I'm running elasticsearch-0.19.8 and It's using "config/logging.yml" not .xml. There is no reference to it all in elasticsearch.conf.

Yup, that was it. Fat-fingered typing on my part. No wonder logging stopped at some point. So many years of typing .xml that I did not even spot the error.
