Elasticsearch AsyncAppender configuration

We've set up elasticsearch logging as described here logging elasticsearch
events with logstash
http://www.elasticsearch.org/blog/logging-elasticsearch-events-with-logstash-and-elasticsearch/ and
we want to use an AsyncAppender instead of using a SocketAppender directly
in order to avoid freeze times while logging but only xml log4j conf file
format supports AsyncAppender.

Is there another way to achieve this since elasticsearch doesn't use xml
conf files?

It's easy, just remove log4j jar and config/logging.yml, then add
log4j2.xml, log4j-api, log4j-core, log4j-slf4j-impl and slf4j-api jars to
the lib folder. Then you can set up async appenders with log4j2, which are
18x more performant than log4j 1.x appenders.

I can't see how removing the log4 jar and logging.yml will allow
elasticsearch to init log4j2 using the xml conf file since the allowed
suffixes are 'yml, yaml, json , properties' (
https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/common/logging/log4j/LogConfigurator.java#L48)
?

If you remove the log4j jar, the ES logging is initialized by a logging
facade called SLF4J, and this passes initialization to the underlying
logging framework, e.g. log4j2

Hello ! Sorry about reviving this topic, but i'm trying to use asyncappender too and so i followed the remarks here.
I seem to have log4j2 working, but can't use
${path.logs}/${cluster.name}_${node.name}

I'm not sure how to get those variables, any hint ?
