Thanks very much for your interest in Rally.

This appears to be a user question, and we'd like to direct these kinds of things to the Elasticsearch/Rally forum. If you can stop by there, we'd appreciate it. This allows us to use GitHub for verified bug reports, feature requests, and pull requests.

There's an active community in the forum that should be able to help get an answer to your question. As such, I hope you don't mind that I close this.
