************************************************************************
************** WARNING: A dark dungeon lies ahead of you  **************
************************************************************************

Rally does not have control over the configuration of the benchmarked
Elasticsearch cluster.

Be aware that results may be misleading due to problems with the setup.
Rally is also not able to gather lots of metrics at all (like CPU usage
of the benchmarked cluster) or may even produce misleading metrics (like
the index size).
