# Script to name all ec2 instances after the node name allocated to the
# elasticsearch running on that instance. This makes it easy to track back
# to the physical system from visualization tools like bigdesk and head.
#
# Run directly on any elasticsearch node or port forward 9200 to a node in the
# cluster. Simple run without arguments:
# ./ec2names.py
