Simple python script to process stdin from include settings API to dump number of primary shards and replica counts.

dump_index_shards_and_replica_counts.py

#!/usr/bin/env python

# Use via: curl -X GET http://localhost:9200/_all/_settings?pretty

import sys, json

#json_doc = json.load(open(sys.argv[1]))
json_doc = json.load(sys.stdin)
#json.dump(json_doc, sys.stdout, indent=4, sort_keys=True)

for idx,v in json_doc.iteritems():
    settings = v['settings']['index']
    print("%s: primaries: %s, replicas: %s, unassigned: %s" % (idx, settings['number_of_replicas'], settings['number_of_shards'], settings['unassigned_shards']))

Example output:
