ESI: Elastic Search Investigation

Why?

Sick of messing with curl and reading through the output to figure out what's what with elastic search.

Usage

Usage: esi.py [options]

Options:
  -h, --help            show this help message and exit
  -H HOST, --host=HOST  Host running elasticsearch
  -p PORT, --port=PORT  Port running elasticsearch
  --nodes               Get summary of nodes JSON
  --shard-distribution  Get shard distribution JSON
  --replica-distribution
                        Get replica distribution JSON
  --cluster-state       Get cluster state JSON
  --cluster-health      Get cluster health JSON
  --node-stats          Get node stats JSON
  --shards              Get shards JSON
  --indices             Get indices JSON
  --aliases             Get aliases JSON
  -v, --verbose         Enable verbose output

Examples

Which node is which?!

Nodes have IDs (eg, Su4FER3NTNqwB0W5ywjDRw), but they write log messages using odd names (eg, [Whitman, Debra]). What they do not have is hostnames and PIDs!

In the meantime, this makes it a bit easier to get a quick summary of nodes:

$ ./esi.py --nodes
{u'Su4FER3NTNqwB0W5ywjDRw': {u'attributes': {},
                             u'name': u'Whitman, Debra',
                             u'transport_address': u'inet[/10.110.246.163:9300]'},
 u'bvmvdyVLRHK4mYQThHP7iQ': {u'attributes': {},
                             u'name': u'Steel Serpent',
                             u'transport_address': u'inet[/10.32.255.68:9300]'}}

Until I add some more features you can do the rest, mapping whatever you're looking at to what you know of your server addresses.
