How to get a list of all indexes in python-elasticsearch

Question

How would I get a list of the names of an index in Python? Here is what I have so far:

>>> es=e.es
>>> es


        

Answer 1

how to get a list of all indexes in this cluster?

Use the wildcard. Works with elasticsearch-py.

for index in es.indices.get('*'):
  print index

Answer 2

I use curl to call the stats API and get information about the indices. Then I parse the JSON object that is returned to find the index names.

curl localhost:9200/_stats

In Python you can call curl using the requests library. I don't know of a way to do this using the Elasticsearch or Elasticsearch-DSL Python library.

Answer 3

You can get _mapping to get list of all indexes by doing something like that.

requests.get(full_elastic_url + "/_mapping")

Answer 4

If you are willing to use pyelasticsearch module they have support for the GET _mapping command, which produces the schema of the cluster. This will allow you to see the indices, and drill into each index to see doc_types, and their fields, etc. Here's an example:

import pyelasticsearch as pyes
es = pyes.ElasticSearch(["http://hostname0:9200", "http://hostname1:9200"]) ## don't accidentally type Elasticsearch, the class from the other two modules
schema = es.get_mapping() ## python dict with the map of the cluster

To get just the list of indices,

indices_full_list = schema.keys()
just_indices = [index for index in indices_full_list if not index.startswith(".")] ## remove the objects created by marvel, e.g. ".marvel-date"

Answer 5

Here is one way to do it with the get_alias() method:

>>> indices=es.indices.get_alias().keys()
>>> sorted(indices)
[u'avails', u'hey', u'kibana-int']

Answer 6

You can use the Cat API:es.cat.indices(h='index', s='index').split()
