* Elasticsearch
+** Introduction
+
+GeneNetwork uses elasticsearch (ES) for all things considered
+'state'. One example is user collections, another is user management.
+
+** Example

To get the right environment, first you can get a python REPL with something like
: env GN2_PROFILE=~/opt/gn-latest ./bin/genenetwork2 ../etc/default_settings.py -cli python

+** Health
+
+ES provides support for checking its health:
+
+: curl -XGET http://localhost:9200/_cluster/health?pretty=true
+
+#+BEGIN_SRC json
+
+
+ {
+ "cluster_name" : "asgard",

+ "relocating_shards" : 0,
+ "initializing_shards" : 0,
+ "unassigned_shards" : 5
+ }
+
+#+END_SRC
+
+Yellow means just one instance is running (no worries).

+To get full cluster info
