To get information for a given schema:

Method : GET

URI : /stream/<schema_name>/info

Example

curl -X GET http://192.168.1.105:18080/stream/ecomm/info

Response

{
   "num_streams":1,
   "streams":[
      {
         "name":"visitor",
         "num_events":1,
         "state":1,
         "type":1
      }
   ]
}

As you note, it returns list of schemas and their streams, apart from some more important info around notifications.
