                    "index_total": 4,
                    "index_time_in_millis": 5,
                    "index_current": 0,
                    "delete_total": 0,
                    "delete_time_in_millis": 0,
                    "delete_current": 0
                }
            }

Try this:

var your_variable = Object.keys(x.indices)[0];

This will return the first key in array of keys like "get56_name"

Object.keys(x["indices"])[0]

Hope this is what you are asking
