-# GJSON:
-GJSON also parses JSON data, but uses paths to name and identify fields of your choosing.
-
-The GJSON parser supports 5 different configuration fields for json objects:
-
-1.'gjson_tag_paths'
-2.'gjson_string_paths'
-3.'gjson_int_paths'
-4.'gjson_float_paths'
-5.'gjson_bool_paths'
-
-Each field is a map type that will map a field_name to a field_path.  Path syntax is described below.
-Path maps should be configured as:
-`toml gjson_tag_paths = {"field_name" = "field.path", "field_name2" = "field.path2"}`
-
-Any paths specified in gjson_tag_paths will be converted to strings and stored as tags.
-Any paths otherwise specified will be their marked type and stored as fields.
-
-#### GJSON Configuration:
-Paths are a series of keys seperated by a dot, ie "obj.sub_obj".
-Paths should not lead to an JSON array, but a single object.  
-An error message will be thrown if a path describes an array.
-Further reading for path syntax can be found here: https://github.com/tidwall/gjson
-
-As an example, if you had the json:
-
-```json
-{
-  "name": {"first": "Tom", "last": "Anderson"},
-  "age":37,
-  "children": ["Sara","Alex","Jack"],
-  "fav.movie": "Deer Hunter",
-  "friends": [
-    {"first": "Dale", "last": "Murphy", "age": 44},
-    {"first": "Roger", "last": "Craig", "age": 68},
-    {"first": "Jane", "last": "Murphy", "age": 47}
-  ]
-}
-```
-with the config:
-
-```toml
-[[inputs.exec]]
-  ## Commands array
-  commands = ["/usr/bin/mycollector --foo=bar"]
-
-  ## Data format to consume.
-  ## Each data format has its own unique set of configuration options, read
-  ## more about them here:
-  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
-  data_format = "gjson"
-
-  name_override = "gjson_sample"
-
-  gjson_tag_paths = {"first_name_tag" = "name.first"}
-  gjson_string_paths = {"last_name" = "name.last"}
-  gjson_int_paths = {"age" = "age", "Janes_age" = "friends.2.age"}
-```
-
-would output the metric:
-`gjson_sample, first_name_tag=Tom last_name=Anderson,age=37,Janes_age=47`
