+# 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:

+  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`
