parsing JSON file using telegraf input plugin : unexpected Output - influxdb

Question

I’m new to telegraf and influxdb, and currently looking forward to exploring telegraf, but unfortunetly, I have some difficulty getting started, I will try to explain my problem below:
Objectif: parsing JSON file using telegraf input plugin.
Input : https://wetransfer.com/downloads/0abf7c609d000a7c9300dc20ee0f565120200624164841/ab22bf ( JSON file used )
The input json file is a repetition of the same structure that starts from params and ends at it.
you find below the main part of the input file :
{
"events":[
{
"params":[
{
"name":"element_type",
"value":"Home_Menu"
},
{
"name":"element_id",
"value":""
},
{
"name":"uuid",
"value":"981CD435-E6BC-01E6-4FDC-B57B5CFA9824"
},
{
"name":"section_label",
"value":"HOME"
},
{
"name":"element_label",
"value":""
}
],
"libVersion":"4.2.5",
"context":{
"locale":"ro-RO",
"country":"RO",
"application_name":"spresso",
"application_version":"2.1.8",
"model":"iPhone11,8",
"os_version":"13.5",
"platform":"iOS",
"application_lang_market":"ro_RO",
"platform_width":"320",
"device_type":"mobile",
"platform_height":"480"
},
"date":"2020-05-31T09:38:55.087+03:00",
"ssid":"spresso",
"type":"MOBILEPAGELOAD",
"user":{
"anonymousid":"6BC6DC89-EEDA-4EB6-B6AD-A213A65941AF",
"userid":"2398839"
},
"reception_date":"2020-06-01T03:02:49.613Z",
"event_version":"v1"
}
Issue : Following the documentation, I tried to define a simple telegraf.conf file as below:
[[outputs.influxdb_v2]]
…
[[inputs.file]]
files = ["/home/mouhcine/json/file.json"]
json_name_key = "My_json"
#... Listing all the string fields in the json.(I put only these for simplicity reason).
json_string_fields = ["ssid","type","userid","name","value","country","model"]
data_format = "json"
json_query= "events"
Basically declaring string fields in the telegraf.conf file would do it, but I couldn’t get all the fields that are subset in the json file, like for example what’s inside ( params or context ).
So finally, I get to parse fields with the same level of hierarchy as ssid, type, libVersion, but not the ones inside ( params, context, user).
Output : Screen2 ( attachment ).
OUTPUT
By curiosity, I tried to test the documentation’s example, in order to verify whether I get the same expected result, and the answer is no :/, I don’t get to parse the string field in the subset of the file.
The doc’s example below:
Input :
{
"a": 5,
"b": {
"c": 6,
"my_field": "description"
},
"my_tag_1": "foo",
"name": "my_json"
}
telegraf.conf
[[outputs.influxdb_v2]]
…
[[inputs.file]]
files = ["/home/mouhcine/json/influx.json"]
json_name_key = "name"
tag_keys = ["my_tag_1"]
json_string_fields = ["my_field"]
data_format = "json"
Expected Output : my_json,my_tag_1=foo a=5,b_c=6,my_field="description"
The Result I get : "my_field" is missing.
Output: Screen 1 ( attachement ).
OUTPUT
By the way, I use the influxdb cloud 2, and I apologize for the long description of this little problem, I would appreciate some help please :), Thank you so much in advance.
