Multiple key / value pairs from json

I have a json object like this:
Unbenannt

Is it possible, to push various key / value pairs to influxdb in one input plugin.For example

a
c
f

Many thanks

I made a few assumptions about the input: that you wanted the strings to be tags and that f was an numeric value, and that there would only be one f in the d list. If your actual data is too much more complicated, it may not work out.

{
	"a": "v",
	"b": {
		"c": "v"
	},
	"d": [
		{
			"e": 3
		},
		{
			"f": 4
		}
	]
}

Anyway I came up with this, rather crazy, query:

[[inputs.file]]
  files = ["example.json"]
  tag_keys = ["a", "c"]
  json_query = '{a,b.c,d|#(f!="")#|0.f}'
  data_format = "json"
file,a=v,c=v f=4 1584586995000000000

Thank you!

Do I have to define the fields which are not numbers, as string_fields?

What about, a “dot” in the key name, do I have to escape it?

My config:
[[inputs.http]]
urls = [“url”]
method = “POST”
body = ‘{“identity”: “x”}’
interval = “30s”
success_status_codes = [200]
data_format = “json”
tag_keys = [“IMSI”]
json_query = ‘{mme, subscriber.IMSI}’
timeout= “10s”
headers = {“Content-Type” = “application/json”}
[inputs.http.tags]
influxdb_database = “subscriber_data”

My data:
{
“mme”: “MME88”,
“subscriber”: {
“IMSI”: “x”
}
}

Do I have to define the fields which are not numbers, as string_fields?

Yes, but you can use a glob: json_string_fields = ["*"]

What about, a “dot” in the key name, do I have to escape it?

Should be possible to escape a dot with backslash, the full syntax for json_query is described here: https://github.com/tidwall/gjson/blob/master/SYNTAX.md

Got it working, I’m now pushing the whole data into influxdb.

Thank you!
