Json array with no keys

Telegraf
1

I would like to use jsson_v2 objetcs to read an json aray like this, where are no keys defined:

{ “_ULN”: [[
229.5893,
230.2776,
233.334,
223.2332,
230.9603],“V”]}

I tried a lot of different options of the telegraf config file, no success.
Can somebody please point me in the right direction?
Thanks chris

@cnbnjn JSON arrays don’t have keys. To reference elements of an array, you reference the index of the element. So, let’s say to get the first value in the array, GJSON query path would be:

_ULN.0.0

Hi Scott, thanks a lot for your answer.
That will work perfectly fine if the number of elements is always the same.
Any chance to work with an object, so I can read all the elements, even if the number would not always be the same?
