When getting data by inputs.http from my solar battery the standard request works fine, but the status request is only partly transferred. The answer is a nested JSON with 5 valuearrays. the second (battery_status) and third (battery_status_units) are vanishing on their way through telegraf.
WHY???
Config of telegraf plugin:
# Read formatted metrics from one or more HTTP endpoints
[[inputs.http]]
## One or more URLs from which to read formatted metrics
urls = [
“http://[URL Of Target]”,
]
name_override = “SonnenBat”
method = “GET”
data_format = “json”
json_time_key = [“Timestamp”]
json_time_format = [“2020-09-26 15:32:16”]
JSON (answer by curl URL) Raw:
