InfluxDB: Flux - Query remote InfluxDB

InfluxDB 2.x can query remote InfluxDB sources with the Flux function from().
From() can retrieve data from remote InfluxDB OSS 1.7+ or InfluxDB Enterprise 1.9+ data sources but not the opposite way.

To query remote InfluxDB sources, include the host, token, and org (or orgID) parameters.

Example

token = "<YOUR_TOKEN>"

from(
  bucket: "<YOUR_BUCKET>",
  host: "https://<YOUR_INFLUXDB-INSTANCE>:8086",
  org: "<YOUR_ORGANISATION>",
  token: token
)
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r._measurement == "<YOUR_MEASUREMENT>")
  ..
