InfluxDB Endpoint Properties

query (string)

The Flux query used for reading or subscribing to measurement data. This property is only applicable for read or subscribe endpoints.

Example: "from(bucket:\"my-bucket\") |> range(start: -1h) |> filter(fn: (r) => r._measurement == \"temperature\")"

interval (integer)

Time interval in milliseconds between consecutive queries. Defaults to 1000 milliseconds if not specified.

cronExpression (string)

Cron expression that defines the schedule for polling the endpoint. For syntax and examples, see the node-cron documentation.

Examples: "1,2,4,5 * * * *", "1-5 * * * *", "*/2 * * * *", "* * * January,September Sunday"

Example: "engine_"
