range() function

The range() function filters records based on time bounds. Each input table’s records are filtered to contain only records that exist within the time bounds. Records with a null value for their time are filtered. Each input table’s group key value is modified to fit within the time bounds. Tables where all records exists outside the time bounds are filtered entirely.

*Function type: Transformation *Output data type: Record*

  1. range(start: -15m, stop: now())

Parameters

start

The earliest time to include in results. Results include points that match the specified start time. Use a relative duration, absolute time, or integer (Unix timestamp in seconds). For example, -1h, 2019-08-28T22:00:00Z, or 1567029600. Durations are relative to now().

*Data type: Duration | Time | Integer*

stop

The latest time to include in results. Results exclude points that match the specified stop time. Use a relative duration, absolute time, or integer (Unix timestamp in seconds). For example, -1h, 2019-08-28T22:00:00Z, or 1567029600. Durations are relative to now(). Defaults to now().

*Data type: Duration | Time | Integer*

Time values in Flux must be in RFC3339 format.
