Random

Description

Emits a randomly generated value on every polling interval. Useful for exercising the pipeline and Destinations without any robot infrastructure — the simplest possible Measurement plugin, and a deterministic, infrastructure-free Record source for load and backpressure testing.

Parameters

Parameter	Description	Type	Default
type	Type of the generated value: `integer` or `double`	str	"integer" (Optional)
min	Minimum value (inclusive) of the generated range	double	0.0 (Optional)
max	Maximum value of the generated range (inclusive for `integer`, effectively exclusive for `double`). Must be greater than min	double	100.0 (Optional)
seed	Seed for the random number generator. A negative value seeds from a non-deterministic source; a non-negative value makes runs reproducible	int	-1 (Optional)
