Good Point.
> Realistic Time Series Processor Simulator
> -----------------------------------------

> Key: NIFI-4164
> URL: https://issues.apache.org/jira/browse/NIFI-4164
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Chris Herrera
> Assignee: Chris Herrera
> Priority: Minor
> Labels: features
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> In order to validate several flows that deal with sensor data, it would be
> good to have a built in time series simulator processor that generates data
> and can send it out via a flow file.
