WHAT IS IT?A lightweight mock implementation of Kura

● Framework or ready-to-run application

● Plain Java

● Mock services for e.g. Bundle installation

● Allow custom applications

● Data generation framework

DATA SIMULATIONCreating telemetry data streams

Allows to create streams of time-synced telemetry data with easy scaling

● Multiple application and topics

● Mapping value generators to metrics

● Configured via JSON

● Allow dropping in custom generator implementations

● Create re-producible values for a point in time

TIMESTAMP VALUE

t1 =sine(t1)

t2 =sine(t2)

t3 =sine(t3)

Reproducible values

IT’S LIKE MINECRAFTRe-creating worlds with the same seed
