Track end-to-end latency to your MQTT broker

Tracking end-to-end latency (response time) is useful in selecting your
MQTT broker, as well as monitoring your IoT platform / broker performance.

Check this real-time latency dashboard at

http://latency.iotsim.io/

which tracks end-to-end response time every second to a number of
public MQTT brokers over the internet. The local intranet mosquitto broker
measurement is for comparison.

The NODE-RED source code is at

MIMIC MQTT Simulator enables rapid prototyping for Telit IoT Platform

If you want to prototype or test your solution with Telit's IoT Platform, then
you can use MIMIC MQTT Simulator to simulate a large number of sensors
and gateways.

In our initial effort we simulate a single sensor generating programmatic,
customizable, predictable, reproducible telemetry to Telit. With MIMIC what
can be done with one sensor can easily be scaled to thousands or even
millions of sensors. Complex scenarios can be setup once, and reproduced
at will thereafter. You can investigate different choices very quickly.

In the screenshot below, the light value changes randomly, but the
temperature value is changed predictably on-demand at run-time.
