MQTT monitoring with PRTG

5 reasons why to choose PRTG as your MQTT monitoring tool

As Message Queuing Telemetry Transport (MQTT) has become one of the most important protocols in the IIoT and IoT world, it should also be a key component of your monitoring concept. The solution: Paessler PRTG, your all-in-one monitoring tool that combines IT, industrial IoT, and OT network monitoring in a single pane of glass.

View from a central dashboard

Do away with checking IT and IoT devices with multiple tools and on multiple dashboards. With MQTT integration in PRTG, you get a combined overview of your classic IT and MQTT devices – all in one place.

What’s more: The PRTG Map Editor functionality lets you easily create custom dashboards using drag and drop so that you have the status of all your critical devices and applications at a glance.

Monitor converged IT/OT networks

In industrial IT environments, many OT network components such as PLCs, industrial PCs, SCADA systems, HMIs, or MES cannot be monitored with traditional IT monitoring protocols.

PRTG’s MQTT monitoring, in combination with your smart industrial gateways, easily brings OT network data into your IT monitoring concept.

Benefit from out-of-the-box integrations

Beyond support for all classic IT standards, PRTG offers a RESTful API, JSON, and MQTT support out of the box.

Not to mention OPC UA and SCADA integration to easily monitor shop floors, IoT devices, and other IT devices, applications, and services that don't use common IT technologies.

Get full MQTT server monitoring

No need to worry whether a connection to the MQTT broker – or server – can be established, or if it accepts messages or forwards them to a matching subscriber at all.

With PRTG’s preconfigured sensor types for monitoring MQTT, you can keep an eye on the availability and connection time of your MQTT broker 24/7.

Receive custom alerts & notifications

Set it – that is, thresholds – and forget it. With PRTG’s real-time alerts and customizable notification templates, you’re always notified in time if there is an issue in your infrastructure.

Use MQTT notifications, for example, to forward alerts, warnings, or any other information to a third-party system of your choice that can subscribe to MQTT topics.

How MQTT monitoring with PRTG works

PRTG comes with more than 250 preconfigured sensor types out of the box for monitoring your IT, OT, and IoT infrastructures on all levels – from hardware to applications, from on-prem installations to cloud and virtual environments. For MQTT monitoring, there are 3 native sensors that allow you to monitor everything that communicates via MQTT.

MQTT Round Trip

The MQTT Round Trip sensor monitors the availability of an MQTT broker, connects to the broker as a publishing and subscribing client, and sends the data packets using a predefined topic. It can show the following:

• The time it takes the publisher to connect
• The RTT of the message (after both publisher and subscriber connect)
• Round trip status
• The time it takes the subscriber to connect

MQTT Statistics

The MQTT Statistics sensor monitors an MQTT topic. It can show the following:

• Number of active MQTT topics
• Number of messages received since the last scan
• Received payload

MQTT Subscribe Custom

The MQTT Subscribe Custom sensor subscribes to an MQTT topic and monitors up to ten custom numeric values from the received JSON data. It can show the following (examples only):

• Temperature
• Humidity
• Illuminance
• Pressure
