PRTG: the all-in-one monitoring solution for MQTT


Message Queuing Telemetry Transport (MQTT) is a simple lightweight protocol for transporting messages between devices. It has become one of the most important protocols in the IIoT and IoT making it indispensable for many companies. This importance makes it a key component of your monitoring solution! This is where PRTG Network Monitor comes into play.

PRTG offers IT admins a monitoring solution for all the systems, devices, traffic, and applications in your IT infrastructure. Additionally, PRTG combines the IT and OT world. Among other sensors, PRTG offers 3 native MQTT sensors allowing you to monitor everything that communicates via MQTT:

MQTT Round Trip sensor (beta)

MQTT Statistics sensor (beta)

MQTT Subscribe Custom sensor (beta)

 

The advantages of MQTT Monitoring with PRTG

PRTG Network Monitor's ability to monitor MQTT means that it is an all-in-one monitoring
solution that can combine the IT and OT world in one single overview.

 

 

One overview

MQTT is widely used to communicate with IoT and IIoT devices, and these devices are becoming more a part of IT infrastructure than ever before. With MQTT integration in PRTG Network Monitor, you can have a combined overview of your IT and MQTT devices...all in one place. 

Monitor OT and IT

In industrial IT environments, many OT devices cannot be monitored with traditional IT monitoring methods or protocols, such as Programmable Logic Controllers. However, using a combination of PRTG Network Monitor, MQTT, and smart industrial gateways, you have more options to bring OT data into your IT monitoring concept.

Future proof

Digitalization of industrial IT has brought about an increase in the number of IIoT devices in production environments, from smart gateways through to devices for measuring humidity and temperature. This trend will continue, and MQTT will become more important for accessing data all across the factory – from the production line, through to facility management. 

 

 

 

 

IT/OT convergence with PRTG Network Monitor

PRTG Network Monitor is a world leading IT monitoring solution that combines a broad feature set with outstanding usability and maximum flexibility. Beyond out-of-the-box support for all classic IT standards, PRTG offers a RESTful API as well as JSON and MQTT support to easily integrate shop floors, IoT devices for monitoring environmental parameters, and other IT devices and applications that don't use common standards.

MQTT – how does it work?
 

Devices are able to send messages to each other via:

  • Topics. These are a way of categorizing the types of messages that might be sent. For example: if a sensor measures temperature, the topic might be defined as “TEMP”, and the sensor sends messages out labeled as “TEMP”.
  • Publishers. Devices can be configured to send out messages containing data. Using the temperature example, the sensor measuring temperature publishes this data.
  • Subscribers. Devices or systems can be configured to receive only messages of a specific topic. They can also subscribe to multiple topics.
  • Broker. This is the server that is at the center of it all, which transmits the published messages to servers or clients that have subscribed to specific topics.
 

 

 

What is MQTT?

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol. It is used in cases where a small code footprint is needed while bandwidth resources are limited. It is primarily used for machine-to-machine (M2M) communication or Internet of Things types of connections.

The MQTT sensors
and what they monitor
 

iWhat is a sensor?

In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Built-in alarm features

MQTT Round Trip (beta)

Most importantly, your devices have to be available and transmit data. The broker is the central element within the MQTT communication and should therefore be monitored. With the MQTT Round Trip sensor, PRTG can fully monitor the MQTT broker. In the future, you won't have to worry whether a connection to the broker can be established or if it accepts messages or forwards them to a matching subscriber. The sensor monitors the message round-trip time (RTT), round trip status, publisher connection time and subscriber connection time. Take a look at the PRTG Manual for more details.

 

Built-in alarm features

MQTT Statistics sensor (beta)

Are your devices and the broker sending messages? This sensor knows best and monitors MQTT topics whilst displaying relevant statistics of the broker, like the number of incoming messages from a subscribed topic and the received payload. You can find more details in the PRTG Manual.

 

Built-in alarm features

MQTT Subscribe Custom sensor (beta)

Use this sensor if you want to monitor numerical values returned by received JSON data.

The sensor subscribes to an MQTT topic and monitors up to five numerical values from the received JSON data. The values in the channels can easily be configured according to your needs. Check out the PRTG Manual for more details.

 

These three sensors enable you to monitor everything that deals with MQTT. The sensors are in the beta phase. The operating methods and the available settings can change in the future.

 

Built-in alarm features

PRTG sensors for everything else

Bandwidth monitoring, specific datasets from your database, applications, cloud computing services, all types of servers, and many more... Everything is included in PRTG!
