The HiveMQ Sparkplug Extension can be leveraged to gather sparkplug metrics from HiveMQ and persist them into a InfluxDB database. This database can be used as the data source for a monitoring dashboard to monitor directly the data from the devices and gateways of a Sparkplug Infrastructure.
This extension is not yet ready for production use.
If you want use this in production, please contact HiveMQ contact@hivemq.com
Installing the extension for HiveMQ is very easy:
-
Unzip the downloaded zip file
-
In the folder
hivemq-sparkplug-extension
, modify thesparkplug.properties
file to fit your needs. Check that the mandatory properties for influx db (host, port) are set -
Copy the folder
hivemq-sparkplug-extension
to your[HIVEMQ_HOME]/extensions
folder -
Done
The Sparkplug Monitoring extension uses its own configuration file sparkplug.properties
.
The extension won’t start if this file is missing or the required properties are not set.
2 InfluxDB example dashboards are provided in the deploy
subfolder of this extension.

If you don’t already have an InfluxDB 2.0 instance set up, here is a instruction how to start and configure an InfluxDB instance with Docker.
-
Download and install Docker for your platform
-
Start an InfluxDB docker container with the command
docker run -p 8086:8086 -v $PWD:/var/lib/influxdb influxdb
. For more information about using InfluxDB with Docker visit the official Docker repository for InfluxDB -
A local instance of InfluxDB should be running with the port for the database set to 8086
-
The initial setup process for InfluxDB walks through creating a default organization, user, bucket, and Admin authentication token. The setup process is available in both the InfluxDB user interface (UI) and in the influx command line interface (CLI).
-
UI Setup - With InfluxDB running, visit localhost:8086.
-
Click Get Started
-
Set up your initial user
-
Enter a Username for your initial user.
-
Enter a Password and Confirm Password for your user.
-
Enter your initial Organization Name.
-
Enter your initial Bucket Name.
-
Click Continue.
-
-
Done
The Extensions actual supports the Sparkplug B specification for payload. The sparkplug schema is defined with protobuf.
After the extension is installed and an InfluxDB instance exists.
-
Start HiveMQ
-
Extension successfully started if configuration file exists and contains required properties
For testing purposes a simple HiveMQ docker file with the sparkplug extension and a compose file for influxDB setup is available in the deploy/docker subfolder. Further a Kubernetes script for deploying hivemq with sparkplug extension setup in Kuberntes is available in the deploy/k8s
