HiveMQ InfluxDB Monitoring Extension

Purpose

The HiveMQ InfluxDB Extension can be leveraged to gather metrics from HiveMQ and persist them into a time series database. This database can be used as the data source for a monitoring dashboard (like Grafana) that drills down into the inner workings of HiveMQ and provides valuable insights to your operations team.

Installation

Installing the extension for HiveMQ is very easy:

Unzip the downloaded zip file
In the folder hivemq-influxdb-extension, modify the influxdb.properties file to fit your needs. Check that the mandatory properties (host, port) are set
Copy the folder hivemq-influxdb-extension to your <HIVEMQ_HOME>/extensions folder
Done

Configuration

The InfluxDB Monitoring extension uses its own configuration file influxdb.properties. The extension won’t start if this file is missing or the required properties are not set.

General Configuration

Config name	Required	Description	Default
mode	no	The mode configured for the InfluxDB sender. Possibilities are: http, tcp, udp, cloud	http
host	yes	The host name of the InfluxDB instance.	-
port	yes	The port number the InfluxDB instance is listening.	8086
protocol	no	The protocol the InfluxDB sender uses in http mode.	http (or https for cloud mode)
auth	no	The authorization string to be used to connect to InfluxDB, of format username:password. If mode "cloud" is used, the token must be passed here	-
prefix	no	The measurement prefix.	-
database	no	The database name.	hivemq
reportingInterval	no	The reporting interval in seconds.	1
connectTimeout	no	The connect and read timeout in seconds.	5000
tags	no	The tags for each metric. Listed as a semicolon ( `;` ) separated list.	-
organization	only for mode: "cloud"	The organization to push data to	-
bucket	only for mode: "cloud"	The bucket to push data to	-

Note	When using InfluxDB 2 the *Cloud* mode should be configured.

Example Configuration

mode:http
host:localhost
port:8086
protocol:http
auth:

prefix:
database:hivemq

reportingInterval:1
connectTimeout:5000

tags:host=hivemq1

First Steps

Quick Start InfluxDB

If you don’t already have an InfluxDB instance set up, here is an instruction how to start a not configured 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
Create a database that matches the name set in the property database in influxdb.properties. For the default database value use the command curl -G http://localhost:8086/query --data-urlencode "q=CREATE DATABASE hivemq"
Done

Usage

After the extension is installed and an InfluxDB instance exists.

Start HiveMQ
Extension successfully started if configuration file exists and contains required properties
