emqtt-bench VS MQTTX

For installation and usage, please refer to emqtt-bench: Lightweight MQTT benchmark tool written in Erlang

git clone https://github.com/emqx/emqtt-bench.git cd emqtt-bench CMAKE_BUILD_TYPE=Debug BUILD_WITH_QUIC=1 make

With the help of the open-source MQTT performance test tool emqtt-bench, we test whether the client's Pub/Sub has a rate limit.

Originally published at https://www.emqx.com.

For deploying and running our cluster tests, we used AWS CDK, which allowed us to experiment with different instance types and numbers, and also trying out different development branches of EMQX. You can checkout our scripts in this Github repo. In our load generator nodes ("loadgens" for short), we used our emqtt-bench tool to generate the connection / publishing / subscribing traffic with various options. EMQX's Dashboard and Prometheus were used for monitoring the progress of the test and the instances' health.

This section will introduce how to use Neuron to collect data from FINS TCP devices, upload the collected data to EMQX, and view it using MQTTX.

Next, we open MQTTX, create a new connection, copy the JWT output when JWKS Endpoint starts to the Password field, and click Connect in the upper right corner to connect.

Again, we can use MQTTX or any other MQTT client to publish MQTT data to the demo/sensor topic. Those data will be processed by the rule. For example, we publish the following data to the topic with a 30 seconds interval, and the two minutes data is like this:

Among these, the MQTTX open-source project stands out as a fast-growing client tool that offers a modern chat-style interface, full MQTT 5.0 support, and a rich set of features that provides a great user experience. With three versions available - Desktop, Command Line, and Browser - MQTTX can fulfill your MQTT testing requirements in diverse scenarios. Undoubtedly, MQTTX is among the top MQTT client tools of 2023.

Next, we will demonstrate the use of Clean Session with the open-source cross-platform MQTT 5.0 desktop client tool - MQTT X.

MQTT connections are initiated from the client to the broker. Any application or device running the MQTT client library is an MQTT client. The MQTT Broker handles client connection, disconnection, subscribe (or unsubscribe) requests, and routes messages up on receiving publish requests.

MQTT X is an open-source cross-platform desktop client. It is easy to use and provides comprehensive MQTT 5.0 functionality, feature testing, and runs on macOS, Linux and Windows. It also provides command line and browser versions to meet MQTT testing needs in different scenarios.

In this post, we are not going to dig into the programming SDKs. We will try to demonstrate MQTT retained messages using the open-source cross-platform MQTT 5.0 desktop client - MQTT X.

Use MQTT 5.0 client tool - MQTT X as another client to test message sending & receiving.
