MQTT benchmarking tool
A simple MQTT (broker) benchmarking tool.
Installation:
go get github.com/krylovsk/mqtt-benchmarkThe tool supports multiple concurrent clients, configurable message size, etc:
> mqtt-benchmark --help
Usage of mqtt-benchmark:
-broker="tcp://localhost:1883": MQTT broker endpoint as scheme://host:port
-clients=10: Number of clients to start
-count=100: Number of messages to send per client
-format="text": Output format: text|json
-password="": MQTT password (empty if auth disabled)
-qos=1: QoS for published messages
-quiet=false : Suppress logs while running (except errors and the result)
-size=100: Size of the messages payload (bytes)
-topic="/test": MQTT topic for incoming message
-username="": MQTT username (empty if auth disabled)NOTE: if
count=1orclients=1, the sample standard deviation will be returned as0(convention due to the lack of NaN support in JSON)
Two output formats supported: human-readable plain text and JSON.
Example use and output:
> mqtt-benchmark --broker tcp://broker.local:1883 --count 100 --size 100 --clients 100 --qos 2 --format text
