Erlang MQTT Benchmark Tool

emqtt_bench is a simple MQTT v5.0 benchmark tool written in Erlang.

Build first

make docker

Connect Benchmark

$ docker run -it emqtt_bench conn --help
Usage: emqtt_bench conn [--help <help>] [-h [<host>]] [-p [<port>]]
                        [-c [<count>]] [-n [<startnumber>]]
                        [-i [<interval>]] [-u <username>] [-P <password>]
                        [-k [<keepalive>]] [-C [<clean>]] [-S [<ssl>]]
                        [--certfile <certfile>] [--keyfile <keyfile>]
                        [--ifaddr <ifaddr>]

  --help             help information
  -h, --host         mqtt server hostname or IP address [default:
                     localhost]
  -p, --port         mqtt server port number [default: 1883]
  -c, --count        max count of clients [default: 200]
  -n, --startnumber  start number [default: 0]

  -u, --username     username for connecting to server
  -P, --password     password for connecting to server

For example, create 100 connections and each publishes messages at the rate of 100 msg/sec.

docker run -it emqtt_bench pub -c 100 -I 10 -t bench/%i -s 256

Local interface

docker run -it emqtt_bench pub --ifaddr 192.168.1.10
docker run -it emqtt_bench sub --ifaddr 192.168.2.10

TLS/SSL (cliet certificate is not required by server)

docker run -it emqtt_bench sub -c 100 -i 10 -t bench/%i -p 8883 --ssl
docker run -it emqtt_bench pub -c 100 -I 10 -t bench/%i -p 8883 -s 256 --ssl

TLS/SSL (client certificate is required by server)

docker run -it emqtt_bench sub -c 100 -i 10 -t bench/%i -p 8883 --ssl --certfile path/to/client-cert.pem --keyfile path/to/client-key.pem
docker run -it emqtt_bench pub -c 100 -i 10 -t bench/%i -s 256 -p 8883 --ssl --certfile path/to/client-cert.pem --keyfile path/to/client-key.pem

Notice

You should not set '-c' option more than 60K for TCP ports limit on one interface.
