# Lightweight MQTT Benchmark Tool written in Erlang
`eMQTT-Bench` is a lightweight MQTT v5.0 benchmark tool written in Erlang.
You can download pre-built binary packeges from https://github.com/emqx/emqtt-bench/releases.
## Build from source code
NOTE: Requires **Erlang/OTP 22.3+** to build.
### Install dependencies
emqtt-bench requires `libatomic`
``` sh
# centos 7
sudo yum install libatomic
```
``` sh
# ubuntu 20.04
sudo apt install libatomic1
```
### make
```sh
git clone https://github.com/emqx/emqtt-bench.git
cd emqtt-bench
make
```
Optional, you could disable QUIC support if you have problem with compiling
``` sh
BUILD_WITHOUT_QUIC=1 make
```

that port. [default: disabled]
```
For example, create 100 connections and each publishes messages at the rate of 100 msg/sec.
```sh
./emqtt_bench pub -c 100 -I 10 -t bench/%i -s 256
```
## Local interface
```sh
./emqtt_bench pub --ifaddr 192.168.1.10
./emqtt_bench sub --ifaddr 192.168.2.10
```
## TLS/SSL (cliet certificate is not required by server)
```sh
./emqtt_bench sub -c 100 -i 10 -t bench/%i -p 8883 --ssl
./emqtt_bench pub -c 100 -I 10 -t bench/%i -p 8883 -s 256 --ssl
```
## TLS/SSL (client certificate is required by server)
```sh
./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
./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 64K for TCP ports limit on one source addresses,
however you can send messages from multiple source IP Addresses with '--ifaddr ' such like
```
./emqtt_bench sub -c 200000 -t "perf/test" --ifaddr 192.168.200.18,192.168.200.19,192.168.200.20,192.168.200.21
```
Make sure to increase resource usage limits and expand the port range like following on Linux.
``` sh
ulimit -n 200000
sudo sysctl -w net.ipv4.ip_local_port_range="1025 65534"
```
