♒ aquarius

aquarius is a tool for load-testing http/2 servers.

🏃 running instructions

🐚 shell script

the easiest way to see this program run is via the demo script. run it via:

; ./run.sh

🤖 just

a justfile is provided, with commands to run a test server and run a load test against that local server. you can choose from other actions via fzf by running just, with no arguments.

starting a local server

; just run-test-server

running a load-test against the server

; just run-load-test

you may also use cargo run to run the aquarius binary.

; cargo run -- --rate 64 --total 1024 localhost:8080

open library documentation

just doc-open

🤓 nix shell

nix users can run nix develop to enter a development shell that compiles the aquarius binary and adds it to the $PATH. otherwise, cargo build will suffice.

; nix develop

Usage: aquarius [OPTIONS] <SERVER>

Arguments:
  <SERVER>
          the address of the server to be load-tested.

          this should be provided in the form of a `hostname:port` pair.

Options:
      --total <REQUESTS_TOTAL>
          the number of requests to send to the server

      --rate <REQUESTS_PER_SECOND>
          the rate at which to send requests to the server

      --show-charts
          if true, render ascii charts after finishing

      --trace
          if true, configure a [`tracing`] subscriber.

          these logs will be written to stdout.

  -h, --help
          Print help (see a summary with '-h')

💹 rendering charts

if the --show-charts option is provided, some ascii charts will also be rendered. by default, this is false.

🔬 tracing logs

aquarius will emit tracing logs on stderr if the --trace option is provided. by default, this is false.

❗ usage disclaimer

orienting a load-tester at infrastructure you do not control can be considered a denial-of-service (DoS) attack. be sure to point aquarius at your own servers.
