ali

A load testing tool capable of performing real-time analysis, inspired by vegeta and jplot.

ali comes with an embedded terminal-based UI where you can plot the metrics in real-time, so lets you perform real-time analysis on the terminal.

Installation

Binary releases are available through here.

Via Homebrew

brew install nakabonne/ali/ali

Via APT

wget https://github.com/nakabonne/ali/releases/download/v0.5.1/ali_0.5.1_linux_amd64.deb

go get github.com/nakabonne/ali

Via Docker

docker run --rm -it nakabonne/ali ali

Usage

Quickstart

ali http://host.xz

Replace http://host.xz with the target you want to issue the requests to. Press Enter when the UI appears, then the attack will be launched with default options.

Options

ali -h
Usage:
  ali [flags] <target URL>

Flags:
  -b, --body string         A request body to be sent.
  -B, --body-file string    The path to file whose content will be set as the http request body.
      --buckets             Histogram buckets in comma-separated value (example: "10ms, 100ms, 500ms".
  -c, --connections int     Amount of maximum open idle connections per target host (default 10000)
      --debug               Run in debug mode.
  -d, --duration duration   The amount of time to issue requests to the targets. Give 0s for an infinite attack. (default 10s)
  -H, --header strings      A request header to be sent. Can be used multiple times to send multiple headers.
      --local-addr string   Local IP address. (default "0.0.0.0")
  -M, --max-body int        Max bytes to capture from response bodies. Give -1 for no limit. (default -1)
  -W, --max-workers uint    Amount of maximum workers to spawn. (default 18446744073709551615)
  -m, --method string       An HTTP request method for each request. (default "GET")
      --no-http2            Don't issue HTTP/2 requests to servers which support it.
  -K, --no-keepalive        Don't use HTTP persistent connection.
  -r, --rate int            The request rate per second to issue against the targets. Give 0 then it will send requests as fast as possible. (default 50)
  -t, --timeout duration    The timeout for each request. 0s means to disable timeouts. (default 30s)
  -v, --version             Print the current version.
  -w, --workers uint        Amount of initial workers to spawn. (default 10)

Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".

Charts

Press l (or h) to switch the displayed chart. On all charts, you can click and drag to select a region to zoom into.

Latency

The X-axis represents the request counts and the Y-axis represents latencies in milliseconds.

Percentiles

You can see how the 50th, 90th, 95th, and 99th percentiles are changing.

Features

Plot in real-time

Visualize the attack progress

This will help you during long tests.

Mouse support

With the help of mum4k/termdash can be used intuitively.

Acknowledgements

This project would not have been possible without the effort of many individuals and projects but especially vegeta for the inspiration and powerful API. Besides, ali is built with termdash (as well as termbox-go) for the rendering of all those fancy graphs on the terminal. They clearly stimulated an incentive to creation. A big "thank you!" goes out to all those who helped.
