ali

Release Go Reference

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

Screenshot

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.

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 (rate=50, duration=10s).

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.
      --cacert string              PEM ca certificate file
      --cert string                PEM encoded tls certificate file to use
  -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 stringArray         A request header to be sent. Can be used multiple times to send multiple headers.
      --insecure                   Skip TLS verification
      --key string                 PEM encoded tls private key file to use
      --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.
      --query-range duration       The results within the given time range will be drawn on the charts (default 30s)
  -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)
      --redraw-interval duration   The time interval to redraw charts (default 250ms)
      --resolvers string           Custom DNS resolver addresses; comma-separated list.
  -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)

Examples:
  ali --duration=10m --rate=100 http://host.xz

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

Examples

For basic usage:

ali --rate=500 --duration=5m http://host.xz

For an infinite attack:

ali --duration=0 http://host.xz

For an attack with the POST method:

ali --body-file=/path/to/foo.json --method=POST http://host.xz

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.

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.
