Siege Executor

About

Siege is an HTTP load testing and benchmarking utility. Taurus supports the following Siege features:

  • CONCURRENT (concurrency in Taurus terms): number of simulated users (default 1),
  • URL-FILE(script): a file with a list of target URLs. Taurus allow you to set variables for this file,
  • INTERNET & DELAY: randomly hitting of url-file with some delay if you set it with think-time option,
  • BENCHMARK: throughput test if think-time option is not found,
  • HEADER(headers in config file): set HTTP headers for request,
  • REPS(iterations): repeat requests N times,
  • TIME(hold-for): set execution time limit.

Please keep in mind these rules when using Siege test executor:

  • You must specify at least one URL with url param in requests section or as url-file (script).
  • It's required to explicitly set either iterations or hold-for limit.
  • If you use script option - no variables or requests will be used.
  • You need to have Siege installed. If siege isn't in the system PATH - you can specify the path to Siege binary with path option.

Configuration Examples

Simplest working example - use it to get taste of the tool.

execution:
- executor: siege
  concurrency: 3 
  iterations: 10
  scenario: simplest

scenarios:
  simplest:
    requests:
    - http://blazedemo.com/

Five repeats by hundred of users without any delay (might hurt the server):

execution:
- executor: siege
  concurrency: 100
  iterations: 5
  scenario: simplest

scenarios: 
  simplest:
    requests:
    - http://blazedemo.com/

Test URLs from nodes.list file with 50 users, hold load for 5 minutes

execution:
- executor: siege
  concurrency: 50
  hold-for: 5m
  scenario: external_urls
  
scenarios:
  external_urls:
    think-time: 15s
    script: ~/tests/nodes.list

Variables example:

scenarios:
  variables_usage:
    requests:
    - variables:
      - HOST0: 'http://mainhost.com/'
      - url: '$(HOST0)page1.html'
      - url: '$(HOST0)dir/page2.html'

Module Settings

If you have Siege in non-standard location, please use path option to point Taurus to siege binary:

modules:
  siege:
    path: /home/user/sources/siege/bin/siege
