brief introduction

Siege is a high-performance, open source HTTP stress testing tool designed to evaluate the stress tolerance of WEB applications. Siege supports authentication, cookies, HTTP, https and ftp protocols. According to the configuration, multiple users can access a WEB site concurrently, record the response time of all requests of each user, and repeat it under a certain number of concurrent accesses.

Siege can request random URL s from the preset list you choose, so siege can be used to simulate user request load, while ab cannot. But don't use siege to perform the highest performance benchmark tuning test. This aspect ab is much more accurate.

Siege supports multiple links, get and post requests, and can conduct multiple stress tests on the web system and send continuous requests.

       siege [options] URL
       siege -g URL
Options:
  -V, --version             VERSION, prints the version number.
  -h, --help                HELP, prints this section.

  -q, --quiet               QUIET turns verbose off and suppresses output.
  -g, --get                 GET, pull down HTTP headers and display the
                            transaction. Great for application debugging.

Parameter details:

• -C. Or -- config prints and displays the current configuration on the screen. The configuration is included in the configuration file $home / In siegerc, you can edit the parameters so that every siege will run according to it
• -v detailed operation information can be seen during operation
• -C, N, or -- concurrent=n simulate that n users are accessing at the same time. N should not be set too large, because the larger the size, the more resources of the local machine are consumed by the siege. The number of concurrent users is 10 by default. Note: by default, the siege only supports 255 concurrent users. You can customize it and modify / root / siege/siege. limit value under conf.
• -i. -- random Internet access URLs Txt to simulate the real access situation (randomness), when URLs Txt is valid when it exists. Simulate network users to randomly click the URL
• -D, N, -- delay = n hit delay between each url, between 0-n
• -r n,--reps=n repeat the test n times, r and t cannot be used at the same time
• -t n,--time=n continuously run siege 'n' for seconds (e.g. 10S), minutes (10M), hours (10H)
• -l after running, save the statistical data to the log file siege Log, usually located in / usr / local / var / siege Log, or in Custom in siegerc
• -R SIEGERC,--rc=SIEGERC specifies to run with a specific siege configuration file. The default is $home / siegerc
• -f FILE, --file=FILE specifies to run siege with a specific urls file. The default is urls Txt, located in etc/urls.txt under the siege installation directory txt
• -5. -- version print version number
• -h. -- help print help information
• -g. -- get pull http header information
• -p. -- print prints the contents of the entire page
• -b. -- benchmark request has no delay
• -H. -- header = "text" add a header to a request. Multiple headers are supported
• -A. -- user agent = "text" set user agent for request
• -T. -- content type = "text" set the content type for the request

Test multiple URLs

Usage example:

siege -c 200 -t 10S -i -d 1 -f url.txt

Note: - c is the concurrency and - t is the time. url.txt is a text file. Each line is a URL, which will be accessed randomly.

url.txt file is as follows:

• Randomly select URLs Txt

siege -c 200 -r 100 -f urls.txt -i
