Siege is a utility for stress testing webservers. It was created to
give developers the ability to check the resource consumption of its
code in conditions close to real. Siege also can use the site to
simulate multiple users.

Startup Parameters

Format launch Siege following: “siege options”. The program can take the following parameters:

‘-V’
‘-Version’

Displays the current version.

‘-H’
‘-Help’

Displays help.

‘-C’
‘-Config’

Displays the current configuration. Siege reads the configuration and
displays their contents. You can change them by editing the file $ HOME /
.siegerc.

‘-V’
‘-Verbose’

A detailed derivation of the information. If this option is enabled
Siege will display detailed information on all calls to the server. It
includes the type of HTTP-protocol, the response code and address of the
treatment. Example:

HTTP/1.1 200 OK: / cgi-bin/whoohoo.cgi? First = Homer & last = simpson

This option is especially useful in the case of regression or
simulate the Internet, when the program goes to a wide range of
addresses.

‘-G URL’
‘-Get URL’

Commits an address to the link. Gets the headers from the server and
displays them on screen. It is a great tool for spot testing.

‘-C NUM’
‘-Concurrent = NUM’

Number of simulated users. Option allows you to test your Web server with the number of concurrent users specified in NUM.

‘-I’
‘-Internet’

This option is used with a configuration file containing lots of links.
When you turn it on Siege randomly selects addresses complaints and
makes inquiries to them.

‘-T NUMm’
‘-Time = NUMm’

Time for which the testing should be run. Is in the form «NUMm», where
NUM is the number of units of time, and «m» is a modifier S, M, or H for
seconds, minutes and hours respectively.

‘-F FILE’
‘-File = FILE’

The configuration file contains references (SIEGE_HOME / etc /
urls.txt). You can use this option to specify a different path. For
example:

siege-file = serverb.txt

‘- L’
‘-Log’

This option specifies the Siege that it must record all information in
the log file SIEGE_HOME / var / siege.log. With each new test file will
be appended.

‘- M MESSAGE’
‘-Mark = MESSAGE’

This option allows you to specify an expression which will divide a
record of different testing in the log file. Together with this it is
not necessarily use the option-l, because it will be included
automatically. If the expression contains spaces in the MESSAGE not
forget to put it in quotes.

‘-D NUM’
‘-Delay = NUM’

This option specifies the delay between calls simulated users to the
server. The delay time is calculated from the unit before the
introduction of a number.

Configuration file

Starting with version 2.00 Siege supports configuration files in
which you can store frequently-used commands. This can help a lot of
testing with almost the same settings. This file is called .Seigerc and
is located in your home directory user to install Siege.

Format of transmitted URL

Siege understands the following format options:

[Protocol: / /] [server.domen.xxx] [: port] [/ dierktoriya / file]

Addresses are supported only with HTTP and HTTPS. At least you have
to specify the server name. If you’re inside of a domain name and test
server named shemp, and it’s in your hosts file or in the local DNS,
then the command “Siege-u shemp” make an appeal to address
shemp.domen.net / index.shtml. If you want Siege worked with
https-server then you need to specify an additional and protocol. Thus
the command “siege-u https: / / shemp” make the program contact us at
https: / / shemp.yourdomain.net / index.shtml.

File with other links

Before running regression test or simulation mode Internet you need
to pass the program a list of verifiable addresses. To do this place
them in a file SIEGE_HOME / etc / urls.txt. It addresses must be placed
one per line:

homer.whoohoo.com / howto.jsp
homer.whoohoo.com / index.jsp

homer.whoohoo.com / cgi-bin / hello.pl? first = bart & last = simpson

etc.

Variables

Beginning with the release of version 2.57 Siege supports the
declaration of variables in the file. Siegerc and files with links
(urls.txt). The syntax of declaring of variables Siege is similar to the
syntax of UNIX shell. They announced one per line in the format
“varname = value”

Variable name is placed into the $ () or $ {}. You can use them e.g. for fast switching between the two protocols checked links:

PROT = https: / /
$ (PROT) eos.joedog.org / siege / index.php

$ (PROT) eos.joedog.org / wacky / index.php

$ (PROT) eos.joedog.org / scout / index.php

$ (PROT) eos.joedog.org / libping / index.php

$ (PROT) eos.joedog.org / gunner / index.php

In this example to change the protocol of all links you need to change just one line.

Log File

When Siege starts with the option of logging [-l/--log], the program
puts all output in PREFIX / var / siege.log, where PREFIX – install
directory Siege (see the file INSTALL). In the log file is written that
all program output to the screen in standard mode. Information when
writing is comma-delimited for easy import into other formats.

Platforms

Multi-threaded Siege was assembled and successfully tested extensively on the following platforms:

* AIX (powerpc-ibm-aix4.2.1.0). Siege compiled and tested successfully using the compiler “IBM C for AIX” version 5.
* GNU / Linux (i [56] 86-pc-linux-gnu). Siege was developed on SuSE GNU / Linux with gcc.

* HP-UX (hppa2.0w-hp-hpux11.00) Siege was compiled on this platform using the “HP ANSI C compiler”, and gcc.

* Solaris (sparc-sun-solaris2. [678]) Siege loves this platform. It was normally compiled on it using gcc.

* Microsoft Windows (pc-i686-cygwin) Siege has been ported to Cygwin
Funkman `om. It is normally run all versions of Siege after 1.5.
