AB (Apache benchmark) pressure test

Recently used to the next AB, the original written to turn out, paste it out, make a record.

AB (Apache Benchmark) is Apache's own performance testing tool in Apache's Bin directory.

With CMD into Apache's Bin directory, this example takes Apache under Windows as an example.

C:\Program Files\apache Software foundation\apache2.2\bin>

Format: AB [options] [http://]hostname[:p Ort]/path

Parameters:

-N requests number of requests to perform

The number of requests executed in the test session. By default, only one request is executed

-c concurrency number of multiple requests to make

The number of requests produced at one time. The default is one at a time.

-T TimeLimit Seconds to Max. Wait for responses

The maximum number of seconds the test takes. Its internal implied value is-n 50000. It allows you to limit the testing of the server to a fixed total time. By default, there is no time limit.

-P postfile File containing data to POST

A file that contains the data that needs to be post.

-T Content-type content-type header for POSTing

The Content-type header information used by the post data.

-V verbosity how much troubleshooting info to print

Setting the level of detail to display information-4 or greater displays header information, 3 or greater values can display response codes (404, 200, etc.), and 2 or greater values can display warnings and other information. -V Displays the version number and exits.

-W Print out results in HTML tables

Outputs the result in the format of an HTML table. By default, it is a table with a two-column width on a white background.

-I use HEAD instead of GET

Executes the head request instead of get.

-X attributes String to insert as table attributes

//

-Y attributes String to insert as TR attributes

//

-Z attributes String to insert as TD or TH attributes

//

-C attribute Add cookie, eg. ' Apache=1234. (repeatable)

-C Cookie-name=value attach a cookie to the request: line. Its typical form is a parameter pair of Name=value. This parameter can be repeated.

-H attribute Add arbitrary header line, eg. ' Accept-encoding:gzip '

Inserted after all normal header lines. (repeatable)

-A attribute Add Basic WWW authentication, the attributes

is a colon separated username and password.

-P attribute Add Basic Proxy authentication, the attributes

is a colon separated username and password.

-P Proxy-auth-username:password provides a Basic authentication trust to a transit agent. The user name and password are separated by a: and sent in Base64 encoded form. This string is sent regardless of whether the server is required (that is, if the 401 authentication requirement code is sent).

-X Proxy:port ProxyServer and port number to use

-V Print version number and exit

-K Use HTTP KeepAlive feature

-D do not show percentiles served table.

-S do not show confidence estimators and warnings.

-G filename Output collected data to gnuplot format file.

-e filename Output CSV file with percentages served

-H Display Usage information (this message)

-attributes the string that sets the property. There are various statically declared fixed-length buffers in the defect program. In addition, parsing of command-line arguments, the response headers of the server, and other external inputs can be very simple, which may have undesirable consequences. It does not realize the http/1.x completely; Accept only certain ' expected ' response formats. The frequent use of STRSTR (3) can lead to performance problems, that is, you may be testing the performance of AB rather than the server.

A lot of parameters, generally we use the-C and-n parameters can be. For example:

Ab-c 1000-n http://127.0.0.1/index.php

"Under Linux for

./ab-c 1000-n http://127.0.0.1/index.php "

This represents processing 1000 requests at the same time and running the login.jsp file 1000 times.

Ab-c 10-n http://10.14.132.35:8080/cs/user/login.jsp

Under Window for

C:\Program Files\apache Software foundation\apache2.2\bin>ab-c 100-n

The commands under Linux are:

#/usr/local/apache2/bin/ab-c 1000-n http://192.168.1.175:8080/cs/user/login.jsp "
