OpenWebLoad

OpenWebLoad adalah alat untuk menguji beban aplikasi web. Ini bertujuan agar mudah digunakan dan menyediakan pengukuran kinerja yang mendekati real-time dari aplikasi yang diuji. Hal ini khususnya berguna ketika anda melakukan optimasi karena anda dapat melihat dampak perubahan yang anda lakukan sesegera mungkin.

Download

You can download the latest release of OpenWebLoad from SourceForge HERE.

For other systems download the .tar.gz file, unpack it using:

    tar xvzf <filename>

and compile using the normal procedure:

    ./configure
    make
    make install

see the INSTALL file for details. Win32

Download the executable (openload.exe) and save it in a directory which is in your path. You can now start OpenWebLoad from any command (DOS) window.

How do I use it?

OpenWebLoad is (currently) a commandline tool, that you execute from a prompt like this:

    openload [options] http://testapp.site.com 10

The 2 parameters are:

   The url of the web page you want to test.
   Number of simultanous clients to simulate. This is optional and defaults to 5.
   A number of options is also available. See here for a detailed description of all the options.

You will then get output similar to this:

 $ openload localhost 10
 URL: http://localhost:80/
 Clients: 10
 MaTps 355.11, Tps 355.11, Resp Time  0.015, Err   0%, Count   511
 MaTps 339.50, Tps 199.00, Resp Time  0.051, Err   0%, Count   711
 MaTps 343.72, Tps 381.68, Resp Time  0.032, Err   0%, Count  1111
 MaTps 382.04, Tps 727.00, Resp Time  0.020, Err   0%, Count  1838
 MaTps 398.54, Tps 547.00, Resp Time  0.018, Err   0%, Count  2385
 MaTps 425.78, Tps 670.90, Resp Time  0.014, Err   0%, Count  3072

 Total TPS: 452.90
 Avg. Response time:  0.021 sec.
 Max Response time:   0.769 sec

Dimana

• MaTps: a 20 second moving average of TPS.
• Tps: (Transactions Per Second) is the number of completed requests during that second.
• Resp Time: the average response time in seconds for the elapsed second.
• Err: the percentage of responses that was erronous, i.e. didn't return a HTTP 200 Ok staus.
• Count: the total number of completed requests.
• Total TPS is the average TPS for the whole run, i.e. (Total completed requests) / (Total elapsed time).
• Avg. Response time: the overall average response time in seconds.
• Max Response time: the highest response time during this run.

Note: you stop the run by pressing Enter.
