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.

Instalasi

apt-get install openload

Download

cd /usr/local/src/
wget http://sourceforge.net/projects/openwebload/files/openload/0.1.2%20linux/openload-0.1.2.tar.gz

Instalasi

Lakukan

cd /usr/local/src/
tar zxvf openload-0.1.2.tar.gz 
cd /usr/local/src/openload-0.1.2
./configure
make
make install

Menjalankan

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.
