VitalPBX-Asterisk Stress Test

VitalPBX-Asterisk Stress Test

In this tutorial, we will show you how to perform a test to know the capacity of simultaneous calls in VitalPBX and Asterisk PBX depending on the hardware.

For a long time many people have asked us the following:
“What is the concurrent call capacity of VitalPBX or Asterisk?… What is the bandwidth consumption for calls in VitalPBX or Asterisk?”

We took on the task of conducting an investigation of how to perform a test of concurrent calls and we realized that the information was very poor and did not meet our expectations. So we decided to make a script to test the capacity of concurrent calls in VitalPBX depending on the hardware it has been installed on and bandwidth consumption...

Prerequisites

To do this test it is necessary to have two VitalPBX servers installed, the server on which we will perform the tests and the remote server to which we will connect. It should be noted, that it is necessary that the remote VitalPBX server should have more capacity than the local one. Because if it had less capacity, it will not stress test the maximum capacity of the local server.

Script VitalPBX V3 and V4

Next, copy and run the following script on the server you wish to stress test

[root@vitalpbx1 ~]# cd /
[root@vitalpbx1 ~]# wget https://raw.githubusercontent.com/VitalPBX/VitalPBX-Stress-Test/master/stress-test.sh
[root@vitalpbx1 ~]# chmod +x stress-test.sh
[root@vitalpbx1 ~]# ./stress-test.sh

Set up the following information (In your case the values can change):

IP Local....................................... > 192.168.30.10
IP Remote...................................... > 192.168.30.20
SSH Remote Port (Default is 22)................ > 22
Network Interface name (ej: eth0).............. > eth0
Protocol (1.-SIP, 2.-IAX)...................... > 1
Codec (1.-None, 2.-G79, 3.- GSM)............... > 1
Recording Calls (yes,no)....................... > no
Max CPU Load (Recommended 90%)................. > 90
Calls Step (Recommended 5-20).................. > 10
Seconds between each step (Recommended 5-30)... > 10

Are you sure to continue with these settings? (yes,no) > yes

Are you sure you want to continue connecting (yes/no)? yes

root@192.168.30.20's password: The root password from Remote Server

Note:
The test cannot last more than 10 minutes due to the duration of the audio. If you want a longer duration, change the audio or add more time to the "demo-instruct" audio on this line on the stress-test.sh script:

asterisk -rx "channel originate Local / 200 @ call-test-ext application Playback demo-instruct&demo-instruct......
