Scripts to test a maximum number of WebRTC publishers/subscribers

Since build 5.2.1766 a scripts are available to test a maximum number of WebRTC publisher or subscribers per WCS server. The scripts are implemented in bash and use REST API to publish and pull WebRTC streams from a WCS server under test. The scripts are in /usr/local/FlashphonerWebCallServer/tools folder.

To perform a load test, the following should be prepared:

  • WCS server to test
  • WCS server to perform the test
  • a tool to publish a source stream (OBS to publish RTMP, or Media Devices example to publish WebRTC)

Attention

Note that the server perfomance to perform the test should be at least twice as the server under test, otherwise the testing server may be a bottleneck.

Testing a maximum number of WebRTC publishers

A maximum number of WebRTC publishers test is performed with the following script

/usr/local/FlashphonerWebCallServer/tools/pushStreams.sh

  1. The following should be used for test:

    • test1.flashphoner.com - WCS server to test
    • test2.flashphoner.com - WCS server to perform the test
    • Media Devices example to publish a source stream

  2. Publish the source stream to the server test2.flashphoner.com

  3. Launch pushStreams script on test2.flashphoner.com

    /usr/local/FlashphonerWebCallServer/tools/pushStreams.sh ws://test1.flashphoner.com:8080 http://test1.flashphoner.com:8081 test loadtest 10
    Where:

    • ws://test1.flashphoner.com:8080 - websocket URL of the server to test
    • http://test1.flashphoner.com:8081 - HTTP REST API URL of the server to test
    • test - the source stream published to the testing name
    • loadtest - the name prefix used to publish streams to the server to test
    • 10 - publishers count
      The script displays a publishers list when successfully launched

  4. Check stream publishers at the tested server statistics page http://test1.flashphoner.com:8081/?action=stat

  5. Launch pushStreams script on test2.flashphoner.com to stop the test

    /usr/local/FlashphonerWebCallServer/tools/pushStreams.sh ws://test1.flashphoner.com:8080 http://test1.flashphoner.com:8081 test loadtest stop
    Where:

    • ws://test1.flashphoner.com:8080 - tested server websocket URL
    • http://test1.flashphoner.com:8081 - HTTP REST API URL of the tested server
    • test - the source stream name published to the tested server
    • loadtest - the name prefix used to publish streams to the tested server
    • stop - keyword to stop the publishers with the parameters above
      The script displays a stopped publishers list when successfully launched

Testing a maximum number of WebRTC subscribers

A maximum number of WebRTC publishers test is performed with the following script

/usr/local/FlashphonerWebCallServer/tools/pullStreams.sh

  1. The following should be used for test:

    • test1.flashphoner.com - WCS server to test
    • test2.flashphoner.com - WCS server to perform the test
    • Media Devices example to publish a source stream

  2. Publish the source stream to the server test1.flashphoner.com

  3. Launch pullStreams script on test2.flashphoner.com

    /usr/local/FlashphonerWebCallServer/tools/pullStreams.sh ws://test1.flashphoner.com:8080 http://test1.flashphoner.com:8081 loadtest 10
    Where:

    • ws://test1.flashphoner.com:8080 - tested server websocket URL
    • http://test1.flashphoner.com:8081 - HTTP REST API URL of the tested server
    • loadtest - the name prefix used to pull streams from the tested server
    • 10 - subscribers count
      Note that script will pull all the streams published on the tested server with a specified number of subscribers per each.
      The script displays a subscribers list when successfully launched

  4. Check stream subscribers at the tested server statistics page http://test1.flashphoner.com:8081/?action=stat

  5. Launch pullStreams script on test2.flashphoner.com to stop the test

    /usr/local/FlashphonerWebCallServer/tools/pullStreams.sh ws://test1.flashphoner.com:8080 http://test1.flashphoner.com:8081 loadtest stop
    Where:

    • ws://test1.flashphoner.com:8080 - tested server websocket URL
    • http://test1.flashphoner.com:8081 - HTTP REST API URL of the tested server
    • loadtest - the name prefix used to pull streams from the tested server
    • stop - keyword to stop the subscribers with the parameters above
      The script displays a stopped subscribers list when successfully launched
