We’ll use a very simple test plan :

Note that the thread parameter values are hardcoded here, but we would need to change the values to use properties set by Flood so that they can be set from the Flood user interface.

JMeter Threads

In UbikLoadPack streaming sampler we just set

  • Playlist URL to the HLS manifest URL (we use a property MANIFEST_URL to be able to modify it from outside of JMeter, it defaults to our Mock server “http://localhost:8080/hls/live/test.m3u8“)
