    Default Load test for recording doesn't seem to work

    I'm trying to see how many simultaneous webcam recording sessions our Wowza Server can support. I am following the instructions here:

    The performance.bat file seems to run, but I'm not getting any traffic to the server. Here's the output of performance.bat:

    C:\Program Files (x86)\Wowza Media Systems\Wowza Streaming Engine 4.1.1\bin>performance.bat record-test
    Tuning:  -Xmx10000M -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:NewSize=512m -server -Xmx3000M
    Configure logging: file:///C:/Program Files (x86)/Wowza Media Systems/Wowza Streaming Engine 4.1.1/conf/

    INFO server comment - Status running:0 currBehind:0
    INFO server comment - Status running:0 currBehind:0
    ... and more lines like this

    What do I do to troubleshoot?

    Never mind. The PDF on the Wowza site is actually out of date and doesn't match the PDF that came with the load test tool (!). I followed the instructions in the new PDF and here
