    Default Custom module to count how much traffic users have done in a X range of seconds

    I am currently trying to build a module to improve accounting of the streams made by Wowza.

    Software versions used to build this module:
    Wowza version: 4
    JDK: 1.8

    Rationale:

    I want to build a module that:

    • Counts how much traffic users have done in a range of seconds e.g 10 (disconnect/stop should count as well)
    • Available for RTMP, RTP(RTSP) and HTTP (HLS/HDS/DASH/Smooth)



    Problems:

    I would like to know what is a proper way to count all those protocol in the same module.

    What I have so far:

    Hello

    One example would be to check out our connection counts http provider.

    Thanks

    Would I be able to count traffic (bytes) with that example if using JWPlayer? (rtmp://[wowza-ipaddress]/.../live.sdp)

    Do you see any problem with this?
    I am not sure if this is the best way to uniform RTMP, RTP, HTTP in one module.

    Now I get what you meant talking about HTTPProvider.

    Implementing something like that, how to avoid the HTTP overhead? Is there any way to use that module (example provided in the link) without the HTTP overhead? Like calling from other class? There is the timer (range of seconds) problem too. What are your thoughts?
