Thread: Best practices for determining load capabilities

    Default Best practices for determining load capabilities

    Hello,

    We're trying to come up with a way to determine the load we can give our Wowza server is. We are primarily just use it as a FMS, sending it a flash stream, and have Wowza produce HLS from that stream.

    I like the idea of using JMX to monitor Wowza, but we don't really have the means to send a massive number of streams at Wowza to see what it can do. Does anyone have any suggestions in this regard?

    When Wowza is just producing an HLS (cupertino) stream, it doesn't really seem to be that intensive on the box. But trying to come up with a good metric so we know how many we can handle at the same time.

    Thanks for your input.

    You can use the RTMP Load Test Tool to generate load. You can request it from here. Documentation comes with the module.

    Hi Lisa,

    Thanks for that.

    However, I believe that would help us determine the load our server could handle of concurrent users trying to pull down the HLS stream.

    We are using Akamai to sit in front of wowza for that. Yes it's a live stream, but we still get some caching benefits from Akamai in this regard.

    What we are really looking for is how many applications we can have running on Wowza concurrently. As in, how many flash streams can we SEND to our wowza server (and have Wowza produce HLS for them) before we hit some sort of limit.

    In our use case, the # of users that will be watching will always be fairly low anyway. We are more concerned with how many streams we can send to wowza to flip to HLS.

    Any idea on how we could simulate that or produce a rough estimate?

    Hi
    The number of incoming streams is approximately 200 on a server that meets the Wowza requirements here,

    System Requirements
    Minimum recommended production hardware CPU :
    Single Quad Core, 3.00 GHz or better
    RAM: 4GB
    Disk: 2 or more in RAID 0 (striping) *On Demand requirement
    Network: 1Gb Ethernet
