Ensuring a Quality End User Experience

Multimedia and interactive websites built on Flash, Active X, and Silverlight are central to many businesses and marketing teams depend on the experience these web pages and websites create to attract and retain customers. When these flash-enabled web pages are unavailable or slow, business suffers and consumers turn their attention elsewhere.

Use Case Details

In our use case, a gaming company has video trailers for their three top games on their company homepage. With thousands of visitors each day, these videos help convert prospective gamers to new subscribers. When they don't work, business suffers. Let's use AlertFox to see what's causing the problem.

With AlertFox You Know First

To prevent loss of business, The IT team needs to know the moment a delay or outage occurs, so that they can respond quickly and restore the web page service quality. With real-time notifications (SMS or email) provided by AlertFox, the IT team can stay on top off any website performance issues.

How does AlertFox monitor video buffering speed?

AlertFox uses an image recognition technology to verify the video is working correctly. It can measure the time from the page load until the video starts to play, and alert you if there is a problem or a delay. You can also use AlertFox to check on other events, such as the Flash player itself loading on the website.

The Sensor Detail Log

From our email notification we can drill down into the sensor details and see where the error was detected (in this case the United States) and the sensor details show us what went wrong with the monitored transaction. The IT team can now make the necessary changes to restore service quality.

What could cause a problem with video buffering?

Video buffering delays could be caused by a number of reasons including:

    CPU Limitations: CPU limitations would most likely cause the streaming to stop because if the buffer is full, it means also that other buffers will be full.
    Internet Bandwidth Client Side: The internet on the client side is too slow. It can connect to the server, but it can't send at the full bandwidth out, causing a buildup in the buffer.
    Internet Bandwidth Server Side: The internet on the server side is too slow. It's connected to the server, but the server is at full capacity and can't handle more bandwidth, causing the buffer to grow.
    CPU Server Side: The server is too busy with other requests and is not able to handle the incoming traffic.
    Distance Between Server and Client: When the distance between a server and a client is too large it could also fill the buffer.
