Wowza data loss reporting and analysis

We all know that data transmission is far from being perfect. Since media data transmission operates with huge amounts of data, most streaming companies face with losses problem, especially within peak hours.

WMSPanel Wowza reporting service may help finding and visualizing problems like that. Let's see typical peak hour using detailed reports.

When you are logged into Dashboard, you can first see real time chart and then after scrolling down it shows 4 retrospective charts for Wowza. First one is "Total connected vs. Bandwidth" that allows seeing peak statistics.

See that blue cliff in front of red mount? That's total connections per 15 minutes interval shown in comparison with average bandwidth.


Now let's look at the traffic:

We would recommend using one of existing CDNs to lower the load of your transmission server. This allows concentrating your resources and staff on a good content or clients' needs rather than thinking about upgrading your network assets. It also gives opportunity to provide your media to the client in different regions without loosing the transmission quality.

Please notice that lots traffic can be calculated for binary protocols only, like RTMP.
