Data Visualization Thoughts about QOS Pie Charts

    Three proposals. Self-evident, yes?

    1. In the Connections Chart, add a line like this:

    [234] connections idle [5] seconds [show]

    Those 234 idle connections are then excluded from the display.

    If you click on [234] you see the details on those idle connections.
    If you click on [5] you can change the threshhold of "idle".
    If you click on [show] the display changes to:

    [hide idle connections]

    and all connections are included, as they are today.

    I would put this line on the same line as the "Total" line.

    2. In the Outbound Chart, add this to the Total line:

    23% of limit=620 kbit/s

    3. In the Inbound Chart, add this to the Total line:

    45% of limit=3210 kbit/s Dropped nnn kbit/s nn kB/s.

    . . .

    Alternatively, here is a more substantial proposal for Outbound and Inbound:

    In the columns, make the %-ages relative to the bandwidth limit. Then, on the Total line, it will not say 100%, but the actual %-age utilization.

    Drop the kbit/s column in the Pie Charts display, and add a "Limit" column. Then we can see directly how the actual utilization relates to the limit for each class.

    I propose dropping kbit/s everywhere, using only kB/s.

    The charts will look more meaningful.
    Now they are very misleading.

    But most people here are programmers and users, not designers and thinkers.
    And everyone is too busy with their practical problems to think about meaning.

    Give it time. :)

    I think this is an important change guys! The charts are misleading and contribute to some of the mass confusion relating to QOS.

    If the graph is mostly unused bandwidth, great! That's what is the actual current network state and it clearly shows that QOS isn't doing much at that moment.

    Right now there are a few of us working on a Tomato build called EasyTomato (designed for nontechnical users in developing countries) and in our build are going to go a step further. We are likely going to make all of the bandwidth graphs to have a static Y axis that is either your QOS max or the max throughput of the connection. This way, we won't confuse non-technical users into thinking there is high activity of the connection (or a specific client) because the graph looks full.

    So just wanted to bump thinking about how to display data in a meaningful way!! :)
