    Don't you guys think it would be great to have a CPU utilization graph? This could be done fairly easy by reading the loadavg's.

    I think it would be a great tool to benchmark various different router brands and also see how much "oomph" your router has left in case of speed issues or say, slow torrents etc. etc.

    There is already a cpu utilization graph: CPU Load (1 / 5 / 15 mins) 0.05 / 0.8 / 0.01

    You just need to visualize the "graph" in your mind. You really don't want me to graph those three points do you? :)

    These numbers represent average values only. They cannot represent the real picture.

    I'm just trying to say those averages are good enough for every unix system out there and "realtime" cpu graphs aren't gonna be any more useful.

    Yes the loadavg's are there, no doubt, but just saying that if there was a "graph" then things would be "nicer", on the other hand, since you are using SVG's a horizontal bar or vertical bar would also work.

    I am not hell bent on a graph, just a visual representation of the loadavg.

    Is that reasonable enought?

    You don't need a CPU utilization graph for these little routers. Generally the CPU utilization is either 0.0x or infinity (crash). Only the packetprotector firmware with all features enabled while swapping to the USB drive seem to use more than 0.0x% of the CPU.

    Not starting an argument but I beg to differ.

    Sometimes when I use torrents, depending on how I have configured the program I can open many connections per torrent.

    If I go to the router I see the loadavg fluctuating depending on the speed of the torrent, other network activity and of course if there is excessive wifi activity.

    So I just wanted to see this as a visual representation that's all.

    I mean yes, in terms of actual help it might not be that much, but it does add value in specific instances.

    Plus a little eye candy does not hurt :)

    The load average is not exactly a CPU graph ...
    read :

    a CPU graph would be very nice, but I guess we would have it already if it was possible and easy (same for memory usage)
