@wiresmith So I'm afraid I have to give you the dreaded "it depends" answer. If I'm trying to find a process/docker/whatever that's using more resources than expected, I probably want a table sortable by all of the various columns, with a combo box to set the window to examine ("average over the last minute/hour/day/week"). If I'm trying to determine what, exactly, is causing that resource use, I probably want some kind of real-time values reporting. Apple's Charts accessibility API does a good job of this: VoiceOver can actually play a beep that pans left/right for one axis, and pitches the beep up/down for the other. There are also tools (though only for Windows) that allow me to monitor the CPU or Ram use of a selected process on the machine, by just playing a constant beep, and changing the pitch up and down as the value changes. This way I can trigger various functions, and see when exactly the use spikes. It can also be useful to be able to set "expected resource use", and then get back a list of timestamps when the value was above or below what I set as the "expected" range. Then, at least, I can start matching up these timestamps with other things happening on the machine (chron jobs? A popular website post? Whatever.). I think the ultimate solution, here, is to get all of the people making these dashboards to use SVG and other standards a lot more, instead of just rendering png/jpg graphics. This way, the accessibility tools could be built as browser addons, rather than making every single tool that offers any kind of visualizations re-implement accessibility over and over again.
