Not the same kind of monitor tool exactly, but, I keep finding dstat hard to leave behind. Because I can see the past there! So many of these monitors have one or two or three over time graphs, but most of the information is ephemeral, only shows right now. But I really want to see network use, disk use, paging, context switching/interrupts over time!

There is also Below. Which has a much more htop/btop like interface than dstat. Below records system info over time, and allows time travel! However, it's not as convenient as dstat, not at a glance, as one has to to scrub through time. But it is pretty impressive system monitoring, great for what it is! It's per-process pressure metrics are also utterly unbeatable. The way it rolls up cgroups is also stellar. https://github.com/facebookincubator/below
