It is not top/htop replacement because of historical snapshots which can help you to find problems back in time

At what resolution does it store the sampled metrics? How easily are they pruned/aged out?

Seems like a bit of a combination of "sar" (sysstat) and pt-stalk - a percona-toolkit tool originally designed for MySQL DBAs that would let you wait until a certain system or MySQL condition happened (high cpu, disk I/O, connections maxed out, etc) and then start collecting lots of system and MySQL stats. Rather than having to do them all the time.

Plus a nice TUI :)

What's the value add when comparing this with `atop`? atop has a history recording feature that I have relied on in past.

- atop does not have mounts status

- interface a bit more intuitive: - you see full day on top chart, see spikes on it and scroll into the moment to check it in details

- alerts/notifications

- does not need root
