On my Mac, sometimes one of the external Time Machine drives just starts making noise non-stop. I have to dismount and power-cycle it. But I wonder what process is writing to it or reading from it. The macOS Activity Monitor doesn't have it. And I don't think the Unix 'top' command has it either. Not that I could find, anyway.

Does _any_ other OS have this feature, $ MONITOR PROC/TOPDIO

I ask here in the hopes of not having to explain MONITOR PROC/TOPDIO to people in other forums.

TIA.

The newer Windows task manager can, as can the related resource monitor,
available from the performance tab.

The linux utility HTOP can view I/O by process. There is probably a
version that can build on the mac.

htop was originally developed by Hisham Muhammad. Nowadays it is
maintained by the community at <htop@groups.io>

Try https://htop.dev/

If Activity Monitor app (network, disk) and top don't get you where you
want here, then iostat and fs_usage might be useful analogs. See man
for details.
Other potential add-on options for monitoring macOS and some other
platforms are Glances (https://github.com/nicolargo/glances) and htop.
Xcode Instruments is built atop DTrace framework, if you wanted to go
that way. With Xcode installed, launch Instruments and select Activity
Monitor, or such.

On a related note, I wouldn't mind seeing dtrace functionality for VMS
(or even something as simple as strace).

The whole management and troubleshooting area is lacking, yes.

OPCOM, ANALYZE /AUDIT, and ACCOUNTING were all outdated by Y2K, and
have only sunk further behind.

Some of the DECclassic monitoring and troubleshooting tools were
cancelled, some were sold off, some are still available as add-ons from
VSI, some are rebuilt as SDA extensions, RMI was added, etc.

The scale of work VSI has ahead is unfathomable, and the trade-offs myriad.
