Per-disk throughput should filter out loop* and ram* entries #21034

Page: Overview > Metrics and history > View per-disk throughput

The dialog that opens after clicking the link overflows on top of the screen, and displays many different devices that display zeroes. Since the Disks widget (?) seems to target physical drives, it would be nice if these virtual devices were filtered out.

Additionally, instead of clipping over the top, it should be scrollable, this way the users have no way of checking whether there is a header row, or whether there's some important drive above the virtual ones.

What are these ram0 devices? Interesting that podman shows up, I guess that's with the overlayfs backend? (not btrfs?)

The system is running on Raspberry Pi, it seems the image is configured to use https://www.kernel.org/doc/html/latest/admin-guide/blockdev/ramdisk.html.
