[REQUEST] Include non-mountpoint blockdevices in IO stats

[KJ7LNW]

Is your feature request related to a problem? Please describe.

I just tried btop and love it, but on our hypervisors where we need IO stats I can only see mountpoint IO stats. All of our VMs are LVM-backed, so somehow we need to see IO stats for non-mountpoint disks.

Describe the solution you'd like

• Include all disks in the disk pane.
• Allow them to be filtered in the same way that btop.conf/disk_filter does.
• Allow filtering by pressing / like in procs.
• Complete these related issues:

  • 409

  • 408

Describe alternatives you've considered Alternatives? I could use dstat or dool instead, but btop is awesome ;)

This is related to (but not a duplicate of) #108.

The implementation suggestions are slightly different: This enhancement suggests re-using the existing disk pane, the other says add a new pane for block device IO.

I'm not attached to either implementation, I just want to see per-blockdev stats with the ability to filter, scroll, and sort by:

• Read IOPS
• Write IOPS
• Write Bandwidth (MB/s, GB/s, etc.)
• Write Bandwidth (MB/s, GB/s, etc.)

Maybe these two issues should be merged? I'll leave it up to whatever is best/easiest for the developer(s) to implement.
