Support for HDD IOPS / bytes

[easel]

Describe the new feature you'd like I'd like to see the amount of hdd bytes read/written and read/write ops for each disk.

Additional context IOTOP displays the information I'm asking for, but I don't where's it's read from and it requires sudo so I'm not fully optimistic it's just a /proc read away. That said, there does seem to be some interesting information available under /sys/block/

[corecoding]

Is there a formula that you know of to calculate IOPS?

[dorsi]

maybe iotop -ob | egrep "Current DISK READ|Current DISK WRITE"

This command seems to work :+1:

Current DISK READ:    1355.82 K/s | Current DISK WRITE:       0.00 B/s
Current DISK READ:     658.96 K/s | Current DISK WRITE:       0.00 B/s
Current DISK READ:     466.95 K/s | Current DISK WRITE:       0.00 B/s
Current DISK READ:      15.59 K/s | Current DISK WRITE:     311.79 K/s

It could be very interesting to implement it.
