machine with multiple disks

[rickysarraf]

Is the extension supported with multiple disks ? I don't think so because then there'd be multiple HDD indicators.

Can you make the block device, that you read from /proc/diskstats, to be configurable ?
Also, can you add support for reporting for multiple block devices ?

There are many use cases.

1. BTRFS volume with multiple block devices
2. LVM with multiple block devices
3. RAID with multiple block devices.
4. Above 3 stacked together.
5. Ram block devices
6. Many more use cases.

So, easiest would be if you could add some UI to let the user feed in the block device(s).

I don't know javascript, but as I understand this code, you are assuming that the device that has its 2nd field as 0, is the parent block device ?

please try latest version in github,
extensions.gnome.org haven't approved last changes

I think it is working now. But with reads and writes not distinguished, it is not very obvious.

Please have a look at https://extensions.gnome.org/extension/120/system-monitor/
They have reads and writes done very well.
