Disk graph

[vimalaguti]

Describe the feature request

Hi, I'm usually interested in the IO disk graph but this information is only available in programs like nmon and the windows 10 task manger.
I would really appreciate a plugin showing MiB read/written and active time, maybe an history graph too - for each drive.

@vimalaguti yep, graphing stuff like temps and disk have been something I want to get to --- definitely going to try to add these at some point.

Just want to bump this and say that this would be a very nice feature. The simplest change that could be made to improve this would be to add a total write/read section to the disks widget, as already exists in the process one. I would like to determine how much of FF's seeming 1GB / hour being written is to my actual disk vs. .cache (a ramdisk for me).

If I could read the code I would try to implement it myself since it really shouldn't be that hard, since the real-time data already is available. But I am really lost in this project, sorry

Yeah, this is something I still want to do! Just been really busy with school/work for a while now (especially the last few weeks), but I have a few weeks off so I can hopefully make significant progress in the coming weeks. Some of the stuff I'm working on now should hopefully make adding future features like this much easier.

But I am really lost in this project, sorry

Haha, yeah, hopefully what I'm working on right now improves that slightly...

I saw the notes in the refactor issue about improving code reuse and storing widget state locally in each widget. I also have a tough time looking at big rust projects in general, I made a few edits to alacritty but that was a lot of trial and error. I might take another look at it though if I have time, I'm starting school here this week as well.

Vote up for I/O graphs ! It'd be awesome to have an I/O graph for disk read and write (similar to the existing Network graph).
