We can have additional information about the read/write characters for the process as well.

@ishleenk17 Do you have any example of how these new metrics would look like? I think we will need to add them into SemConv first

Is this what you're looking for (process.disk.operations)? #14566

This metric captures read/write operation counts.

If this isn't what you are referring to, would you mind clarifying a bit more please?

[rogercoll]

I think @ishleenk17 is referring to the amount of read/write characters :

# cat /proc/3828/io
rchar: 323934931
wchar: 323929600
syscr: 632687
syscw: 632675
read_bytes: 0
write_bytes: 323932160
cancelled_write_bytes: 0

@ishleenk17 could you confirm?
