[pve-devel] Qemu Guest IOPS Graphing

[Darryl Dixon]

Hi,

I have been working through the logistics of providing a patch for this
functionality with data stored in a separate file, as requested here:
http://pve.proxmox.com/pipermail/pve-devel/2015-November/018096.html

However, the real difficulty lies not in getting the data stored into a
separate file, but rather in reading the data back out and incorporating it
into the UI without either duplicating a lot of code throughout the stack
to create a parallel 'pipeline' through the layers of code & services back
up to the UI, or invasively rewriting a significant amount of existing
functions/code around how the data is represented up through the stack to
allow two different data sources to be sensibly merged together into one.
Before embarking on one or the other scenario, I thought I would run this
past the list to get a feel for which approach is preferred, or whether
someone with a deep understanding of the existing code could offer a 'quick
win' that solves this in a way that I have not yet contemplated.

regards,
