[pve-devel] Extra Node Summary Information

I appreciate your interest in PVE and the open source development.

To point it out first 
http://pve.proxmox.com/wiki/Developer_Documentation may help you somewhat.
While it may look like a lot at the beginning after you initial setup a 
machine (maybe an VM with nested Proxmox) building the packages and 
changing something becomes easier, if your already have basic 
development skills it helps you much.

As you can read also in the last paragraph we need an contributor 
agreement (it ensures that you hold the copyright of your work when you 
contribute to the project, but we may use it for the project, legal stuff).
Contributing (especially to the first) to Open-source projects may have, 
unfortunately, some initial troubles and a learning curve for the 
standard tools (like git), don't let you scare from that.

To be direct: The RRD stuff you proposed probably won't get into the PVE 
upstream code.
Although it's for sure a nice and cool feature there are already tools 
out there which are much better for the job. PVE is more a cluster 
framework, monitoring should be done by monitoring frameworks.

But we recently applied an new status plugin, so you could use 
https://influxdb.com/ or also Graphite to gather all the information, 
see nice graphs and timelines.

But if you say, hey I do it my way, still post your changes (as a 
patch), but don't be disappointed if they get rejected. :)

Note, take this answer as an personal from me, not Proxmox or affiliates.

Best Regards,
