I'm very excited to see this project. I've been mentioning around the office for weeks that the community needs a better idea of how K8s is actually being used.

I'd like to help expand the project to collect more useful information about installations. Here's a dump of the things I've been wondering about that we could collect. I'd be willing to add any of these or help in the collection & anonymization of other datapoints.

Context (these would likely need to be provided in plain text at launch time, so wouldn't want to ask a lot)

Phase of cluster (e.g. prototype, development, staging, production)
Installed in private datacenter or (specific) public cloud?

Careful on this last one. It's probably OK to send which
--cloud-provider, but that flag will eventually EOL and I'd rather not
lose useful info.

Cluster setup

Master node count

Should show in in th einfo we have today, though we don't flag nodes
as masters, so ..

Etcd node count
Service node count
Node volatility, how quickly are nodes added or removed from the cluster?
Node consistency [specifically I wonder if master/etcd nodes are sized the same as other nodes]
Are Etcd nodes also worker nodes (cf self hosting)

Networking
-- Block size of Pod & Service networks
-- Is an overlay network being used
-- Is policy enabled
-- Is CNI being used
-- What, if any, SDN is in use

Careful not to collect anything potentially identifying.

Disk settings

How big/fast are the disks used to host nodes?
What are the log rates of the kubernetes components?

Currently we only collect info that is available through the APi, so
you would have to extend API to collect these or else start collecting
from some metrics.
