but you don't actually need the metrics themselves but only the computed
moving avg result and such of them? Because if that's the case we could just
keep the last X values we require for the moving window cached locally in
pvestatd and use those to broadcast the calculated ones use for DRS once or
twice every minute or so via the per-node kv status in the pvestatd?
Could mean less data an no new RRD format/paths (iow. no touching of
pve-cluster at all). What do you think?
