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?
