Storage is the only thing missing as far as being able to see an exact cost per DO would be useful to add on for that reason. But

durableObjectsPeriodicGroups

has: - activeTime (in microseconds) - storageDeletes - storageReadUnits - storageWriteUnits - inboundWebsocketMsgCount (im assuming this is only the new api that isnt ready yet) And

durableObjectsInvocationsAdaptiveGroups

has: - requests ( Ps can we also get fetchCount, and alarmCount on durableObjectsPeriodicGroups 😛 or at the very least the request sum)
