I think that you are confusing real-time metrics, streamed with very high precision (below 1s) and metrics that are simply polled every N time (most use-cases).
real-time, high precision metrics aren't necessary. when you say that you don't need metrics and then say that you can poll metrics periodically, you are contradicting yourself.
I'm not contradicting myself. I'm saying you just poll for storage, you don't store the results. My entire thesis is that those metrics aren't worth storing.
crossing fingers that the process that is polling the storage doesn't crash in the future, so you won't be left in the dark, as there is no metric stored, so you will never know when things will go down the drain.
