> You can poll storage periodically though, you don't need to keep a constant metrics stream of where it's at. Also you can set up each machine to alert when it's own storage fills up.

Unless you want to be able to have trends over time, either for capacity planning (needing to order more storage in case of bare metal, or planning costs ahead) or to correlate with other things (storage consumption is growing twice as fast since deployment X, did we change something there?).

You don't need to have 1s granularity metrics on storage consumption, but having none is just stupid levels of fake "optimisation" that will cost you more in the long run.
