Note that Cassandra usage is already tracked in graphite. We don't have them in a consolidated dashboard. @elukey has already done significant work to align different Cassandra dashboards (see T193017). We can probably build on that.
We also have a bunch of postgresql metrics exported to prometheus (see P7144 for an example). I'm not sure what is useful here. It does not look like we are tracking DB sizes yet, but it is probably not too hard to add. Upstream documentation: https://github.com/wrouesnel/postgres_exporter.

Given that this task was opened when the infra was completely different, I am bluntly closing this task. I am happy to re-open if/when we believe there are reasons to do anything more than rely in the default disk usage monitors we already have for all hosts
