Grafana dashboard: Ceph - Pools
Description: Ceph Pools dashboard.

Ceph Pool overview, built for ceph-mgr's built-in prometheus exporter (available since 13.2 Mimic) with the following features:
- Multi-cluster support (cluster is selected via $job)
- Pool selection by name

Per-pool:
- Storage Used/Available (stacked)
- Usage %
- Objects in Pool
- IOPS
- Throughput
