There doesn't seem to be anything to monitor Storage Pools and Virtual Disks. Ideally a new widget / panel could be created which might sit under the typical Disk Volumes one, to show storage pool total size, unallocated space, health, and the same for Virtual Disks.
We are now making use of Storage Spaces and it would be good not to have to produce our own custom monitoring for this.
Does anybody else already monitor these?
