Red Hat Summit5.82. nova hypervisor-stats
usage: nova hypervisor-stats
Get hypervisor statistics over all compute nodes.
Warning
When using Red Hat Ceph as a back end for ephemeral storage, the Compute service does not calculate the amount of available storage correctly. Specifically, Compute simply adds up the amount of available storage without factoring in replication. This results in grossly overstated available storage, which in turn could cause unexpected storage oversubscription.
To determine the correct ephemeral storage capacity, query the Ceph service directly instead. For more information, see BZ#1332165.
