Name Description Schema
snapshot_savi
ngs
optional
Ratio of the amount of space that would have been used by
snapshots if space efficiency was not applied to logical
space used solely by snapshots of vVols used by virtual
machine. For example, a vVol is provisioned as 1 GB and it
has two snapshots. Each snapshot has 200 MB of data.
Snapshot savings will be (1 GB + 1 GB) / (0.2 GB + 0.2 GB) or
5:1. The snapshot_savings value will be 5 in this case.
number (float)
thin_savings
optional
Ratio of all the vVol provisioned to data they contain. This
is the ratio of logical_provisioned to logical_used. For
example, a VM has two 2 GB vVol’s and have written 500
MB of data to them. The thin savings would be (2 * 2GB) / (2
* 0.5 GB) or 4:1, so the thin_savings value would be 4.0.
number (float)
timestamp
optional
End of sample period. string (date-time)
unique_physic
al_used
optional
Amount of physical space virtual machine used after
compression and deduplication. This is the space to be
freed up if a virtual machine is removed.
Minimum value : 0
Maximum value : 9223372036854775807
integer (int64)
vm_id
optional
Unique identifier representing a specific virtual machine. string
base_space_metrics_by_vm_rollup
Summary of VM level space metric data for one hour or one day period beginning with timestamp,
including the maximum and final values for that period.
Name Description Schema
last_logical_pr
ovisioned
optional
Last logical provisioned space during the period.
Minimum value : 0
Maximum value : 9223372036854775807
integer (int64)
last_logical_us
ed
optional
Last logical used space during the period.
Minimum value : 0
Maximum value : 9223372036854775807
integer (int64)
last_snap_clon
e_logical_used
optional
Last snap and clone logical used space during the period.
