Name logical_used optional Description Schema Total amount of data in bytes written to all member volumes in a volume group. Minimum value : 0 integer (int64) Maximum value : 9223372036854775807 repeat_count optional Number of times the metrics are repeated. Minimum value : 0 Maximum value : 2147483647 integer (int32) response_defi nition Response definition for the entity. required string snap_clone_lo gical_used optional Total amount of data in bytes host has written to all volumes in the volume group without any deduplication, compression or sharing. This metric includes used snaps integer (int64) and clones in the volume group. Minimum value : 0 Maximum value : 9223372036854775807 Ratio of the amount of space that would have been used by snapshots in the volume group if space efficiency was not snapshot_savi ngs optional applied to logical space used solely by snapshots. For example, two volumes are provisioned as 1 GB and has two snapshots. Each snapshot has 200 MB of each data. number (float) Snapshot savings will be (1 GB * 2 + 1 GB * 2) / (0.2 GB * 2 + 0.2 GB * 2) or 5:1. The snapshot_savings value will be 5 in this case. thin_savings optional Ratio of all the volumes provisioned to data being written to them. For example, a volume group has two 2 GB volumes and have written 500 MB of data to them. The thin number (float) savings would be (2 * 2 GB) / (2 * 0.5 GB) or 4:1, so the thin_savings value would be 4.0. timestamp optional End of sample period. string (date-time) vg_id optional Unique identifier representing a volume group. string space_metrics_by_vg_family Space metrics for a volume group family collected at a five minute interval.
