GetVolumeAccessGroupEfficiency
You can use the GetVolumeAccessGroupEfficiency
method to get efficiency information about a volume access group. Only the volume access group you provide as the parameter in this API method is used to compute the capacity.
Parameter
This method has the following input parameter:
Name | Description | Type | Default value | Required |
---|---|---|---|---|
volumeAccessGroupID |
Specifies the volume access group for which capacity is computed. |
integer |
None |
Yes |
Return value
This method has the following return value:
Name |
Description |
Type |
compression |
The amount of space saved by data compression for all volumes in the volume access group. Stated as a ratio where a value of 1 means data has been stored with no compression. |
float |
deduplication |
The amount of space saved by not duplicating data for all volumes in the volume access group. Stated as a ratio. |
float |
thinProvisioning |
The ratio of space used to the amount of space allocated for storing data. Stated as a ratio. |
float |
timestamp |
The last time efficiency data was collected after garbage collection. |
ISO 8601 data string |
missingVolumes |
The volumes that could not be queried for efficiency data. Missing volumes can be caused by a recent garbage collection, temporary network loss or restarted services since the garbage collection cycle. |
integer array |
