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.
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 |
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 |
Requests for this method are similar to the following example:
{ "method": "GetVolumeAccessGroupEfficiency", "params": { "volumeAccessGroupID": 1 }, "id": 1 }
This method returns a response similar to the following example:
{ "id": 1, "result": { "compression": 2.006012925331075, "deduplication": 1, "missingVolumes": [], "thinProvisioning": 1.009861932938856, "timestamp": "2014-03-10T17:05:27Z" } }
