Answer

Capacity in ONTAP System Manager Dashboard shows sizes of USED and AVAILABLE.

REST API and CLI to obtain these values are:

  • REST API for USED

[<CLUSTER>/api/storage/cluster?fields=*]

  • CLI for USED

::*> storage aggregate show-efficiency -aggregate <AGGREGATE> -fields aggregate,total-logical-used,total-physical-used,aggr-logical-used,aggr-physical-used,total-storage-efficiency-ratio

Note: Advanced privilege is required.

  • REST API for AVAILABLE

[<CLUSTER>/api/storage/aggregates?fields=space,space.block_storage.inactive_user_data,*]

  • CLI for AVAILABLE

::> df -A

 

Example:

Results of REST API and CLI corresponding to the above screenshot(USED is 7.32 MB, AVAILABLE is 28.32 GB).

  • REST API for USED

[cluster2/api/storage/cluster?fields=*]

<snip>
{
"efficiency": {
    "savings": 0,
    "ratio": 1,
    "logical_used": 7671808
},
</snip>

Logical_used: 7671808 == 7671808/1024/1024 == 7.32 MB

  • CLI for USED

::*> storage aggregate show-efficiency -aggregate aggr1_cluster2_01 -fields aggregate,total-logical-used,total-physical-used,aggr-logical-used,aggr-physical-used,total-storage-efficiency-ratio

aggregate                 total-logical-used     total-physical-used     total-storage-efficiency-ratio     aggr-logical-used     aggr-physical-used
-----------------             ------------------             -------------------             ------------------------------             -----------------             ------------------
aggr1_cluster2_01     7.32MB                     13.83MB                     1.00:1                                         13.83MB                   13.83MB


total-logical-used = 7.32 MB

  • REST API for AVAILABLE

[cluster2/api/storage/aggregates?fields=space,space.block_storage.inactive_user_data,*]

Only Data Aggregates (No Root Aggregate):

<snip>
"space": {
"footprint": 25886720,
"block_storage": {
    "size": 30439669760,
    "available": 30404370432,
    "used": 35299328,
    "full_threshold_percent": 98
},
</snip>

Available Space: 30404370432/1024/1024/1024 == 28.32 GB

  • CLI for AVAILABLE

::> df -A
Aggregate                           kbytes               used          avail         capacity
aggr1_cluster2_01             29726240     34332       29691908       0%
aggr1_cluster2_01/.snapshot  0                  0              0                   0%

Available Space: 29691908 == 29691908/1024/1024 == 28.32 GB
