Instructions

若要使用 REST 檢視每個儲存集區的目前 IOPS 和 Kb/s 統計資料，請使用下列 API：

 /api/instances/StoragePool::xxxxxxxxxxx/relationships/Statistics

它會傳回儲存集區統計資料，以及每種流量類型 （主要讀取、寫入、重新平衡、重建等） 的下列「*Bwc」項目：

(...)
    "primaryWriteBwc": {
        "numOccured": 219,
        "numSeconds": 5,
        "totalWeightInKb": 111884
    },
(...)

若要取得每種流量的 IOPS 數除以「numSeconds」，請參閱 Kb/s 將「totalWeightInKb」除以「numSeconds」- 在此範例中：

 
 
    "primaryWriteBwc": {
        "numOccured": 219,
        "numSeconds": 5,
        "totalWeightInKb": 111884
    },

===================
<<< Calcuation >>>
219/5 = ~43 IOPS
111884/5 = ~ 22376 Kb/s

Additional Information

可使用 scli --query_storage_pool 命令會產生下列輸出，讓我們能夠查看每個儲存集區的
流量：REST API 中沒有此類計數器，必須計算這些值。

(...) 
        Primary-reads                            5365 IOPS 21.0 MB (21461 KB) per-second
        Primary-writes                           41 IOPS 20.9 MB (21425 KB) per-second
        Secondary-reads                          0 IOPS 0 Bytes per-second
        Secondary-writes                         40 IOPS 20.4 MB (20870 KB) per-second
