Instructions

要使用 REST 查看每个存储池的当前 IOPS 和 Kb/s 统计信息，请使用以下 API：

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

它返回存储池统计信息，以及每种流量类型（主读取、写入、重新平衡、重建等）的以下其他“*BWC”条目：

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

要获取每种流量的 IOPS 数，请将“numOccured”除以“numSeconds”，要查看 Kb/s 将“totalWeightInKb”除以“numSeconds”，请在以下示例中执行以下作：

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

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

Additional Information

如果您主要使用 CIFS/NFS 来写入备份，则应使用 scli --query_storage_pool 命令生成以下输出，允许我们查看每个存储池的流量：
REST API 中没有此类计数器，必须计算这些值。
