REST风格的API和System Manager未返回卷统计信息

适用场景

问题描述

• REST命令：GET for /storage/volumes/REST <instance-UUID> 不会返回任何卷统计信息。

示例：

root@x.x.x.x:/home # curl -u sde:supersecretpassword --insecure https://10.x.x.94/api/storage/volumes/ae908815-f3fa-xxxx-bcb5-d039ea2315e3

 "metric": {
  "timestamp": "2022-03-22T17:27:30Z",
  "duration": "PT15S",
  "status": "ok",
  "latency": {
   "other": 0,
   "total": 0,
   "read": 0,
   "write": 0
   },
  "iops": {
   "read": 0,
   "write": 0,
   "other": 0,
   "total": 0
   },
  "throughput": {
   "read": 0,
   "write": 0,
   "other": 0,
   "total": 0
   }
  },
 

• 但是、可以从命令行界面提取统计信息

::> qos statistics volume latency show -volume vol_xxx
