Elastic Compute Service：Block Storage事件通知

事件列表

Block Storage可以設定的事件通知包括：

• 系統事件

• 掛載或者卸載資料盤

• 保留雲端硬碟

• 欠費釋放

系統事件

Block Storage只有異常類事件，不存在維護類系統事件。在事件發生和結束時，均可以發出事件通知。不同系統事件對應的事件通知名稱，請參見附錄：Block Storage系統事件對應的事件通知名稱。

以Block Storage效能受到嚴重影響（Stalled）的系統事件為例。事件通知的JSON格式如下所示：

• 首次發布Block Storage系統事件時，事件具有executeStartTime屬性。

  {
    "id": "2256A988-0B26-4E2B-820A-8A********E5",
    "product": "ECS",
    "resourceId": "acs:ecs:cn-hangzhou:169070********30:disk/d-t4ndyqve********n4ds",
    "level": "CRITICAL",
    "name": "Disk:Stalled:Executing",
    "userId": "169070********30",
    "eventTime": "20190410T080101.922+0800",
    "regionId": "cn-hangzhou",
    "content": {
      "eventId": "e-t4navn7********6x5no",
      "diskId": "d-t4ndyqve********n4ds",
      "device": "/dev/xvdb",
      "eventType": "Stalled",
      "executeStartTime": "2019-04-10T01:01:01Z",
      "ecsInstanceId": "i-bp1ecr********5go2go",
      "ecsInstanceName": "ecs-instance-name"
    }
  }

• 當Block Storage系統事件結束時，您會收到相應通知。相較於首次收到的事件通知，增加了一條executeFinishTime屬性。

  {
    "id": "2256A988-0B26-4E2B-820A-8A********E5",
    "product": "ECS",
    "resourceId": "acs:ecs:cn-hangzhou:169070********30:disk/d-t4ndyqve********n4ds",
    "level": "CRITICAL",
    "name": "Disk:Stalled:Executing",
    "userId": "169070********30",
    "eventTime": "20190410T080301.922+0800",
    "regionId": "cn-hangzhou",
    "content": {
      "eventId": "e-t4navn7********6x5no",   
      "diskId": "d-t4ndyqve********n4ds",    
      "device": "/dev/xvdb",                 
      "eventType": "Stalled",                
      "executeStartTime": "2019-04-10T01:01:01Z",   
      "executeFinishTime": "2019-04-10T01:03:01Z",  
      "ecsInstanceId": "i-bp1ecr********5go2go",    
      "ecsInstanceName": "ecs-instance-name"        
    }
  }

掛載或者卸載資料盤

當資料盤完成掛載或者卸載時，Elastic Compute Service會發送雲端硬碟完成操作成功或失敗的事件。更多資訊，請參見掛載資料盤和卸載資料盤。

事件通知的JSON格式如下所示：

{
  "id": "2256A988-0B26-4E2B-820A-8A********E5",
  "product": "ECS",
  "resourceId": "acs:ecs:cn-hangzhou:169070********30:disk/d-t4ndyqve********n4ds",
  "level": "INFO",
  "name": "Disk:DiskOperationCompleted",
  "userId": "169070********30",
  "eventTime": "20190409T121826.922+0800",
  "regionId": "cn-hangzhou",
  "content": {
      "diskId" : "d-t4ndyqve********n4ds",
      "operation" : "AttachDisk",
      "result" : "accomplished",
      "instanceId" : "i-t4ndpdf***********dsa",
      "diskType" : "data"
  }
}

保留雲端硬碟

通過關閉隨執行個體釋放，釋放ECS執行個體時，掛載的雲端硬碟（包括系統硬碟和資料盤）都會被轉換成隨用隨付資料盤而保留下來。更多資訊，請參見釋放雲端硬碟。

事件通知的JSON格式如下所示：

{
    "id": "2256A988-0B26-4E2B-820A-8A********E5",
    "product": "ECS",
    "resourceId": "acs:ecs:cn-hangzhou:169070********30:disk/d-t4ndyqve********n4ds",
    "level": "INFO",
    "instanceName": "disk-event-subscription",
    "name": "Disk:ConvertToPostpaidCompleted",
    "userId": "169070********30",
    "eventTime": "20190409T121826.922+0800",
    "regionId": "cn-hangzhou",
    "content": {
    "diskId" : "d-t4ndyqve********n4ds",
    "result" : "accomplished"
    }
}

欠費釋放

{
    "id": "2256A988-0B26-4E2B-820A-8A********E5",
    "product": "ECS",
    "resourceId": "acs:ecs:cn-hangzhou:169070********30:disk/d-t4ndyqve********n4ds",
