块存储事件通知

事件列表

块存储可以设置的事件通知包括：

• 系统事件

• 挂载或者卸载数据盘

• 保留云盘

• 欠费释放

系统事件

块存储只有异常类事件，不存在维护类系统事件。在事件发生和结束时，均可以发出事件通知。不同系统事件对应的事件通知名称，请参见附录：块存储系统事件对应的事件通知名称。

以块存储性能受到严重影响（Stalled）的系统事件为例。事件通知的JSON格式如下所示：

• 首次发布块存储系统事件时，事件具有executeStartTime属性。

  {
    "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"
    }
  }

• 当块存储系统事件结束时，您会收到相应通知。相较于首次收到的事件通知，增加了一条executeFinishTime属性。

  {
    "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"        
    }
  }

挂载或者卸载数据盘

当数据盘完成挂载或者卸载时，云服务器ECS会发送云盘操作成功或失败的事件。更多信息，请参见挂载数据盘和卸载数据盘。

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"
  }
}

保留云盘

通过关闭随实例释放，释放ECS实例时，挂载的云盘（包括系统盘和数据盘）都会被转换成按量付费数据盘而保留下来。更多信息，请参见释放云盘。

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"
    }
}

欠费释放

{
    "id": "2256A988-0B26-4E2B-820A-8A********E5",
    "product": "ECS",
    "resourceId": "acs:ecs:cn-hangzhou:169070********30:disk/d-t4ndyqve********n4ds",
    "level": "CRITICAL",
    "instanceName": "disk-event-subscription",
    "name": "Disk:OverduePaymentRelease",
    "userId": "169070********30",
    "eventTime": "20190409T121826.922+0800",
    "regionId": "cn-hangzhou",
    "content": {
    "instanceId" : "i-bp1792********an2ukf",
    "diskId" : "d-t4ndyqve********n4ds"
    }
}
