# 监控导出映像任务


使用 VM Import/Export 启动映像导出任务后，您可以监控导出操作。

------
#### [ Amazon CLI ]

**监控导出映像任务**  
使用以下 [describe-export-image-tasks](https://docs.amazonaws.cn/cli/latest/reference/ec2/describe-export-image-tasks.html) 命令。

```
aws ec2 describe-export-image-tasks \
    --export-image-task-ids export-ami-1234567890abcdef0
```

下面是示例输出。所示状态为 `active`，表明导出任务正在进行。当状态为 `completed` 时，表示映像可供使用。

```
{
  "ExportImageTasks": [
      {
          "Description": "Jul 15 16:31 My image export",
          "ExportImageTaskId": "export-ami-1234567890abcdef0",
          "Progress": "21",
          "S3ExportLocation": {
              "S3Bucket": "amzn-s3-demo-export-bucket",
              "S3Prefix": "exports/"
          },
          "Status": "active",
          "StatusMessage": "updating"
      }
  ]
}
```

**监控所有导出映像任务**  
使用以下 [describe-export-image-tasks](https://docs.amazonaws.cn/cli/latest/reference/ec2/describe-export-image-tasks.html) 命令。

```
aws ec2 describe-export-image-tasks \
  --query "ExportImageTasks[*].{\
    Description:Description,\
    ExportImageTaskId:ExportImageTaskId,\
    ImageId:ImageId,\
    Status:Status,\
    Progress:Progress,\
    S3Bucket:S3ExportLocation.S3Bucket}" \
  --output table
```

下面是示例输出。

```

|  Jul 15 16:31 My image export|  export-ami-1234567890abcdef1 |  ami-ab34567890abcdef0 |  None     |  amzn-s3-demo-export-bucket  |  completed  |
+------------------------------+-------------------------------+------------------------+-----------+------------------------------+-------------+
```

#### [ PowerShell ]

**监控导出映像任务**  
按如下方式使用 [Get-EC2ExportImageTask](https://docs.amazonaws.cn/powershell/latest/reference/items/Get-EC2ExportImageTask.html) cmdlet。

```
Get-EC2ExportImageTask `
   -ExportImageTaskId export-ami-1234567890abcdef0 |
      Format-List *, 
         @{Name='S3ExportLocation';Expression={$_.S3ExportLocation | Format-List | Out-String}}
```

下面是示例输出。所示状态为 `active`，表明导出任务正在进行。当状态为 `completed` 时，表示映像可供使用。

```
Description       : Jul 15 16:35 My image export
ExportImageTaskId : export-ami-1234567890abcdef0
ImageId           : ami-ab34567890abcdeff
Progress          : 80
S3ExportLocation  : Amazon.EC2.Model.ExportTaskS3Location
Status            : active
StatusMessage     : converting
Tags              : {}
S3ExportLocation  : 
                    S3Bucket : amzn-s3-demo-export-bucket
                    S3Prefix : exports/
```

**监控所有导出映像任务**  
按如下方式使用 [Get-EC2ExportImageTask](https://docs.amazonaws.cn/powershell/latest/reference/items/Get-EC2ExportImageTask.html) cmdlet。

```
Get-EC2ExportImageTask | 
   Format-Table Description, ExportImageTaskId, ImageId, Status, Progress,  
   @{Name='S3Bucket';Expression={$_.S3ExportLocation.S3Bucket}}
```

下面是示例输出。

```
Description                  ExportImageTaskId            ImageId               Status    Progress S3Bucket
