搭配使用 DescribeFlowLogs 與 CLI

下列程式碼範例示範如何使用 DescribeFlowLogs。

CLI

AWS CLI

範例 1：描述您的所有流程日誌

下列describe-flow-logs範例會顯示所有流程日誌的詳細資訊。

aws ec2 describe-flow-logs

輸出：

{
    "FlowLogs": [
        {
            "CreationTime": "2018-02-21T13:22:12.644Z",
            "DeliverLogsPermissionArn": "arn:aws:iam::123456789012:role/flow-logs-role",
            "DeliverLogsStatus": "SUCCESS",
            "FlowLogId": "fl-aabbccdd112233445",
            "MaxAggregationInterval": 600,
            "FlowLogStatus": "ACTIVE",
            "LogGroupName": "FlowLogGroup",
            "ResourceId": "subnet-12345678901234567",
            "TrafficType": "ALL",
            "LogDestinationType": "cloud-watch-logs",
            "LogFormat": "${version} ${account-id} ${interface-id} ${srcaddr} ${dstaddr} ${srcport} ${dstport} ${protocol} ${packets} ${bytes} ${start} ${end} ${action} ${log-status}"
        },
        {
            "CreationTime": "2020-02-04T15:22:29.986Z",
            "DeliverLogsStatus": "SUCCESS",
            "FlowLogId": "fl-01234567890123456",
            "MaxAggregationInterval": 60,
            "FlowLogStatus": "ACTIVE",
            "ResourceId": "vpc-00112233445566778",
            "TrafficType": "ACCEPT",
            "LogDestinationType": "s3",
            "LogDestination": "arn:aws:s3:::my-flow-log-bucket/custom",
            "LogFormat": "${version} ${vpc-id} ${subnet-id} ${instance-id} ${interface-id} ${account-id} ${type} ${srcaddr} ${dstaddr} ${srcport} ${dstport} ${pkt-srcaddr} ${pkt-dstaddr} ${protocol} ${bytes} ${packets} ${start} ${end} ${action} ${tcp-flags} ${log-status}"
        }
    ]
}

範例 2：描述流程日誌的子集

下列describe-flow-logs範例使用篩選條件來僅顯示 Amazon CloudWatch Logs 中指定日誌群組中流程日誌的詳細資訊。

aws ec2 describe-flow-logs \
    --filter "Name=log-group-name,Values=MyFlowLogs"

• 如需 API 詳細資訊，請參閱 AWS CLI 命令參考中的 DescribeFlowLogs。

PowerShell

Tools for PowerShell

範例 1：此範例描述一或多個具有日誌目的地類型 's3' 的流量日誌

Get-EC2FlowLog -Filter @{Name="log-destination-type";Values="s3"}

輸出：

CreationTime             : 2/25/2019 9:07:36 PM
DeliverLogsErrorMessage  :
DeliverLogsPermissionArn :
DeliverLogsStatus        : SUCCESS
FlowLogId                : fl-01b2e3d45f67f8901
FlowLogStatus            : ACTIVE
LogDestination           : arn:aws:s3:::my-bucket-dd-tata
LogDestinationType       : s3
LogGroupName             :
ResourceId               : eni-01d2dda3456b7e890
TrafficType              : ALL
