FlowLogProps

class aws_cdk.aws_ec2.FlowLogProps(*, destination=None, log_format=None, max_aggregation_interval=None, traffic_type=None, resource_type, flow_log_name=None)

Bases: FlowLogOptions

Properties of a VPC Flow Log.

Parameters:

  • destination (Optional[FlowLogDestination]) – Specifies the type of destination to which the flow log data is to be published. Flow log data can be published to CloudWatch Logs or Amazon S3 Default: FlowLogDestinationType.toCloudWatchLogs()

  • log_format (Optional[Sequence[LogFormat]]) – The fields to include in the flow log record, in the order in which they should appear. If multiple fields are specified, they will be separated by spaces. For full control over the literal log format string, pass a single field constructed with LogFormat.custom(). See https://docs.aws.amazon.com/vpc/latest/userguide/flow-logs.html#flow-log-records Default: - default log format is used.

  • max_aggregation_interval (Optional[FlowLogMaxAggregationInterval]) – The maximum interval of time during which a flow of packets is captured and aggregated into a flow log record. When creating flow logs for a Transit Gateway or Transit Gateway Attachment, this property must be ONE_MINUTES. Default: - FlowLogMaxAggregationInterval.ONE_MINUTES if creating flow logs for Transit Gateway, otherwise FlowLogMaxAggregationInterval.TEN_MINUTES.

  • traffic_type (Optional[FlowLogTrafficType]) – The type of traffic to log. You can log traffic that the resource accepts or rejects, or all traffic. When the target is either TransitGateway or TransitGatewayAttachment, setting the traffic type is not possible. Default: ALL

  • resource_type (FlowLogResourceType) – The type of resource for which to create the flow log.

  • flow_log_name (Optional[str]) – The name of the FlowLog. Since the FlowLog resource doesn’t support providing a physical name, the value provided here will be recorded in the Name tag. Default: CDK generated name

Example:

# tgw: ec2.CfnTransitGateway

    resource_type=ec2.FlowLogResourceType.from_transit_gateway_id(tgw.ref)
)

Attributes

Default:

ALL
