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. Default: 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. 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. It is not recommended to use an explicit name. Default: If you don’t specify a flowLogName, AWS CloudFormation generates a unique physical ID and uses that ID for the group name.
