/AWS1/CL_EC2=>CREATEFLOWLOGS()¶
About CreateFlowLogs¶
Creates one or more flow logs to capture information about IP traffic for a specific network interface, subnet, or VPC.
Flow log data for a monitored network interface is recorded as flow log records, which are log events consisting of fields that describe the traffic flow. For more information, see Flow log records in the Amazon VPC User Guide.
When publishing to CloudWatch Logs, flow log records are published to a log group, and each network interface has a unique log stream in the log group. When publishing to Amazon S3, flow log records for all of the monitored network interfaces are published to a single log file object that is stored in the specified bucket.
For more information, see VPC Flow Logs in the Amazon VPC User Guide.
Method Signature¶
IMPORTING¶
Required arguments:¶
IT_RESOURCEIDS TYPE /AWS1/CL_EC2FLOWLOGRESRCIDS_W=>TT_FLOWLOGRESOURCEIDS TT_FLOWLOGRESOURCEIDS¶
The IDs of the resources to monitor. For example, if the resource type is
VPC, specify the IDs of the VPCs.Constraints: Maximum of 25 for transit gateway resource types. Maximum of 1000 for the other resource types.
IV_RESOURCETYPE TYPE /AWS1/EC2FLOWLOGSRESOURCETYPE /AWS1/EC2FLOWLOGSRESOURCETYPE¶
The type of resource to monitor.
Optional arguments:¶
IV_DRYRUN TYPE /AWS1/EC2BOOLEAN /AWS1/EC2BOOLEAN¶
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is
DryRunOperation. Otherwise, it isUnauthorizedOperation.
IV_CLIENTTOKEN TYPE /AWS1/EC2STRING /AWS1/EC2STRING¶
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to ensure idempotency.
IV_DELIVERLOGSPERMISSIONARN TYPE /AWS1/EC2STRING /AWS1/EC2STRING¶
The ARN of the IAM role that allows Amazon EC2 to publish flow logs to the log destination.
This parameter is required if the destination type is
cloud-watch-logs, or if the destination type iskinesis-data-firehoseand the delivery stream and the resources to monitor are in different accounts.
IV_DELIVERCROSSACCOUNTROLE TYPE /AWS1/EC2STRING /AWS1/EC2STRING¶
The ARN of the IAM role that allows Amazon EC2 to publish flow logs across accounts.
IV_LOGGROUPNAME TYPE /AWS1/EC2STRING /AWS1/EC2STRING¶
The name of a new or existing CloudWatch Logs log group where Amazon EC2 publishes your flow logs.
This parameter is valid only if the destination type is
cloud-watch-logs.
IV_TRAFFICTYPE TYPE /AWS1/EC2TRAFFICTYPE /AWS1/EC2TRAFFICTYPE¶
The type of traffic to monitor (accepted traffic, rejected traffic, or all traffic). This parameter is not supported for transit gateway resource types. It is required for the other resource types.
IV_LOGDESTINATIONTYPE TYPE /AWS1/EC2LOGDESTINATIONTYPE /AWS1/EC2LOGDESTINATIONTYPE¶
The type of destination for the flow log data.
Default:
cloud-watch-logs
IV_LOGDESTINATION TYPE /AWS1/EC2STRING /AWS1/EC2STRING¶
The destination for the flow log data. The meaning of this parameter depends on the destination type.
If the destination type is
cloud-watch-logs, specify the ARN of a CloudWatch Logs log group. For example:arn:aws:logs:region:account_id:log-group:my_group
Alternatively, use the
LogGroupNameparameter.If the destination type is
s3, specify the ARN of an S3 bucket. For example:arn:aws:s3:::my_bucket/my_subfolder/
The subfolder is optional. Note that you can't use
AWSLogsas a subfolder name.If the destination type is
kinesis-data-firehose, specify the ARN of a Kinesis Data Firehose delivery stream. For example:arn:aws:firehose:region:account_id:deliverystream:my_stream
IV_LOGFORMAT TYPE /AWS1/EC2STRING /AWS1/EC2STRING¶
The fields to include in the flow log record. List the fields in the order in which they should appear. If you omit this parameter, the flow log is created using the default format. If you specify this parameter, you must include at least one field. For more information about the available fields, see Flow log records in the Amazon VPC User Guide or Transit Gateway Flow Log records in the Amazon Web Services Transit Gateway Guide.
Specify the fields using the
${field-id}format, separated by spaces.
IT_TAGSPECIFICATIONS TYPE /AWS1/CL_EC2TAGSPECIFICATION=>TT_TAGSPECIFICATIONLIST TT_TAGSPECIFICATIONLIST¶
The tags to apply to the flow logs.
IV_MAXAGGREGATIONINTERVAL TYPE /AWS1/EC2INTEGER /AWS1/EC2INTEGER¶
The maximum interval of time during which a flow of packets is captured and aggregated into a flow log record. The possible values are 60 seconds (1 minute) or 600 seconds (10 minutes). This parameter must be 60 seconds for transit gateway resource types.
When a network interface is attached to a Nitro-based instance, the aggregation interval is always 60 seconds or less, regardless of the value that you specify.
Default: 600
IO_DESTINATIONOPTIONS TYPE REF TO /AWS1/CL_EC2DSTOPTIONSREQUEST /AWS1/CL_EC2DSTOPTIONSREQUEST¶
The destination options.
