One or more filters.

deliver-log-status - The status of the logs delivery (SUCCESS | FAILED).
log-destination-type - The type of destination to which the flow log publishes data. Possible destination types include cloud-watch-logs and s3.
flow-log-id - The ID of the flow log.
log-group-name - The name of the log group.
resource-id - The ID of the VPC, subnet, or network interface.
traffic-type - The type of traffic (ACCEPT | REJECT | ALL).
tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.
tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

Type: Integer

Required: No

NextToken

The token for the next page of results.

Type: String

Required: No
