Flow Log Record

A flow log record is a record of a network flow in your VDC. By default, each record captures a network Internet Protocol (IP) Address traffic flow, groups it, and is enhanced with the following information:

• Account ID of the resource

• Unique identifier of the network interface

• The flow status, indicating whether it was accepted or rejected by the Software Defined Network (SDN) layer

The flow log record is in the following format:

<version> <account-id> <interface-id> <srcaddr> <dstaddr> <srcport> <dstport> <protocol> <packets> <bytes> <start> <end> <action> <log-status>

Available fields

The following table describes all of the available fields for a flow log record.

interface_id	string	The interface unique identifier (UUID) for which flow logs are collected.	7ffd6527-ce80-4e57-a949-f9a45824ebe2
srcaddr	string	The source address for incoming traffic, or the IPv4 address of the network interface for outgoing traffic.	172.17.1.100
dstaddr	string	The destination address for outgoing traffic, or the IPv4 address of the network interface for incoming traffic.	172.17.1.101
srcport	uint16	The source port from which the network flow originated.	59113
dstport	uint16	The destination port for the network flow.	20756

Flow log record example

The following are the examples of flow log records that capture specific traffic flows. For information on how to create flow logs, see Configure Flow Logs.

Accepted record

In this example, traffic to the network interface 7ffd6527-ce80-4e57-a949-f9a45824ebe2 for the account 12345678 is accepted.

2 12345678 7ffd6527-ce80-4e57-a949-f9a45824ebe2 172.17.1.100 172.17.1.101 59113 20756 6 17 1325 1587983051 1587983052 ACCEPT OK

Rejected record

In this example, traffic to the network interface 7ffd6527-ce80-4e57-a949-f9a45824ebe2 for the account 12345678 is rejected.

2 12345678 7ffd6527-ce80-4e57-a949-f9a45824ebe2 172.17.1.100 172.17.1.101 59113 20756 6 17 1325 1587983051 1587983052 REJECT OK
