Flow log record
A flow log record is a record of a network flow in your virtual data center (VDC). By default, each record captures a network internet protocol (IP) traffic flow, groups it, and is enhanced with the following information:
Account ID of the resource
Unique identifier of the network interface
The flow's status, indicating whether it was accepted or rejected by the software-defined networking (SDN) layer
The flow log record is in the following format:
Available Fields
The following table describes all of the available fields for a flow log record.
Field | Type | Description | Example Value |
---|---|---|---|
| string | The flow log version. Version 2 is the default. | 2 |
| string | The IONOS Cloud account ID of the owner of the resource containing the interface for which flow logs are collected. | 12345678 |
| string | The interface unique identifier (UUID) for which flow logs are collected. | 7ffd6527-ce80-4e57-a949-f9a45824ebe2 |
| string | The source address for incoming traffic, or the IPv4 address of the network interface for outgoing traffic. | 172.17.1.100 |
| string | The destination address for outgoing traffic, or the IPv4 address of the network interface for incoming traffic. | 172.17.1.101 |
| uint16 | The source port from which the network flow originated. | 59113 |
| uint16 | The destination port for the network flow. | 20756 |
| uin8 | The Internet Assigned Numbers Authority (IANA) protocol number of the traffic. For more information, see Assigned Internet Protocol Numbers | 6 |
| uint64 | The number of packets transferred during the network flow capture window. | 17 |
| uint64 | The number of bytes transferred during the network flow capture window. | 1325 |
| string | The timestamp, in UNIX EPOCH format, of when the first packet of the flow was received within the grouping interval. | 1587983051 |
| string | The timestamp, in UNIX EPOCH format, of when the last packet of the flow was received within the grouping interval. | 1587983052 |
| string | The action associated with the traffic: ACCEPT: traffic accepted by the firewall REJECT: traffic rejected by the firewall | ACCEPT |

Flow log record example
The following are 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
was accepted.
Rejected record
In this example, traffic to the network interface 7ffd6527-ce80-4e57-a949-f9a45824ebe2
for the account 12345678
was rejected.
