This update introduces a Technology Preview of the security group logging feature in RHOSP 16.2.6. To monitor traffic flows and attempts into and out of an instance, you can configure Networking service packet logging for security groups. + You can associate any instance port with one or more security groups and define one or more rules for each security group. For example, you can create a rule to drop inbound SSH traffic to any instance in the finance security group. You can create another rule to allow instances in that group to send and respond to ICMP (ping) messages. Then you can configure packet logging to record combinations of accepted and dropped packet flows. + In 16.2, you can use security group logging for stateful security groups. Logged events are stored on the Compute nodes that host the instances, in the file `/var/log/containers/stdouts/ovn_controller.log`. + For more information about Technology Preview features, see https://access.redhat.com/support/offerings/production/scope_moredetail[Scope of Coverage Details]. + For more information about security group logging known issues and workarounds, see https://bugzilla.redhat.com/show_bug.cgi?id=2241184 and https://bugzilla.redhat.com/show_bug.cgi?id=2192918.
