You can configure the delivery of L7 load balancer logs to a Yandex Cloud Logging log group.
To view logs of the L7 Load balancer:
Management console
- In the management console, select the folder where the load balancer was created.
- Select Application Load Balancer.
- Select the load balancer to view logs for.
- Go to the Logs tab.
- Select the number of messages per page and the period: 1 hour, 3 hours, 1 day, 1 week, 2 weeks.
- To view full information about the message, click the arrow at the beginning of the row.
You can also view logs in Yandex Cloud Logging:
Management console

API
- In the management console, select the folder containing your log group.
- Select Cloud Logging.

If you do not have the Yandex Cloud CLI yet, install and initialize it.
The folder specified in the CLI profile is used by default. You can specify a different folder through the --folder-name or --folder-id parameter.

--group-name=<log_group_name> \
--format=json
