- Navigate to the Logs tab.
- Select the number of messages per page and the time interval: 1 hour, 3 hours, 1 day, 1 week, 2 weeks.

You can also view logs in Yandex Cloud Logging:
Management console

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.
To see the messages in JSON format, run this command:
yc logging read \
--group-name=<log_group_name> \
--format=json
Where:
--group-name: Name of the log group receiving your load balancer logs.--format: Log output format.
