I would also be more explicit that keep_alive_interval is a configuration field, e.g., indicating that it's a field in the configuration file and specifying which section in the file the field belongs to.

It is better if they don't decrease this below 30 seconds because it will cause a high volume of logs so if we can be more opinionated with the language i'd prefer to recommend increasing the LB timeout.
