Service Update 2021-10-13
New Features
- Containerized OtterTune Agent - we support an open-source agent running on your hosts that can collect database metrics without our service needing direct network access to your database.
- CloudFormation templates - it is now much easier to provision your OtterTune IAM role and the agent

- Customizable Tuning Schedules - control when OtterTune is able to optimize your database

Bug Fixes
- Fixed issue where we were always treating changes to the MySQL parameter
innodb_thread_sleep_delayas new configuration changes. This parameter is updated by InnoDB automatically wheninnodb_adaptive_max_sleep_delayis set. Now, we no longer treat automatic changes toinnodb_thread_sleep_delayas a new configuration. - Fixed y-axis issue on charts where we were not appropriately subdividing for small ranges
- Fixed issue where we would incorrectly display an error message suggesting that users' agents have been disconnected if they stayed on the database overview page for too long.
- Fixed issue where we lost track of a user's parameter group ARN when they switched from Tuning mode to Monitoring mode.
