## Summary by CodeRabbit

- **New Features**
- Introduced a new automated script for recording Java Flight Recorder
(JFR) data over a 24-hour period, enhancing monitoring capabilities for
Java applications.
- The script captures thread profiles at hourly intervals, streamlining
performance data collection without manual intervention.
- Added a monitoring setup function that conditionally executes the JFR
recording script based on environment configuration.
