The integration of Database Monitoring (DBM) and Application Performance Monitoring (APM) allows for seamless linkage of telemetry data from both sources, enhancing visibility and streamlining troubleshooting processes. By using DBM and APM together, application developers can gain insights into database performance without direct access to the database, while Database Administrators (DBAs) can understand how request traffic from specific services affects the database load. This integration enables developers to collaborate more effectively with DBAs in identifying and mitigating issues related to database performance.
