In which scenarios is Micrometer used with Dynatrace?

Micrometer is a powerful library that provides a simple facade over instrumentation clients, allowing applications to track application metrics in a standardized way. It is primarily used to instrument application metrics, which enables developers to collect and expose various metrics relating to application performance, health, and behavior. By integrating with Micrometer, Dynatrace can automatically gather and analyze these metrics, providing insights into application performance and facilitating better monitoring and troubleshooting.

In the context of the mentioned options, the focus of Micrometer is on metrics, which effectively helps in understanding how an application is performing, identifying bottlenecks, and optimizing resource utilization. Other options, such as managing database connections, structuring application code, or controlling server hardware, do not align with the primary objective of Micrometer. Instead, those tasks involve different aspects of application development and infrastructure management that fall outside the scope of what Micrometer is designed to address.
