What type of information does a service map provide in APM?

A service map in Application Performance Monitoring (APM) is designed to illustrate the architecture of an application by showing how different services interact and the flow of data between those services. This visual representation helps teams understand the dependencies and relationships among various components of an application. By providing insights into service interactions, it enables teams to identify bottlenecks, optimize performance, and troubleshoot issues more effectively.

This type of visualization is critical for DevOps and operations teams as it promotes a deeper understanding of how services communicate, which is essential for maintaining the health and efficiency of an application. While other types of information, such as memory usage, user interactions, or error rates, are valuable for performance monitoring, they do not specifically relate to the structural overview that a service map provides.
