What does the term "Composite metrics" refer to in the context of application errors?

The term "Composite metrics" in the context of application errors refers to aggregated response times. Composite metrics are derived from multiple individual metrics to provide a broader view of application performance. In this case, aggregated response times combine various response times from individual transactions or services into one metric, allowing for a coherent analysis of application performance and the occurrence of errors.

By focusing on aggregated response times, teams can gain insights into the overall responsiveness of the application, identify trends, and detect potential issues that could lead to application errors. This approach helps in understanding the performance impact of different components and is critical for diagnosing and resolving errors effectively.

The other terms mentioned, while they may relate to performance metrics in different contexts, do not encapsulate the concept of composite metrics as accurately as aggregated response times do.
