What type of analysis does backtrace analysis provide?

Backtrace analysis is a method used to diagnose issues within applications by tracing the flow of requests through various services. It focuses on providing detailed insights about where errors or performance bottlenecks occur within a service mesh. By presenting an instance breakdown for each service, backtrace analysis highlights which service instances are being affected and how they are interacting with one another during a transaction. This level of detail allows developers and operators to pinpoint specific areas of concern, enabling more targeted troubleshooting and performance optimization.

The other answers do not accurately represent the specific purpose of backtrace analysis: summarizing user sessions pertains more to user experience metrics, comparing service performance over time measures trends rather than immediate causation of issues, and an overview of system resources used relates to general resource monitoring rather than the diagnostic insights provided by backtrace analysis.
