The Continuous Profiler timeline view provides a detailed chronological visualization of code and runtime activity in production applications, allowing software engineers to pinpoint the root causes of performance issues more easily. This feature offers a complementary perspective to traditional flame graph views, breaking down activity by threads, fibers, goroutines, or event loops, filtered to a container or specific APM trace. With timeline view, engineers can review code-level activity within spans, observe CPU and I/O operations, detect non-parallelization, and analyze the impact of garbage collection on application performance. By using this feature in live production environments, engineers can identify and address inefficiencies that previously remained hidden during staging or local testing, shedding new light on the behavior of their services and helping to fine-tune them for optimal performance.
