Introducing Profiling for Golang
Released on: March 2026Atatus Profiling for Golang provides always-on, production-ready profiling for Go applications. Leveraging Go's built-in pprof runtime, Atatus continuously collects CPU, memory, goroutine, and mutex profiles with minimal performance overhead.
Teams can visualize execution hotspots with flame graphs, analyze goroutine contention, detect memory allocation patterns, and compare profiles across releases to ensure every deployment maintains optimal performance.
Key Features of Golang Profiling in Atatus:
- CPU Flame Graphs: Identify the most CPU-intensive functions across your Go services with interactive flame graphs and call tree visualizations.
- Memory Allocation Profiling: Track heap allocations per function, detect memory leaks, and optimize garbage collection pressure by identifying allocation-heavy code paths.
- Goroutine Profiling: Monitor active goroutines, detect goroutine leaks, and analyze contention on mutexes and channels to prevent concurrency bottlenecks.
- Differential Analysis: Compare profiles across deployments or time ranges to catch performance regressions introduced by code changes before they reach production.
- Minimal Overhead: Built on Go's native pprof runtime with less than 1% CPU overhead, safe for continuous collection in production environments without affecting application latency.
