What Will Be Covered
Built-in Go Tools
go tool pprof
- Type: Built-in profiling tool
- Features: CPU, memory, goroutine profiling
- Usage: Interactive and programmatic analysis
- Integration: Web interface, command-line analysis
go tool trace
- Type: Execution tracer
- Features: Goroutine analysis, GC visualization
- Use Cases: Performance debugging, concurrency analysis
- Output: Interactive web-based trace viewer
runtime/pprof Package
- Type: Programmatic profiling
- Features: Custom profile collection
- Integration: Application-embedded profiling
- Flexibility: Runtime profiling control
net/http/pprof Package
- Type: HTTP endpoint profiling
- Features: Live profiling via web endpoints
- Endpoints:
/debug/pprof/heap,/debug/pprof/goroutine - Production: Safe for production use

Memory Analysis Techniques
Heap Profiling
go
// Basic heap profiling
import _ "net/http/pprof"
import "net/http"
go func() {
log.Println(http.ListenAndServe("localhost:6060", nil))
}()Goroutine Analysis
go
// Goroutine profiling
runtime.SetBlockProfileRate(1)
runtime.SetMutexProfileFraction(1)Custom Monitoring
go
// Memory statistics monitoring
var m runtime.MemStats
runtime.ReadMemStats(&m)Automation and CI/CD
Automated Testing
- Memory leak detection in tests
- Performance regression testing
- Benchmark comparisons
- CI/CD integration
Profile Analysis Automation
- Automated profile collection
- Regression detection
- Alert generation
- Report automation
Best Practices
Tool Selection
- Development: pprof, trace, IDE integration
- Production: Continuous profiling, metrics monitoring
- CI/CD: Automated benchmarks, profile comparison
- Debugging: Interactive pprof analysis
Monitoring Strategy
- Baseline Establishment: Normal memory patterns
- Threshold Monitoring: Memory usage alerts
- Trend Analysis: Long-term memory growth
- Incident Response: Profile collection automation
