[Go] Go pprof in Kubernetes: Remote CPU & Memory Profiling Without Restarting Pods
📰 Dev.to · Tuấn Anh
Learn to use Go pprof for remote CPU and memory profiling in Kubernetes without restarting pods, and understand how to safely expose pprof endpoints in production
Action Steps
- Import the net/http/pprof package to enable profiling
- Run the pprof server in a background goroutine on a separate internal port
- Configure the pprof server to minimize performance overhead
- Use the pprof tool to sample CPU and memory usage and identify performance bottlenecks
- Analyze the profiling data to diagnose and fix performance issues
Who Needs to Know This
DevOps and software engineering teams can benefit from this knowledge to diagnose and fix performance issues in production Go services, and ensure smooth operation of their applications
Key Insight
💡 Safe exposure of pprof endpoints in production is crucial to prevent diagnostic data from being exposed to the public internet
