What is the best way to detect memory leak in go micro service running on production

Question

I need to know some efficient way / tools in golang that will help us to detect memory leak in the micro service that is live and running on production

Answer 1

One thing you can do is to compare 2 heap pprofs. You can do it like this:

• Extract a heap profile heap0.pprof
• Add some load to the application
• Extract another heap profile heap1.pprof
• Compare them with go tool pprof -base heap0.pprof heap1.pprof

This way you can see exactly what is increasing over time.
