Summary of Changes
Hello @Mou887, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've updated the documentation for profiling Karmada to make the usage examples for go tool pprof clearer and easier to follow. This change specifically adds quick how-to commands for go tool pprof to analyze top CPU and memory consumers, improving the overall clarity of the profiling guide.
Highlights
- Documentation Improvement: Added specific
go tool pprof -topcommands for analyzingheap.pprof(memory) andcpu.pprof(CPU) profiles, making the profiling guide more explicit and easier to follow. - Clarity for Profiling Data Analysis: Enhanced the "Analyze the data" section in the
profiling-karmada.mddocument to provide direct commands for commonpprofanalysis tasks, alongside the existing interactive mode instruction.

Code Review
This pull request enhances the profiling documentation by adding specific go tool pprof command examples for analyzing heap and CPU profiles. The new instructions are a definite improvement. I've included one suggestion to make the section on interactive analysis more explicit and consistent with the other examples.

| go tool pprof -top cpu.pprof | ||

This is a great addition to the documentation. For improved clarity and consistency with the -top examples above, consider explicitly mentioning that interactive mode works for both heap and CPU profiles. The current text might lead the reader to believe it only works for the heap profile shown in the example that follows.
