If you suspect a specific struct is leaking, say UserSession , you can filter the output: xdumpgo types heap.dump | grep UserSession Use code with caution. Part 4: Advanced Analysis - Finding Leaks
Use pprof to find where in the code memory is allocated, and xdumpgo to understand why it wasn't freed.
If you are interested in exploring how to use pprof alongside xdumpgo , I can create a comparison guide for you. Would that be helpful?
Mastering eXtended Dump in Go: The Ultimate Xdumpgo Tutorial for High-Quality Data Debugging
Let's use a dumper to make this readable. xdumpgo tutorial extra quality

Specify tables you want to fully dump:
This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.
Use the --ignore-errors flag to force the tool to skip unreadable bytes and keep processing the rest of the file. To help refine this guide for your project, tell me: What specific operating system are you targeting? If you suspect a specific struct is leaking,
Before we dive into advanced features, let’s set up xdumpgo . The package is part of the github.com/Kretech/xgo module, specifically the dump sub-package.
./xdumpgo dump \ --pid 1234 \ --output high_quality.dump \ --full-page \ --ignore-paged \ --preserve-perms \ --verify-checksum \ --thread-sync
Capture a dump at startup, and another after a workload. Compare the differences to see what grew, rather than just what is large.
Since XDumpGO by Zertex has had its source code leaked multiple times, your safest bet is to build from verified sources or use more established alternatives like xdump (Python) or xgo/dump (Go). For this tutorial, we'll cover both approaches. Would that be helpful
Compression balances dump file size against speed. For extra quality backups where space isn't a concern, use ZIP_STORED (no compression) for fastest operation:
Load this into GDB:
func main() u := UserName: "Alice", Email: "alice@example.com", Roles: []string"Admin", "Editor" fmt.Printf("%+v\n", u)
