health monitoring

[bomanaps]

What was wrong?

Issue #

How was it fixed?

Comprehensive Health Metrics: Implemented ConnectionHealth dataclass with latency tracking, success rates, bandwidth monitoring, and weighted health scoring.

Proactive Monitoring Service: Built ConnectionHealthMonitor with periodic health checks, real-time ping measurements, and automatic unhealthy connection replacement.

Health-Aware Load Balancing: Added four intelligent connection selection strategies, including health_based and latency_based, for optimal traffic routing.

API Consistency Fix: Extended new_host() to accept connection_config, resolving previous API inconsistency while maintaining full backward compatibility.
Summary of approach.

To-Do

• Clean up commit history
• Add or update documentation related to these changes
• Add entry to the release notes

Hi @seetadev this ci keeps failing but has nothing to do with the implementation i made, and also i had to create a new pr because there was a lot of changes that affected me when i git pulled

Hello @sumanjeet0012 @lla-dane @sukhman-sukh please can i get a review on this, thanks

@bomanaps Could you please share the link to the specification file or a reference to this feature in other libp2p implementations? It would be easier for me to understand what exactly we want to implement through this PR.

@bomanaps This is a fairly substantial PR, and there have already been extensive discussions surrounding it. I’ll need some additional time to review it thoroughly. I’m planning to go through it over the weekend.

@bomanaps Would you be able to share a basic screencast demonstrating the execution of health_monitoring_example.py? I'm currently facing some issues with dependency installation and haven't been able to run the example locally.

@bomanaps
Good work. Make a demo (something others members can see and appreciate health monitor new module features, could be as simple as a simple video showing examples and talking over. You could also do this online during the py-libp2p meeting)
See if you can address @sumanjeet0012 suggestions

🎉 Conclusion
The health monitoring branch has successfully implemented virtually ALL suggestions from the enhancement document, plus additional improvements!
The implementation is production-ready and provides:
✅ Sophisticated connection health tracking
✅ Proactive monitoring and automatic recovery
✅ Health-aware load balancing
✅ Comprehensive metrics and reporting
✅ Clean API integration
✅ Full documentation and examples
This represents a significant enhancement to Python libp2p's connection management capabilities, bringing it in line with the Go and JavaScript reference implementations as originally suggested.

Hey. Good try, but It's difficult to understands what's going on, without audio that comments over or subs or another format like presentation with slides

Isn't there something like a panel with real time info or something like that

Kidding, just something more clear at a glance

@bomanaps Are the failing test related or not ? do they fail on your local box with make pr ?

[bomanaps]

@seetadev merged something that caused ci to fail, this checked out d2c91f1

Maybe they randomly failed maybe are related. In my local linux box everything work

If we can re run the ci that will be good the logs iis not from my end make pr passes too, but the ci fail is showing test_provide_and_find_providers is checking that envelope_a
