SMon v2.0.1 - Bandwidth Fixes Release

Release Date: December 3, 2025

🚀 What's New in v2.0.1

This patch release addresses critical bandwidth monitoring accuracy issues, particularly for high-speed network interfaces.

🔧 Key Improvements

• Enhanced Counter Rollover Detection: Improved handling of SNMP counter rollovers for interfaces exceeding 100 Mbps
• 64-bit Counter Support: Added IF-MIB 64-bit counter support with automatic fallback to 32-bit counters
• Smart Traffic Classification: Better distinction between legitimate high-speed traffic and interface resets
• Multi-Rollover Detection: Support for detecting 1-20 counter rollovers for 10Gbps+ interfaces

🐛 Bug Fixes

• Fixed inaccurate bandwidth visualization for data exceeding 100 Mbps
• Resolved VLAN interfaces showing zero values due to false counter reset detection
• Fixed Ethernet/SFP+ interfaces not properly handling high-speed traffic
• Improved SNMP error handling and counter validation

📊 Technical Details

• Multiple rollover pattern matching for high-speed interfaces
• Enhanced delta calculation with proper polling interval accounting
• Better visualization scaling for high-bandwidth scenarios
• Reduced false positive counter resets

📈 Performance Improvements

• More accurate bandwidth calculations across all interface types
• Better chart rendering for high-traffic scenarios
• Improved data reliability for network monitoring

🔄 Migration Notes

• No breaking changes - fully backward compatible
• Automatic detection and use of 64-bit counters when available
• Existing configurations continue to work without modification

📋 Files Changed

• Updated version numbers across all UI components
• Enhanced counter rollover detection logic in app.js
• Improved SNMP polling with 64-bit counter support
