v1.1.99

🛰️ NodeSniff Linux Agent v1.1.99

Network accuracy update focused on reliable traffic measurement in environments with Docker, VPNs, and virtual interfaces.

✅ Improvements

• Introduced default route interface detection to identify the primary outbound network interface.
• Network traffic is now collected from the active interface instead of global system counters.
• Added smart fallback mechanism when default interface cannot be determined.
• Fallback aggregation now excludes non-relevant interfaces to avoid noisy data.
• Excluded virtual and auxiliary interfaces from traffic calculation:
  • loopback (lo)
  • Docker (docker*, br-*)
  • virtual interfaces (veth*)
  • tunnels (tun*, tap*)
  • VPN/WireGuard (wg*)
  • libvirt (virbr*)
  • ZeroTier / Tailscale (zt*, tailscale*)
• Added new metric field net_iface to indicate which interface is used for traffic measurement.
• Improved accuracy of network metrics across containerized and VPN-enabled systems.
• Preserved existing data collection and reporting logic — no behavioral changes.

⚙️ Version Info

• Agent version: 1.1.99
• Minimum dashboard version: unchanged (compatible with current releases)
• License: GPLv3 (non-commercial use)

v1.1.4

🛰️ NodeSniff Linux Agent v1.1.4

Maintenance & reliability update focused on logging, networking resilience, and modular extensibility.

✅ Improvements

• Introduced rotating log handler (max 256 KB per file, 3 backups) to prevent uncontrolled log growth.
• Added automatic cleanup of old logs older than LOG_RETENTION_DAYS (default: 7 days).
• Logs stored under /var/log/nodesniff/top_processes.log with consistent permissions.
• Improved public IP detection with multiple fallback providers to handle external service outages.
• Increased resilience of network lookups — agent no longer fails on single provider errors.
• Added informational log entry after each cache update for better traceability.
• Preserved existing data collection and reporting logic — no behavioral changes.
• Introduced modular metrics architecture — agent now supports pluggable metric modules.
• Added new disk.py metric module (beta) located under the metrics/ directory.
• Module documentation coming soon.
