MAJOR ENHANCEMENTS: IP Enrichment Service (hyperglass/external/ip_enrichment.py): - Increase IXP data cache duration from 24 hours to 7 days (604800s) for better performance - Fix critical cache refresh logic: ensure_data_loaded() now properly checks expiry before using existing pickle files - Remove 'force' refresh parameters from public APIs and admin endpoints to prevent potential abuse/DDOS - Implement automatic refresh based on file timestamps and cache duration - Add comprehensive debug logging gated by Settings.debug throughout the module - Clean up verbose comments and improve code readability - Update configuration model to enforce 7-day minimum cache timeout MikroTik Traceroute Processing: - Refactor trace_route_mikrotik plugin to use garbage cleaner before structured parsing - Only log raw router output when Settings.debug is enabled to reduce log verbosity - Simplify MikrotikTracerouteTable parser to expect pre-cleaned input from garbage cleaner - Remove complex multi-table detection, format detection, and deduplication logic (handled by cleaner) - Add concise debug messages for processing decisions and configuration states Traceroute IP Enrichment (traceroute_ip_enrichment.py): - Implement concurrent reverse DNS lookups using asyncio.to_thread and asyncio.gather - Add async wrapper for reverse DNS with proper error handling and fallbacks - Significant performance improvement for multi-hop traceroutes (parallel vs sequential DNS) - Proper debug logging gates: only detailed logs when Settings.debug=True - Upgrade operational messages to log.info level (start/completion status) - Maintain compatibility with different event loop contexts and runtime environments Configuration Updates: - Update structured.ip_enrichment.cache_timeout default to 604800 seconds - Update documentation to reflect new cache defaults and behavior - Remove force refresh options from admin API endpoints MIGRATION NOTES: - Operators should ensure /etc/hyperglass/ip_enrichment directory is writable - Any code relying on force refresh parameters must be updated - Monitor logs for automatic refresh behavior and performance improvements - The 7-day cache significantly reduces PeeringDB API load PERFORMANCE BENEFITS: - Faster traceroute enrichment due to concurrent DNS lookups - Reduced external API calls with longer IXP cache duration - More reliable refresh logic prevents stale cache usage - Cleaner, more focused debug output when debug mode is disabled TECHNICAL DETAILS: - Uses asyncio.to_thread for non-blocking DNS operations - Implements process-wide file locking for safe concurrent cache updates - Robust fallbacks for various asyncio execution contexts - Maintains backward compatibility while improving performance FILES MODIFIED: - hyperglass/external/ip_enrichment.py - hyperglass/models/config/structured.py - hyperglass/api/routes.py - hyperglass/plugins/_builtin/trace_route_mikrotik.py - hyperglass/models/parsing/mikrotik.py - hyperglass/plugins/_builtin/traceroute_ip_enrichment.py - docs/pages/configuration/config/structured-output.mdx |
