public class CoalesceStatsEvent
extends SimpleTimer2.TimedEvent

Periodic statistics collection and aggregation system. This event runs every minute to collect, aggregate, and coalesce router performance statistics. It gathers metrics from all major router components and updates the statistics framework for monitoring and analysis. Statistics Collected:

• Network metrics - peer counts, bandwidth usage
• System resources - memory usage, CPU load, thread count
• Tunnel performance - build success rates, participation
• Router health - job queue lag, processing times
• Communication system - send/receive rates, error counts

Features:

• Automatic cache clearing when memory is low
• Rate calculation and rolling averages
• Performance trend monitoring
• Data available via /stats.jsp and /graphs.jsp

This data is essential for router performance monitoring, troubleshooting, and capacity planning. The statistics are used by the router console to display real-time performance graphs and historical trends.
