Module monitoring

Zero-latency monitoring framework for HFT trading systems

This module provides a high-performance monitoring solution designed for minimal impact on trading system latency. It uses lock-free data structures, async processing, and memory-mapped files for efficient metric collection and persistence.

Key Features

• Lock-free ring buffers for zero-allocation metric recording
• MPMC channels (flume) for async metric processing
• Memory-mapped files for low-latency persistence
• Nanosecond precision timing using quanta
• Support for counters, gauges, histograms, and latency measurements
