Advanced Telemetry Features
This document outlines the advanced telemetry features that can be built upon the foundation established in Phases 1-4.
Phase 5: Advanced Analytics & Alerting
Performance Tracking and Analysis System
Real-Time Performance Metrics
- Sliding Window Aggregations: Calculate metrics over configurable time windows (1m, 5m, 15m, 1h)
- Percentile Calculations: Track p50, p90, p95, p99 latencies for all operations
- Rate Calculations: Requests per second, errors per minute, cache hit rates
- Resource Utilization Tracking: Memory, CPU, ETS table sizes, process counts
Historical Trend Analysis
- Time Series Storage: Store metrics in ETS/DETS for historical analysis
- Trend Detection: Identify performance degradation over time
- Capacity Planning: Project future resource needs based on growth patterns
- Seasonal Pattern Recognition: Detect daily, weekly, monthly patterns
Pattern Detection and Anomaly Detection
Statistical Anomaly Detection
- Z-Score Based Detection: Flag metrics that deviate >3 standard deviations
- Moving Average Comparison: Detect sudden changes in behavior
- Rate of Change Monitoring: Alert on rapid metric changes
- Correlation Analysis: Detect related metric anomalies
Machine Learning Integration
- Clustering: Group similar performance patterns
- Prediction Models: Forecast expected metric values
- Anomaly Scoring: ML-based anomaly confidence scores
- Root Cause Analysis: Correlate anomalies with system events
Alert System with Configurable Thresholds
Alert Configuration
%{
id: "high_error_rate",
metric: [:foundation, :service, :error],
condition: %{
type: :threshold,
operator: :gt,
value: 100,
window: :last_5_minutes
},
severity: :critical,
actions: [:log, :email, :webhook],
cooldown: 300_000 # 5 minutes
}
Alert Types
