+# Advanced Analytics Agent Specification
+
+## Overview
+The Advanced Analytics Agent provides comprehensive monitoring, custom metrics, role-based reporting, and system health tracking. This module integrates with UI interfaces and backend services for real-time analytics and historical trend analysis.
+
+## Configuration
+Analytics configuration is defined in [`docs/configs/analytics_config.json`](./analytics_config.json)
+
+## Features
+
+### Custom Metrics
+- **User Engagement Score**: Composite metric tracking active user ratios and session duration
+  - Formula: `(active_users * avg_session_duration) / total_users`
+  - Warning threshold: 0.3
+  - Critical threshold: 0.15
+- **API Response Time (P95)**: Performance metric for API latency monitoring
+  - Unit: milliseconds
+  - Warning threshold: 500ms
+  - Critical threshold: 1000ms
+- **Error Rate**: Reliability metric tracking system errors
+  - Unit: percentage
+  - Warning threshold: 2%
+  - Critical threshold: 5%
+- **Resource Utilization**: System metrics for CPU, memory, disk, and network usage
+  - Components: cpu, memory, disk, network
+  - Warning threshold: 75%
+  - Critical threshold: 90%
+
+### Notifications
+Multi-channel notification system with severity-based routing:
+- **Email**: Alerts sent to admin and ops team for warning/critical events
+- **Slack**: Critical alerts posted to #analytics-alerts channel
+- **Webhooks**: All severity levels sent to configured webhook endpoint
+- **Rate Limiting**: Maximum 10 notifications per hour with 15-minute cooldown
+
+### Role-Based Views
+Four distinct role configurations with tailored permissions and dashboards:
+
+#### Administrator
+- **Permissions**: view_all, configure, export, delete

+
+### Batch Processing
+Scheduled operations for data aggregation and reporting:
+- **Daily Aggregation**: Runs at 2:00 AM, outputs parquet format, 365-day retention
+- **Weekly Report**: Runs Monday 3:00 AM, generates PDF for leadership
+- **Data Cleanup**: Runs Sunday 1:00 AM, purges data older than 90 days
