Eavesdropper: Intelligent Systems Monitoring
A comprehensive systems monitoring solution that provides real-time insights into application health, performance, and uptime.
The Brief
Modern applications require constant monitoring to ensure reliability and performance. While solutions like Oh Dear exist, there's a need for flexible, self-hosted monitoring tools that provide deep insights without vendor lock-in.
The Challenge:
- Need for comprehensive systems monitoring
- Real-time alerting for critical issues
- Performance tracking and trend analysis
- Self-hosted solution for data sovereignty
The Strategy
Build a monitoring platform that combines uptime checks, performance metrics, and intelligent alerting into a unified system. The focus was on providing actionable insights while maintaining simplicity and reliability.
Why This Architecture:
Self-hosted monitoring provides complete control over data and infrastructure. By building a modular system, we enable customisation for specific monitoring needs while maintaining a clean, focused core.
The Execution
Uptime Monitoring
Implemented robust uptime checks with configurable intervals and multiple check types (HTTP, HTTPS, TCP, ping). Tracks response times and availability patterns.
Performance Metrics
Built comprehensive performance tracking including response times, resource usage, and application-specific metrics. Historical data enables trend analysis and capacity planning.
Intelligent Alerting
Created a flexible alerting system that notifies teams through multiple channels (email, Slack, webhooks) based on configurable thresholds and escalation rules.
Real-time Dashboard
Developed an intuitive dashboard providing at-a-glance system health status and detailed drill-down capabilities for investigation.
Self-Hosted Architecture
Designed for easy deployment and maintenance, with minimal dependencies and clear documentation for self-hosting.
The Result
Eavesdropper provides comprehensive systems monitoring with the flexibility and control of self-hosting.
Outcomes:
- Complete visibility into system health and performance
- Proactive issue detection through intelligent alerting
- Data sovereignty through self-hosted deployment
- Reduced monitoring costs compared to SaaS solutions
- Customisable monitoring for specific infrastructure needs
