Monitoring & Observability
The Posters.science platform implements a comprehensive monitoring and observability stack to ensure system health, performance, and security. This section covers the monitoring infrastructure, tools, and practices used to maintain platform reliability.
Key Components
- Application Monitoring: Real-time performance and health tracking
- Logging: Centralized log management and analysis
- Error Tracking: Comprehensive error monitoring and alerting
- User Analytics: Privacy-friendly usage analytics
- Data Backups: Automated backup and recovery systems
- Email Services: Transactional email monitoring
Monitoring Architecture
System Overview
Application Monitoring
Prometheus or server-native monitoring tracks backend health:
- API latency
- Search indexing
- LLM performance
- Job completion
Alerts route via email or Slack. Synthetic monitoring tests end-to-end workflows.
Logging
Grafana Loki (or Azure Log Analytics) centralizes logs including:
- Request traces
- Job results
- Errors
Error Tracking
Sentry monitors real-time errors across Nuxt frontend and server-side APIs, capturing exceptions and broken flows.
User Analytics
Umami tracks anonymous usage metrics:
- Searches
- Metadata corrections
- LLM queries
Data Backups
Nightly Postgres backups export to Cloudflare R2 storage, covering:
- Metadata
- poster.json versions
- Sessions
- Embeddings
Email Services
Resend handles transactional emails:
- Verification
- Password resets
- DOI confirmations
Implementation Strategy
Tool Selection Criteria
- Open Source: Cost-effective and customizable solutions
- Integration: Seamless integration with existing stack
- Scalability: Growth-ready monitoring infrastructure
- Privacy: User privacy protection and compliance
Incremental Rollout
Tools will be introduced incrementally based on deployment scale, starting with health checks and Sentry integration.
