Microservices Observability

In distributed systems, observability is critical. Here's how to implement it properly.

The Three Pillars

1. Metrics

• Application performance metrics
• Infrastructure health
• Business KPIs

2. Logs

• Structured logging
• Centralized aggregation
• Real-time analysis

3. Distributed Tracing

• Request flow visualization
• Latency analysis
• Dependency mapping

Tools Stack

# Prometheus for metrics
# Loki for logs
# Tempo for traces
# Grafana for visualization

Implementation Tips

• Use correlation IDs
• Implement sampling strategies
• Set up meaningful alerts
• Create dashboards for each service

Results

Proper observability reduces:

• Mean time to detection (MTTD)
• Mean time to resolution (MTTR)
• Production incidents

Invest in observability early!
