Problem Statement

Operations teams struggled with fragmented monitoring tools, alert fatigue from poorly tuned thresholds, and no correlation between metrics, logs, and traces.

Solution

Deployed a unified observability stack using Prometheus, Loki, Tempo, and Grafana with OpenTelemetry instrumentation. Implemented SLO-based alerting with multi-window burn rate alerts.

Technology Stack

Challenges

Managing cardinality explosion in high-traffic services
Designing meaningful SLOs that engineering teams actually use
Cost optimization for long-term metric and log retention

Lessons Learned

Start with USE/RED methods before building custom dashboards
Alert on symptoms (SLO burn rate), not causes (CPU > 80%)
OpenTelemetry auto-instrumentation covers 80% of needs
