We Ditched New Relic for Grafana 10 and Loki 2.9: 60% Monitoring Cost Savings

In Q3 2023, our 14-person platform team was spending $42,000 per month on New Relic for a modest 120-microservice Kubernetes fleet processing 2.1M requests per second. By Q1 2024, we’d cut that bill to $16,800 monthly—a 60% reduction—after migrating 100% of our observability stack to Grafana 10, Loki 2.9, and Prometheus 2.47. This isn’t a hobbyist experiment: we’re running production workloads for 3.2M monthly active users, with 99.99% uptime SLA penalties that cost us $12k per hour of downtime.
