Tinder, the popular dating app, has successfully integrated Grafana and Prometheus into its monitoring infrastructure to manage its expansive microservices environment. Originally relying on AWS CloudWatch for metrics monitoring, Tinder transitioned to using Grafana for data visualization and Prometheus for tracking service metrics, due to their scalability and lack of drawbacks found in other solutions. As the app's services grew, Tinder moved to a more scalable setup with individual Prometheus servers for each service and an archive server for long-term data retention. To enhance operational efficiency, Tinder migrated its infrastructure to a Kubernetes environment, utilizing Prometheus Operator for effective monitoring of applications across different namespaces. The Observability Team further optimized the process by developing customized dashboard automation tools using GrafanaLib, ensuring efficient monitoring across various test environments. This strategic evolution has fortified Tinder's observability capabilities, enabling it to maintain robust service health monitoring as its platform continues to expand.
