We use VMware Tanzu Observability (Wavefront) and Sentry to monitor our app infrastructure stack, providing real-time visibility into CPU, Memory, Network I/O, and Storage I/O. We also leverage Wavefront's native integrations with AWS services for resource monitoring and capacity planning. To monitor the Kubernetes stack, we utilize predefined dashboards and integrate Prometheus data using the Prometheus storage adapter. For logging, we use a centralized system to log customer exceptions and errors, which are then processed by Sentry for real-time alerting, exception tracking, and deduplication. Sentry enables us to respond quickly to bugs and exceptions, reducing our time to resolution from weeks to hours, and improving our overall quality of service.
