Using CloudWatch Database Insights to troubleshoot query performance from calling services
CloudWatch Database Insights' calling services feature lets you identify which application services are driving database load by correlating application telemetry (via Application Signals and X-Ray) with database performance metrics in a single console. A walkthrough demonstrates enabling Database Insights Advanced mode, Application Signals, and Transaction Search, then tracing a production incident where a Lambda function's polling loop caused 165x vCPU DB load on an Aurora PostgreSQL instance — identifying the root cause (a missing backoff in a deployment) in minutes without cross-team coordination. The post covers setup steps, a realistic incident scenario with specific metrics, and important limitations around supported engines, pricing, and SQL text capture.
