Discover how to identify and resolve performance issues in Java code using Digma, a free IDE plugin, in this 36-minute Devoxx conference talk. Learn about Digma's utilization of OpenTelemetry to collect and analyze traces and metrics, enabling the detection of scaling problems, bottlenecks, N+1 Selects, and other inefficiencies. Explore the benefits of coding with OpenTelemetry feedback for improved practices and early issue detection. Understand that no prerequisites, prior instrumentation, or code changes are required to start using Digma, with all analysis performed locally on your machine.
