Learn to identify common performance problems in distributed applications by analyzing logs and traces to detect inefficient database queries (N+1 patterns), excessive logging per request, problematic exceptions, and CPU hotspots in internal methods. Explore the Dynatrace Distributed Traces and Logs interface to spot these patterns, then advance to using DQL (Dynatrace Query Language) to join traces and logs for deeper analysis. Master practical tips and tricks for pattern detection including database query optimization, exception handling analysis, method performance hotspot identification, and log pattern recognition. Discover how to leverage the Dynatrace Notebook feature for systematic analysis and gain hands-on experience with advanced querying techniques that combine multiple data sources to troubleshoot distributed system performance issues effectively.
