The text discusses the challenges and evolution of failure rate analysis in software applications, highlighting the author's past experiences with manual log file inspections and the introduction of Logstash, which improved the process by providing a visual dashboard for log errors. Despite Logstash's advantages, the author felt that it didn't fully address the need for detailed failure analysis across different parts of the application. The text introduces Dynatrace as an alternative solution that automatically gathers exceptions directly from the application, categorizes errors, and provides detailed insights into HTTP status codes and related requests, facilitating a more comprehensive analysis. The author appreciates both tools, noting that while log files and Logstash are useful for understanding user behavior and specific log lines, Dynatrace excels in providing an overall view of application exceptions. The text concludes by encouraging readers to try Dynatrace with an extended free trial to explore its capabilities.
