Which errors does Dynatrace detect by default as reasons for failed requests?

Dynatrace is designed to provide comprehensive monitoring of application performance, which includes the detection of various errors that can lead to failed requests. By default, Dynatrace identifies both programming exceptions, which are runtime errors that occur during the execution of application code, and HTTP error codes within the range of 400 to 599.

This range encompasses client-side errors (HTTP 400-499) indicating that the request made by the client was incorrect or could not be processed, and server-side errors (HTTP 500-599) indicating that the server encountered an unexpected condition. The ability to detect these errors allows developers and operations teams to quickly identify issues in the application that may result in user dissatisfaction or performance degradation.

The inclusion of both programming exceptions and HTTP error codes broadens the scope of error detection, enabling a more holistic view of application health and aiding in the troubleshooting process. Recognizing these common categories of errors is crucial for maintaining application reliability and ensuring a better user experience.
