When configuring custom exceptions, which of the following is essential for them to be picked up by Dynatrace?

For custom exceptions to be effectively tracked and monitored by Dynatrace, they need to be configured within the Dynatrace platform. This configuration allows Dynatrace to recognize the exceptions that occur in your application, which is crucial for providing insights and alerting based on these exceptions.

When you configure custom exceptions, you typically specify certain parameters like the type of exceptions to monitor and how they should be represented in the Dynatrace interface. This process ensures that the Dynatrace monitoring system is aware of these exceptions and can analyze their occurrences, impact, and trends over time.

While it is important that exceptions are defined in the application code so that they can be thrown by the application, the essential step that links those exceptions to Dynatrace's monitoring capabilities is the configuration within the Dynatrace platform itself. Logging them in a text file is not a requirement for Dynatrace to pick them up, nor is it necessary that they be tested separately for monitoring purposes. Thus, configuring them directly in Dynatrace is the critical step for visibility and tracking.
