Under what condition does Dynatrace generate a new problem for synthetic monitoring?

Dynatrace generates a new problem for synthetic monitoring when a monitor exceeds performance thresholds in a specified number of recent executions. This approach helps ensure that issues are identified based on consistent performance degradation rather than isolated incidents. By requiring multiple executions to meet the threshold criteria, the system minimizes the noise from transient issues that might not indicate a persistent problem.

This method enhances reliability by confirming that the performance metrics are consistently problematic, thus providing more accurate insights into the application's health. A threshold of 3 out of 5 executions effectively balances sensitivity to performance issues and reduces the likelihood of false positives, ensuring that alerts are meaningful and actionable.

The other options do not align with the performance threshold-based methodology that Dynatrace employs. For example, manual checks and user reports are subjective and may not represent the overall monitoring objective, whereas generating a report for every single execution would lead to excessive noise and alerts, hampering the monitoring effectiveness.
