What should alerts in Dynatrace focus on based on baseline calculations?

Alerts in Dynatrace should focus on significant performance degradations or excessive error rates, which aligns with option C. The baseline calculations provided by Dynatrace establish a normal performance level for applications based on historical data. When application performance deviates significantly from this baseline—such as when applications slow down or return excessive error rates—it can indicate underlying issues that need immediate attention.

Identifying alerts during these critical performance drops allows teams to respond proactively to potential problems before they impact users significantly. This approach ensures that the monitoring system prioritizes user experience and application reliability, focusing on the scenarios that could lead to user dissatisfaction or service disruptions.

Other options may touch on aspects of performance that are useful to consider but do not align with the primary focus of alerting based on baseline calculations. For instance, monitoring when the application performs within expected parameters does not necessitate an alert, while significant improvements in performance or increases in user interactions may not directly indicate issues that require immediate remediation. Instead, the focus should remain on alerting when there are signs of deterioration, making option C the most suitable choice.
