What does the maintenance window setting exclude from regular baseline calculations?

The maintenance window setting is designed to help refine the accuracy of performance monitoring by specifying a period during which certain activities are excluded from regular baseline calculations. Specifically, when a maintenance window is defined, any anomalies detected during that period are excluded. This is critical because anomalies can skew the baseline metrics and lead to misinterpretation of performance during normal operational periods. By not factoring in anomalies from maintenance windows, organizations can ensure their baseline reflects true application performance, free from disruptions caused by planned maintenance activities.

The other options do not accurately represent what is excluded under the maintenance window setting. Performance metrics from the previous year, error logs, and metrics collected before the configuration are not part of the exclusion criteria for maintenance windows in the context of Dynatrace's baseline calculations. Rather, they may still play a role in historical data analysis or performance assessments outside of the specific maintenance period.
