baseline reports?

Don't think it shows up anywhere in the GUI driven report builder but this SWQL query will get you the raw data for all the baselines for Nodes, Interfaces, and Volumes.  You can filter it out from here and get exactly what you need.

SELECT TOP 1000 NodeID, EntityType, InstanceId, MetricId, MetricName, InstanceCaption, ThresholdType, Timestamp, MinDateTime, MaxDateTime, CurrentValue, WarningThreshold, CriticalThreshold, CapacityThreshold, Aavg, Bavg, Apeak, Bpeak, DaysToWarningAvg, DaysToCriticalAvg, DaysToCapacityAvg, DaysToWarningPeak, DaysToCriticalPeak, DaysToCapacityPeak, InstanceUri, DetailsUrl, DisplayName, Description, InstanceType, Uri, InstanceSiteId

FROM Orion.ForecastCapacity

Thanks mesverrum​!  I'll give that a shot and report back.
