Sometimes you need to use the SQL queries to get the performance data instead of using WUG Reports. You can use the following queries to get the required data for Memory utilization.
SELECT Device.nDeviceID, Device.sDisplayName, sType, nSize, nUsed_Avg, nUsed_Min, nUsed_Max, dPollTime
FROM dbo.StatisticalMemory
LEFT OUTER JOIN dbo.StatisticalMemoryIdentification ON
StatisticalMemoryIdentification.nStatisticalMemoryIdentificationID = StatisticalMemory.nStatisticalMemoryIdentificationID
LEFT OUTER JOIN dbo.PivotStatisticalMonitorTypeToDevice ON
PivotStatisticalMonitorTypeToDevice.nPivotStatisticalMonitorTypeToDeviceID = StatisticalMemoryIdentification.nPivotStatisticalMonitorTypeToDeviceID
LEFT OUTER JOIN Device ON
Device.nDeviceID = PivotStatisticalMonitorTypeToDevice.nDeviceID
ORDER BY dPollTime DESC
Memory Cache data, the latest Memory utilization data (i.e exactly one record per monitored Memory)
SELECT Device.nDeviceID, Device.sDisplayName, sType, nSize, nUsed_Avg, nUsed_Min, nUsed_Max, dPollTime
FROM dbo.StatisticalMemoryCache
LEFT OUTER JOIN dbo.StatisticalMemoryIdentification ON
StatisticalMemoryIdentification.nStatisticalMemoryIdentificationID = StatisticalMemoryCache.nStatisticalMemoryIdentificationID
LEFT OUTER JOIN dbo.PivotStatisticalMonitorTypeToDevice ON
PivotStatisticalMonitorTypeToDevice.nPivotStatisticalMonitorTypeToDeviceID = StatisticalMemoryIdentification.nPivotStatisticalMonitorTypeToDeviceID
LEFT OUTER JOIN Device ON
Device.nDeviceID = PivotStatisticalMonitorTypeToDevice.nDeviceID
ORDER BY dPollTime DESC
