Exchange DAG Failover Report - CollectOverMetrics.ps1

Below is my quick command that requires no customization to run on any installation:

• Get-DatabaseAvailabilityGroup |%{ .\CollectOverMetrics.ps1 -DatabaseAvailabilityGroup "$($_.name)" -StartTime ((get-date).AddDays(-365)) -EndTime ((get-date)) -MergeCSVFiles}

Note that this script is located in the "Scripts" directory of your Exchange v15 installation.
