Exchange 2013 SP1 with 2 member DAG. Trying to use collectovermetrics. When running .\collectovermetrics -generatehtmlreport I get:

PS C:\Program Files\Microsoft\Exchange Server\V15\Scripts> .\collectovermetrics.ps1 -GenerateHtmlReport
cmdlet CollectOverMetrics.ps1 at command pipeline position 1
Supply values for the following parameters:

Summary report is C:\Program Files\Microsoft\Exchange Server\V15\Scripts\FailoverSummary.2015_05_16_22_05_39.htm

So you can see the report is 0 and size is 0kb. As far as I know this script is unmodified. Why are the entries in the DAG 0 which I suppose is why the report is 0kb in size?

Hello,

Can you try this with different parameters as shown in the following example?

CollectOverMetrics.ps1 -DatabaseAvailabilityGroup DAG1 -StartTime "06/15/2012" -EndTime "06/16/2012" -GenerateHTMLReport send-mailmessage -to user@domain.tld -from user2@domain.tld -subject "this is a test" -smtpserver "FQDN of mail server"

Also, check if this is something related to a permission issue. Check with ReportPath parameter and specify a path to generate the report

So that gives the exact same error. Even just used CollectOverMetrics.ps1 -DatabaseAvailabilityGroup DAG1 -StartTime "05/15/2015" -EndTime "05/16/2015" -GenerateHTMLReport

Also, check if this is something related to a permission issue. Check with ReportPath parameter and specify a path to generate the report

Move all 3 collectovermetrics files to the scripts folder where I know I have proper permissions and ran the above command = same error
