Hi, I've had a dig around, but I can't seem to find it. Anyone know where I can see the disk space utilisation?We've set up a number of new apps in our environment recently, and I'm concerned we might be running out of space.

Hi Beeswing,I do not think you can find this directly and the reason behind is that the space increases automatically on Azure elastic pools. I think you could have a look under System > Environement>OS DB Server and do a filter on ElasticPoolStorageMB. That is the closest thing i can help with.Please give a kudo if it helps 🙂

Hi, Maybe. I just searched my email and it looks like it was provided as an XML file from OS cloud support team in July 2020. Send me a message with your email and I can forward it to you if you'd like.

Hi, you can check an individual database size with an extensibility rule containing code like this:Dim sql As String = "EXEC sp_spaceused;"Dim dbConnApp As DbConnInfoApp = brapi.Database.CreateApplicationDbConnInfo(si)Using dbConnAppUsing dt As DataTable = BRAPi.Database.ExecuteSql(dbConnApp, sql.ToString, True)If Not dt Is Nothing Then'Reference dt to access data table resultsFor Each dr As DataRow In dt.Rows'Process rowsbrapi.ErrorLog.LogMessage(si, "database_size: " + dr("database_size"))brapi.ErrorLog.LogMessage(si, "unallocated space: " + dr("unallocated space"))NextEnd IfEnd UsingEnd Using

Hello! We're on the cloud and this is how we review our application space: Bottom right corner of the dashboard lists the GB used by application in the environment where you've originated the dashboard (ie. DEV or PROD environments). Hope that's useful!

Hi, It's not a marketplace tool. Can you try searching your dashboards for "storage chart" and see if it's there?I assume it's out of the box OS as we didn't create it. If you can't find it, I'd suggest contacting your OS customer success/account manager or maybe submitting a OS support ticket for more direction.

I tried this solution, and it works perfectly for an application. It would show the size details for that specific app which is open. I am just wondering if it's possible to make this rule work for Environment level?

  Sandy: I am sure that is possible. We would just need to find the SQL stored command that would provide that information. I'll look around and see what I can find.

Sandy: The output of the code shows up in the System>Error Log. You will see two lines one for unallocated space, the other for database_size.

T_Kress: Thanks for sharing. I did download that application, but I couldn't get it to run on my version of 8.5. That is why I went the code direction.

Thanks,

  Thanks for providing this solution. I have a question, where i would see the results after running this business, Rule?
  
  Thank you

Hi, you can check an individual database size with an extensibility rule containing code like this:
Dim sql As String = "EXEC sp_spaceused;"
Dim dbConnApp As DbConnInfoApp = brapi.Database.CreateApplicationDbConnInfo(si)

Using dbConnApp
Using dt As DataTable = BRAPi.Database.ExecuteSql(dbConnApp, sql.ToString, True)
If Not dt Is Nothing Then
'Reference dt to access data table results
For Each dr As DataRow In dt.Rows
'Process rows
brapi.ErrorLog.LogMessage(si, "database_size: " + dr("database_size"))
brapi.ErrorLog.LogMessage(si, "unallocated space: " + dr("unallocated space"))
Next

End If
End Using

  Hi.. I know it's been a while, but hoping you could provide some more info.
  I don't have the Database Statistics Dashboard that you mentioned, and I can't find it on the market place. Is this one you created yourself? Or is it indeed from something in the market place?
  
  Thanks

Hi Beeswing,
I do not think you can find this directly and the reason behind is that the space increases automatically on Azure elastic pools. I think you could have a look under System > Environement>OS DB Server and do a filter on ElasticPoolStorageMB. That is the closest thing i can help with.
Please give a kudo if it helps 🙂
