General
SQL Diagnostic Manager displays a refresh error when a user attempts to view data for an instance to which he does not have admin rights
SQL Diagnostic Manager displays a refresh error message when a user tries to view data for a monitored SQL Server instance to which the user does not have administrative rights. The message states that, "An error occurred while refreshing the active view."
SQL Diagnostic Manager displays an error when a user attempts to configure disk collection for an instance to which he does not have admin rights
SQL Diagnostic Manager displays an error message on the Server Properties Disk Drives window if a user's collection service credentials do not have administrative access to the monitored SQL Server instance, and the user attempts to view the list of attached disk drives on that instance. Note that WMI credentials are not used to retrieve disk drive information on this page.
Drives may not appear in the Resources Disk view when you switch to direct WMI collection
Users who select to collect OS metrics using direct WMI collection may notice mounted drives appearing in some areas of SQL Diagnostic Manager but not on the Resources Disk view. To refresh this list, you must restart the SQL Diagnostic Manager Management Console.
Dashboard
Custom Counters dashboard panel does not return to default after deleting all counters
The Custom Counters dashboard panel includes a drop-down list to allow you to select from the available counters. If you delete all counters, the panel does not return to the default title and continues to display one of the counter names.
Resources
Disk Filter Columns does not work on a blank chart
The Filter Columns selection does not work in the Resources > Disk view if you receive a blank chart due to your WMI credentials being invalid.
Alerts
OS Disk Time (Percent) and OS Disk Time Per Disk (Percent) alerts may not trigger for some users
Users with Windows Server 2008 SP1 and SQL Server 2000 SP4, and who select direct WMI collection for their OS metrics may experience an issue preventing OS Disk Time (Percent) and OS Disk Time Per Disk (Percent) alerts from triggering. If this issue occurs, switch to using OLE automation.
Virtualization-related alerts occasionally raise more than once
In some circumstances, SQL Diagnostic Manager may repeatedly raise virtualization-related alerts when there is no change in the status.
Custom Counters
SQL Diagnostic Manager does not automatically add unassociated custom counters to an alert template created from an instance
If you use alert templates and create a custom counter, SQL Diagnostic Manager automatically adds the new counter to your existing alert templates. However, if you create a custom counter not associated with an instance, and then create an alert template based on the alert configuration of one of your monitored instances, SQL Diagnostic Manager does not add the new counter to your alert template nor can you manually add the counter.
To avoid this issue, add the missing custom counter to any SQL Server instance, create an alert template from that instance, and then clear any undesired custom counters from that instance.
SQLdm Mobile
SQLdm Mobile My Servers view filter does not work
The filter on this view will consistently display the message, “You have no favored or followed servers or the servers list has not been cached yet,” regardless of the filter option you choose. This issue occurs even when you are following servers or have marked servers as favorites.
