How to enter / edit connection details
Use a Spotlight Client to enter / edit connection details.
From the Spotlight Client
- Click Configure | Connections.
- Double click Add new connection.
- Fill in the connection details.
Specify the connect string used to link to the SQL Server (that is, the Server Name, Server Instance Name, or IP address).
Specify the authentication for Spotlight to use to connect to the SQL Server instance.
Select Windows Authentication (using Diagnostic Server credentials) to use the Windows user configured to run the Spotlight Diagnostic Server. Ensure this account is trusted by the SQL Server. When using Windows authentication to connect to a SQL Server, and that SQL server is in a different domain to the Spotlight Diagnostic Server, the domain the SQL Server is in must trust the domain the Spotlight Diagnostic Server is in.
Alternatively, fill in the Database User and Password fields. Ensure the database user has sufficient account permissions to retrieve performance data from the SQL Server instance and host by WMI. Typically the account will be a member of the sysadmin server role. It could be a SQL Server login (such as ‘sa’). If this is not feasible in your environment, see How to grant SQL Server account permissions to a trusted user.
The connection will fail if the account permissions are insufficient to allow Spotlight to collect the data it needs.
Read Only Intent
Select this option if the SQL Server instance hosts a secondary replica of an Availability Group and for this secondary replica ApplicationIntent=ReadOnly. Failure to select this option when required will result in some data not being collected for the secondary replica; this will be most noticeable on the SQL Server | Databases drilldown.
Use Extended Events
The Spotlight Diagnostic Server will use Extended Events to collect data from the SQL Server instance. The data is used by:
- SQL Server | Workload Analysis Drilldown
- SQL Server | Wait Events Drilldown
- Deadlock checks: SQL Server | SQL Activity Drilldown, Locks - Deadlocks Alarm.
If you select to use Extended Events (following a period of time when the use of Extended Events was deselected) the SQL Server | Workload Analysis drilldown and SQL Server | Wait Events drilldown may take a few minutes to repopulate with data.
The Spotlight Diagnostic Server will use SQL Server Trace to collect data for deadlock checks. The Spotlight Diagnostic Server will NOT collect data for the SQL Server | Workload Analysis drilldown and SQL Server | Wait Events drilldown.
If you set this value after the connection to the SQL Server is established then the change will not show up immediately on the user interface as the Workload Analysis drilldown and Wait Events drilldown will continue to show historical data till no data is available.
Obscure string literals in SQL text and parameters in query plans
Dummy text replaces string literals in all displays of the SQL Statement and Query Plan. This protects privacy information that may be contained in those literals.
Large numbers (greater than 99,999,999) are replaced with 987654321.
Large numbers and string literals in SQL Statements and Query Plans are displayed as is.
Exclude Spotlight sessions from Wait Events and Workload Analysis
When selected Spotlight sessions are excluded from the Wait Events and Workload Analysis drilldowns.
Store SQL text and query plans in playback
When Selected, Spotlight stores SQL query statements and plans in the Playback Database for this SQL Server connection. This data will be available during playback of events and data collected in the recent past in the SQL Activity drilldown | Sessions page and the SQL Activity drilldown | Query Execution Statistics page.
Select the Windows server hosting the SQL Server.
Do not monitor
Select Do not monitor if you do not want to monitor the Windows server.
Cluster (monitor active node)
Select Cluster (monitor active node) for a Microsoft Cluster Server (MSCS).
Spotlight uses the current host node name to select the operating system connection. Therefore each Windows node in the cluster must be monitored by Spotlight. Verify each Windows node is in the list of Windows server connections.
Click Create to add a Windows server to the list. This opens Windows Server | Connection Details.
Select the alarms configuration template to apply to this connection.
Select from any of the SQL Server configuration templates that you have created through Configure Alarms or select Factory Settings Template to apply the Factory Settings shipped with Spotlight.
Test the connection
On entering / modifying connection details in the Spotlight Client, click Test to test the connection.
Connection to the Windows host
Verify the SQL Server host is in a domain. Spotlight cannot monitor a SQL Server database when the Windows host is in a workgroup.
If the SQL Server is hosted within Microsoft Cluster Server (MSCS) then ensure the Windows Server host is selected as Cluster (monitor active node). Spotlight uses the current host node name to select the operating system connection. Therefore each Windows node in the cluster must be monitored by Spotlight. Verify each Windows node is in the list of Windows server connections.
The Spotlight Diagnostic Server uses WMI queries to retrieve performance counter information from the Windows server host. Verify WMI is working and returns data properly.
Verify TCP port 135 is open on the Windows server host.
Connection to the SQL Server instance
If Spotlight cannot connect to the SQL Server instance then use another tool such as Microsoft’s SQL Server Management Studio or sqlcmd to connect to the SQL Server instance. Is the issue with Spotlight’s ability to connect to the SQL Server instance or with any any/every tool’s ability to connect to the SQL Server instance?
Ensure ports are open as outlined in the Microsoft KBase article that describes SQL Server firewall connectivity issues: http://msdn.microsoft.com/en-us/library/cc646023.aspx.
If Spotlight cannot connect to the SQL Server instance you may need to upgrade Microsoft Data Access Components (MDAC) on the Spotlight Client host AND the Spotlight Diagnostic Server host. More information is available from the Microsoft Download Center (search for MDAC).
Check the Spotlight Enterprise Release Notes for known issues.
