OLE DB Data Source Template

Updated: November 1, 2013

Applies To: System Center 2012 - Operations Manager, System Center 2012 R2 Operations Manager, System Center 2012 SP1 - Operations Manager

OLE DB (Object Linking and Embedding Database) is a Microsoft technology for accessing a variety of data sources by using a common method to connect to different databases such as Microsoft SQL Server.

The OLE DB Data Source template lets you monitor the availability and performance of any database that can be accessed with OLE DB. One or more watcher nodes connect to the database to verify its availability and test its performance. The watcher nodes can test the connection to the database or measure the time taken to perform a particular query.

The database can reside on any computer whether it has an agent for Operations Manager installed or not, but it must be accessible from the watcher nodes. Each watcher node must have an Operations Manager agent installed.

Scenarios

Use the OLE DB Data Source template in scenarios where applications rely on a database. You can either define a single watcher node to ensure that the database is accessible and responds to requests, or you can define each application server as a watcher node. The monitors that the template creates attempt to connect to the database from each location at the defined interval, and verify that each watcher node can connect successfully. In addition to validating the health of the database itself, any network connections and other required features between the watcher node and the database are also validated. You can use any number of watcher nodes, but it is typically most useful to select a sample that represents different environment or network segments.

Monitoring Performed by OLE DB Data Source Template

Depending on your selections in the OLE DB Data Source Template wizard, the monitoring performed by the created monitors and rules can include any of the following settings.

 

Type Description Enabled?

Monitors

Success of the database connection or query

Enabled by default.

Time to connect to database

Enabled if specified in wizard.

Time to complete query

Enabled if specified in the wizard and the query is provided.

Time to fetch results of query

Enabled if specified in the wizard and the query is provided.

Collection Rules

Collection of time to connect to the database

Enabled by default.

Collection of time to complete the query

Always enabled if the query is provided.

Collection of time to fetch results of query

Always enabled if the query is provided.

Viewing Monitoring Data

All data collected by the OLE DB Data Source template is available in the OLE DB Data Source State view located in the Synthetic Transaction folder. In this view, an object represents each of the watcher nodes. The state of each object represents the worst state of the set of database monitors that are running on that node. If one or more of the nodes is shown with an error while at least one other node is healthy, it could indicate a problem with that particular node accessing the database, a network issue. If all of the nodes are unhealthy, it could indicate a problem with the database itself.

You can view the state of the individual database monitors by opening the Operations Manager Health Explorer for each object. You can view performance data by opening the Performance view for each of these objects.

Wizard Options

When you run the OLE DB Data Source template, you have to provide values for options in the following tables. Each table represents a single page in the wizard.

General Properties

The following options are available on the General Options page of the wizard.

 

Option Description

Name

The name used for the monitoring wizard. This name is displayed in the Operations console in the OLE DB Data Source State view.

Description

Optional description of the monitor.

Management Pack

Management pack to store the classes, monitors, and rules that the template created.

For more information about management packs, see Selecting a Management Pack File.

Connection String

The following options are available on the Connection String page of the wizard.

 

Option Description

Connection string

The connection string to connect to the database. A connection string contains the properties required to locate and connect to the database. It contains such information as the server that is hosting the database, the database name, and the type of authentication to perform. You can type a connection string or build a connection string in a dialog box by clicking Build.

For more detailed information about connection strings, see Connection String Syntax.

Query to execute

Optional query after the connection to the database has been made. If no query is provided, the monitor only attempts to connect to the database.

Query time-out

If a query is provided, this option specifies the maximum number of seconds that the query can take before it times out. You must set the Query Time-out value.

Query Performance

The following options are available on the Query Performance page of the wizard.

 

Option Description

Connection time in milliseconds

If selected, the values Error Threshold and Warning Threshold provide the number of milliseconds for the connection when the monitor enters that state and an alert is generated. If not selected, the connection time is not monitored.

Query time in milliseconds

If selected, the values Error Threshold and Warning Threshold define the number of milliseconds the query can run before the monitor enters that state and generates an alert. If not selected, the time to run the query is not monitored. If a query is not provided, this option is not available.

Fetch time in milliseconds

If selected, the values Error Threshold and Warning Threshold define the number of milliseconds to retrieve the results of the query before the monitor enters that state and generates an alert. If not selected, the time to retrieve the results of the query is not monitored. If a query is not provided, this option is not available.

Watcher Nodes

The following options are available on the Watcher Nodes page of the wizard.

 

Option Description

Select one or more agent-managed computers

Specify one or more agent-managed computers to run the monitor. For more information, see Watcher Nodes.

Run this query every

The frequency to attempt the connection to the database and run the query, if specified.

Security Considerations

The OLE DB Data Source template creates two Run As profiles. The name for each of these profiles starts with the name that you provided in the template and is followed by “Simple Authentication Profile” and “Synthetic Transaction Profile”. If no Run As account is added to either of these profiles, the Default Action Account for each watcher node is used to connect the database and run the query. If the Default Action Account does not have access to the database that is being monitored, the connection fails. You can specify either integrated security or simple authentication by creating a Run As account and adding it to the appropriate Run As profile that the OLE DB Data Source template created.

When you run the OLE DB Data Source template, it creates two Run As profiles. The name for each starts with the Name that you provided when you ran the template. The OLE DB Synthetic Transaction Profile is used when you want to use integrated security for the database connection. The OLE DB Simple Authentication Profile is used when you want to use simple authentication for the database connection.

Integrated Security

Integrated security lets you connect to the database by using credentials stored in Active Directory Domain Services. To connect the watcher nodes to the database by using integrated security, create a Run As account with Windows as the Account type and the credentials for the appropriate user account. Then add this Run As profile to the OLE DB Synthetic Transaction Profile.

Simple Authentication

Simple authentication lets you connect to the database by using a simple name and password. For a SQL Server database, this simple authentication could be used for SQL Server authentication. To have the watcher nodes connect to the database by using simple authentication, create a Run As account with Simple Authentication as the Account type and the credentials for the appropriate user account. Then add this Run As profile to the OLE DB Simple Authentication Profile. When you specify the connection string for the template, select the Use Simple Authentication RunAs Profile created for this OLE DB data source transaction check box. This adds variables to the connection string for the user name and password that you specified in the Run As account.

Creating and Modifying OLE DB Data Source Templates
