About the monitoring options

Use the detail monitoring capability of the VCS agent forSQL Server to monitor the status of a SQL Server instance.

The agent provides the following levels of application monitoring:

  • Basic monitoring queries the Windows Service Control Manager (SCM) to verify whether the configured SQL Server services are continuously active.

  • Detail monitoring queries the databases to verify their availability.

Table: Methods of configuring detail monitoring

Method

Description

Database list-based monitoring

The agent monitors only the list of databases that are specified in the its DBList attribute. It uses Microsoft ActiveX Data Objects (ADO) to establish a connection with the selected databases to verify the health of those databases.

  • If the connection is successful, the agent considers the SQL Server instance as available.

  • If the connection fails, the SQL Server instance is considered not available. Then, if the FaultOnDMFailure attribute is configured, the service group fails over to the failover nodes.

Script-based detail monitoring

The agent uses a script to monitor the status of the SQL Server instance.

  • If the script is successfully executed during monitoring, the agent considers the instance available.

  • If the execution fails, the instance is considered not available. Then, if the FaultOnDMFailure attribute is configured, the service group fails over to the failover nodes.

A sample SQL script is provided with the agent for this purpose. Customize the script to meet your configuration requirements, or use your own script, which can be placed at any other location.

The script is located at: %VCS_HOME%\bin\SQLServer\sample_script.sql

where, %VCS_HOME% points to the default installation directory, typically: C:\Program Files\Veritas\Cluster Server.

Use a separate script for each SQL Server service group in the cluster and place it on every node in the service group.

You can enable and configure detail monitoring by running the SQL Server Agent Configuration Wizard.

See About configuring the SQL Server service group.

Note:

If you provide input for both types of detail monitoring, database list-based monitoring takes precedence and script-based monitoring is not performed.

Note:

The VCS agent monitors the computer context of the services that are configured for high availability. If the SQL Server service is not started in the virtual server context - that is, outside VCS - the resource goes into the UNKNOWN state. To avoid this situation, ensure that you start all the SQL Server-related services from within VCS.
