sys.dm_os_cluster_properties (Transact-SQL)

Returns one row with the current settings for the SQL Server cluster resource properties identified in this topic. No data is returned if this view is run on a stand-alone instance of SQL Server.

These properties are used to set the values that affect failure detection, failure response time, and the logging for monitoring the health status of the SQL Server failover cluster instance.

Applies to: SQL Server (SQL Server 2012 through current version).

Data Type

Description

VerboseLogging

bigint

The logging level for the SQL Server failover cluster. Verbose logging can be turned on to provide additional details in the error logs for troubleshooting. For more information, see ALTER SERVER CONFIGURATION (Transact-SQL).

  • 0 – Logging is turned off (default)

  • 1 - Errors only

  • 2 – Errors and warnings

SqlDumperDumpFlags

bigint

SQLDumper dump flags determine the type of dump files generated by SQL Server. The default setting is 0.

SqlDumperDumpPath

nvarchar(260)

The location where the SQLDumper utility generates the dump files.

SqlDumperDumpTimeOut

bigint

The time-out value in milliseconds for the SQLDumper utility to generate a dump in case of a SQL Server failure. The default value is 0.

FailureConditionLevel

bigint

Sets the conditions under which the SQL Server failover cluster should fail or restart. The default value is 3. For a detailed explanation or to change the property settings, see Configure FailureConditionLevel Property Settings.

HealthCheckTimeout

bigint

The time-out value for how long the SQL Server Database Engine resource DLL should wait for the server health information before it considers the instance of SQL Server as unresponsive. The time-out value is expressed in milliseconds. Default is 60000. For more information or to change this property setting, see Configure HealthCheckTimeout Property Settings.

Requires VIEW SERVER STATE permissions on the SQL Server failover cluster instance.

The following example uses sys.dm_os_cluster_properties to return the property settings for the SQL Server failover cluster resource.

SELECT VerboseLogging, SqlDumperDumpFlags, SqlDumperDumpPath, SqlDumperDumpTimeOut, FailureConditionLevel, HealthCheckTimeout
FROM sys.dm_os_cluster_properties;
