MSSQL on Windows: Tentatively-deleted rows touched/sec

Microsoft.SQLServer.Windows.CollectionRule.DBEngine.XtpCursors_TentativelyDeletedRowsTouchedSec (Rule)

Collects the Windows "Tentatively-deleted rows touched/sec" performance counter for internal XTP engine cursors.

Knowledge Base article:

Summary

The rule collects the Windows "Tentatively-deleted rows touched/sec" performance counter for internal XTP engine cursors.

The XTP Cursors performance object contains counters related to internal XTP engine cursors. Cursors are the low-level building blocks the XTP engine uses to process T-SQL queries. As such, a user does not typically have direct control over them.

Tentatively-deleted rows touched/sec - The number of expiring rows touched by cursors (on average), per second. A row is expiring if the transaction that deleted it is still active (i.e. has not yet committed or aborted.)

Overridable Parameters

Name	Description	Default Value
Enabled	Enables or disables the workflow.	Yes
Interval (seconds)	The recurring interval of time in seconds in which to run the workflow.	900
Timeout (seconds)	Specifies the time the workflow is allowed to run before being closed and marked as failed.	300
Timeout for query execution (seconds)	The workflow will fail and register an event, if the query execution takes longer than the specified period.	60
Timeout for database connection (seconds)	The workflow will fail and register an event, if it cannot access the database during the specified period.	15
