Summary

The rule collects the Linux "XTP Controller DLC Latency/Fetch" performance counter for SQL Database with Memory-Optimized tables.

This defines a Database manager object for SQL Server

XTP Controller DLC Latency/Fetch - Average latency in microseconds between log blocks entering the Direct Log Consumer and being retrieved by the XTP controller, per second.

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
