Valeur de propriété

A String value that specifies the performance condition.

Notes

When setting the PerformanceCondition property, the value requires the following syntax:

ObjectName|CounterName|Instance|ComparisonOp|CompValue

Part	Description
ObjectName	Name of a monitored Microsoft SQL Server object
CounterName	Name of a counter exposed by the object
Instance	Name of an instance of the counter
ComparisonOp	One of the relational operators =, >, or <
CompValue	Numeric value compared

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.

Exemple

For example, to create an alert raised when the average wait time for an extent lock rises above 1 second (1,000 milliseconds), set the PerformanceCondition property using the string:

SQLServer:Locks|Average Wait Time (ms)|Extent|>|1000

Many SQL Server Performance Monitor counters do not define instance parameters. When an instance parameter is not applicable, indicate that no instance is selected using an empty Instance part in the value string, as in:

SQLServer:Access Methods|Page Splits/sec||>|50
