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

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

Examples

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
