Property Value
A String value that specifies the performance condition.
Remarks
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 |
Example
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
