PerformanceCondition Property
Microsoft SQL Server의 이후 버전에서는 이 기능이 제거됩니다. 새 개발 작업에서는 이 기능을 사용하지 말고, 현재 이 기능을 사용하는 응용 프로그램은 수정하십시오.
The PerformanceCondition property specifies a Microsoft Windows Performance Monitor counter, a comparison operator and value, and enables raising a Microsoft® SQL Server™ 2000 Agent alert based on system activity.
구문
object
.PerformanceCondition [=value]
Parts
- object
Expression that evaluates to an object in the Applies To list
- value
String that specifies a Windows Performance Monitor object, counter, and instance as described in Remarks
Data Type
String
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetPerformanceCondition(SQLDMO_LPBSTR pRetVal)
HRESULT SetPerformanceCondition(SQLDMO_LPCSTR NewValue)
[!참고] SQL-DMO strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.
주의
When setting the PerformanceCondition property, value uses the 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 |
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
