Namespace: Microsoft.SqlServer.Management.Smo.Agent
Assembly: Microsoft.SqlServer.Smo (in microsoft.sqlserver.smo.dll)

Syntax

'Declaration
Public Property PerformanceCondition As String

public string PerformanceCondition { get; set; }

public:
property String^ PerformanceCondition {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_PerformanceCondition ()

/** @property */
public void set_PerformanceCondition (String value)

public function get PerformanceCondition () : String

public function set PerformanceCondition (value : String)

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

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

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
