语法

声明
Public Function EnumPerformanceCounters ( _
    objectName As String, _
    counterName As String _
) As DataTable
用法
Dim instance As Server 
Dim objectName As String 
Dim counterName As String 
Dim returnValue As DataTable 

returnValue = instance.EnumPerformanceCounters(objectName, _
    counterName)

public DataTable EnumPerformanceCounters(
    string objectName,
    string counterName
)

public:
DataTable^ EnumPerformanceCounters(
    String^ objectName, 
    String^ counterName
)

member EnumPerformanceCounters : 
        objectName:string * 
        counterName:string -> DataTable

public function EnumPerformanceCounters(
    objectName : String, 
    counterName : String
) : DataTable

参数

objectName
类型：System.String
A String value that specifies the object on which to limit the results.

counterName
类型：System.String
A String value that specifies the counter name on which to limit the results.

返回值

类型：System.Data.DataTable
A DataTable object value that contains a list of performance counters supported by the instance of SQL Server. The table describes the different columns of the returned DataTable.

Column	Data type	Description
ObjectName	String	The name of the performance counter object. The SqlServer.ExecStatistics object, for example.
CounterName	String	The name of the performance counter. The Distributed Query counter, for example.
InstanceName	String	The name of the measurement to be taken. The Exec started per second instance, for example.

注释

This method enumerates all the performance counters available in SQL Server that you could use to create a performance alert. You can also see the performance counters listed in 使用 SQL Server 对象.

示例

Server srv = new Server("(local)");

DataTable d = srv.EnumPerformanceCounters("SqlServer:CLR", "CLR Execution");
foreach (DataRow r in d.Rows)
{
   Console.WriteLine("============================================");
   foreach(DataColumn c in d.Columns)
   {
      Console.WriteLine(c.ColumnName + " = " + r[c].ToString());
   }
}

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")

$d = $srv.EnumPerformanceCounters("SqlServer:CLR", "CLR Execution")
foreach ($r in $d.Rows)
{
   Write-Host "============================================"
   Foreach ($c in $d.Columns)
   {
      Write-Host $c.ColumnName "=" $r[$c]
   }
}
