Notes

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 Utiliser des objets SQL Server.

Exemples

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]
   }
}
