    var monitor = new MySqlMonitor() { IsActive = true };
    monitor.SendCallStack = false;
    monitor.Filter = Devart.Common.MonitorEventFilter.OpenConnection | Devart.Common.MonitorEventFilter.Execute;
    Dim monitor = New MySqlMonitor() With {
    .IsActive = True
    }
    monitor.SendCallStack = False
    monitor.Filter = Devart.Common.MonitorEventFilter.OpenConnection Or Devart.Common.MonitorEventFilter.Execute
