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