## Using the NotifyMonitoringExt::EventChannelFactory.

Obtain the CosNotification Service EventChannelFactory from the Name Service as you normally would. Instead of narrowing it to a CosNotifyChannelAdmin::EventChannelFactory, narrow it to a NotifyMonitoringExt::EventChannelFactory.

      CosNaming::Name name(1);
      name.length(1);
      name[0].id = CORBA::string_dup("NotifyEventChannelFactory");

      CORBA::Object_var obj = naming_context->resolve(name);

      NotifyMonitoringExt::EventChannelFactory_var notify_factory =
        NotifyMonitoringExt::EventChannelFactory::_narrow(obj.in());

You can then create named event channels using the create_named_channel method.

      CosNotification::QoSProperties initial_qos;
      CosNotification::AdminProperties initial_admin;
      CosNotifyChannelAdmin::ChannelID id;

      CosNotifyChannelAdmin::EventChannel_var ec =
        notify_factory->create_named_channel(initial_qos,
                                             initial_admin,
                                             id,
                                             "Name of Event Channel");

## Using the NotifyMonitoringExt::ConsumerAdmin.

Obtain the NotifyMonitoringExt::ConsumerAdmin as you would the CosNotifyChannelAdmin::ConsumerAdmin. However, it must then be narrowed to a NotifyMonitoringExt::ConsumerAdmin.

      CosNotifyChannelAdmin::AdminID admin_id;

      CosNotifyChannelAdmin::ConsumerAdmin_var admin =
        ec->new_for_consumers(CosNotifyChannelAdmin::OR_OP, admin_id);

      NotifyMonitoringExt::ConsumerAdmin_var madmin =
        NotifyMonitoringExt::ConsumerAdmin::_narrow(admin.in());

Once you have a NotifyMonitoringExt::ConsumerAdmin you can then create a named proxy push supplier:

      CosNotifyChannelAdmin::ProxyID proxy_id;

      CosNotifyChannelAdmin::ProxySupplier_var proxy_supplier =
        admin->obtain_named_notification_push_supplier (
                        CosNotifyChannelAdmin::STRUCTURED_EVENT,
                        proxy_id,
                        "Consumer Name");

## Using the NotifyMonitoringExt::SupplierAdmin.

Obtain the NotifyMonitoringExt::SupplierAdmin as you would the CosNotifyChannelAdmin::SupplierAdmin. However, it must then be narrowed to a NotifyMonitoringExt::SupplierAdmin.

      CosNotifyChannelAdmin::AdminID admin_id;

      CosNotifyChannelAdmin::SupplierAdmin_var admin =
        ec->new_for_suppliers(CosNotifyChannelAdmin::AND_OP, admin_id);

      NotifyMonitoringExt::SupplierAdmin_var madmin =
        NotifyMonitoringExt::SupplierAdmin::_narrow(admin.in());

Once you have a NotifyMonitoringExt::SupplierAdmin you can then create a named proxy push consumer:

      CosNotifyChannelAdmin::ProxyID proxy_id;

      CosNotifyChannelAdmin::ProxyConsumer_var proxy_consumer =
        admin->obtain_named_notification_push_consumer (
                        CosNotifyChannelAdmin::STRUCTURED_EVENT,
                        proxy_id,
                        "Supplier Name");

## Effects of using these interfaces

Using these extended interfaces allows users to link descriptive names to various objects held within the CosNotification Service. Assuming that the Notify_Service has been configured to enable the monitoring capabilities, these objects would normally be given names that are equivalent to their id upon activation.
