The option can be enabled in two ways:

1. Default profile: global configuration on the device, connected as a service without specifying a profile.
2. Named profile: connected as a service with the name of the profile.

Enable the configuration parameter in /etc/dpi/fastdpi.conf for the default profile without a named one:

ntf_server=192.168.0.18/ntf

Here 192.168.0.18/ntf - is the name or the address of the server¹⁾ that hosts information page.

After the parameter is added, you have to restart the service:

service fastdpi restart

In this case management is carried out through connecting service 6 without specifying a profile:

fdpi_ctrl load --service 6 --ip 192.168.0.1
fdpi_ctrl load --service 6 --login user01

To work with a named profile, you do not need to specify the ntf_server parameter. The configuration is described in the service management section.
The maximum number of profiles for notification is set by the configuration parameter in /etc/dpi/fastdpi.conf

max_profiles_ntf=65535

Here 65535 is a default value and the upper limit.

Service status change (automatic shutdown) is recorded in the log, which is enabled by the setting

ajb_save_chnprg=1

For this log you can configure the following parameters (in the example the default value is specified):

ajb_chnprg_path=/var/dump/dpi #место размещения файлов с записью
ajb_chnprg_fsize=1073741824 #максимальный размер лога
ajb_chnprg_ftimeout=10 #периодичность записи в минутах
ajb_chnprg_bufsize=32768 #размер внутреннего накопительного буфера
ajb_save_chnprg_format=ts:prg:ipsrc #формат записи где ts - временная метка, prg - id активных в данных момент сервисов, ipsrc - IP адрес источника запроса (абонента)

Changes of service status is also recorded in the clickstream in the prg field.
