Configuration

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.
For BRAS you have to use profiles named in the Radius-Accept attributes.

Default 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.

You can include a part of the path into the address. It allows using the same server for several services.

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

Named profile

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.

This is a cold parameter and requires a restart of fastdpi.

Logs

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 #location for files with recordings
ajb_chnprg_fsize=1073741824 #maximum log size
ajb_chnprg_ftimeout=10 #write interval in minutes
ajb_chnprg_bufsize=32768 #size of internal accumulation buffer
ajb_save_chnprg_format=ts:prg:ipsrc #recording format where ts - timestamp, prg - ID of currently active services, ipsrc - source IP address (subscriber)

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

In case this parameter ends by ? or &: the parameter UrlRedir is added to the formed URL. It points to a page selected by a subscriber.
