Erlang Diameter Credit Control Client

This repository contains an example OTP DCCA application client built in Erlang. It's used as a companion to the DCCA-server-OTP application.

To run the commands, you need rebar3 that can be either installed into the system (for example using Brew on Mac) or downloaded into the current application diretory (with execution permission).

To build the modules and diameter dictionaries, use rebar:

rebar3 compile

or

make

To start the module use (the DCCA server must be up already):

make shell
dccaclient:test().  # This will use a simulated event

on Windows, use make wshell.

Testing

To test the client, use the server module from dcca-server-OTP.

The accepted commands are:

Test DCCA with a simulated event

dccaclient:test().

Simulate with your own values

dccaclient:charge_event({gprs, {MSISDN, IMSI, ServiceId, RatingGroup, VolumeBytes, TimeToWait}}).

ex:
dccaclient:charge_event({gprs, {"5511985231234", "72412345678912", 1, 100, 1000000, 1}}).

To exit, type Ctrl+G to call the Erlang shell followed by the command "q".
