Make HEP network setting configurable

[hamidrhashmi]

I am trying to send freeswitch CDRs as HEP Log to Homer. But I am unable to set HEP SRC IP and SRC Port with respect to IPs in the CDRs so That I can see Log Correclty in the flow.

Pastash Configuration

input {
      file {
        path => "/home/hrhashmi/FREESWITCH/var/log/freeswitch/cdr-csv/Master.csv"
      }
    }
 filter {
   csv {
    headers => ['caller_id_name', 'caller_id_number', 'source_ip', 'source_port', 'destination_number', 'context', 'start_stamp', 'answer_stamp', 'end_stamp', 'duration', 'billsec', 'hangup_cause', 'uuid', 'bleg_uuid', 'accountcode','codec','bleg_codec']
 }
  compute_field {
    field => correlation_id
    value => "#{uuid}"
  }
  compute_field {
    field => s_ip
    value => "#{source_ip}"
  }
  compute_field {
    field => s_port
    value => "#{source_port}"
  }
}
    output {
      hep {
        host => debian10.hbvoice.local
        port => 9063
        hep_id => 2022
        hep_type => 100
        hep_cid => '#{correlation_id}'
        hep_protocol => 17
        src_ip => '#{s_ip}'
        src_port => '#{s_port}'
        dst_ip => 192.168.0.167
      }
      stdout{}
    }

Pasttash Logs (it does not print hep packet.)

I can see a comment here which says that the Network part is to be Done.

s_ip and s_port will have no effect. The correct fields to force IPs in the HEP output are srcIp, srcPort, dstIp, dstPort

        // Build HEP3 w/ null network parameters
        hep_proto.srcIp = data.srcIp || this.src_ip;
        hep_proto.dstIp = data.dstIp || this.dst_ip;
        hep_proto.srcPort = data.srcPort || this.src_port;
        hep_proto.dstPort = data.dstPort || this.dst_port;
