Deploying PingIntelligence policies in Akana API gateway is divided into three parts:

  • Adding an input script (config.js).
  • Adding PingIntelligence policy and applying the policy to APIs.
  • Adding RetainerHeader policy and applying the policy to APIs.

    Complete the following steps to download and extract the PingIntelligence policy:
    1. Download the PingIntelligence policy.
    2. Extract the policies by using the following command.

      # tar –zxvf <<file name>>

      For example,

      # tar –zxvf pi-api-akana-policy-4.1.1.tar.gz

  2. Click Add Script.
  3. Enter Script Name and Script Description, and click Next.

  4. Select JavaScript as Language from the list.
  5. Copy the contents of config.js script provided by PingIntelligence and paste them into the Source.

  6. Substitute the values of ‘Service_QName’, ‘Interface_Name’, and ‘Operation_Name’ that were captured in Capture ASE details step.This needs to be performed for both primary and secondary ASE nodes. The below table lists the variables in config.js that needs to be populated.
    Variable Purpose

    primary_ase_service Service QName for primary ASE.

    secondary_ase_request_operation Operation Name for posting Request Metadata in secondary ASE.
    secondary_ase_response_operation Operation Name for posting Response Metadata in secondary ASE.

    Here is a sample substitution snippet for reference: 

    var ase_token = "ASE-Token-123";
/*Primary ASE Configuration*/
var primary_ase_service = "{pi-as-ase-primary_0.0.0}svc_314492f1-ecdc-4184-93a0-57ee2258154b.smshargi.sandbox";
var primary_ase_interface = "{pi-as-ase-primary_0.0.0}pi-as-ase-primary_PortType_0";
var primary_ase_request_operation = "postRequestMetadata";
var primary_ase_response_operation = "postResponseMetadata";
/************************/
/*Secondary ASE Configuration*/
var secondry_ase_service = "{pi-as-ase-primary_0.0.0}svc_314492f1-ecdc-4184-93a0-57ee2258154b.smshargi.sandbox";
var secondary_ase_interface = "{pi-as-ase-primary_0.0.0}pi-as-ase-primary_PortType_0";
var secondary_ase_request_operation = "postRequestMetadata";
