Recording Access Audit Events in JSON

This section describes how to record access audit events with a JSON audit event handler. For information about configuring the JSON event handler, see "JsonAuditEventHandler".

Record Audit Events With a JSON Audit Event Handler
  1. Add the following route to IG:

    $HOME/.openig/config/routes/30-json.json
    %appdata%\OpenIG\config\routes\30-json.json
    {
      "name": "30-json",
      "baseURI": "http://app.example.com:8081",
      "condition": "${matches(request.uri.path, '^/home/json-audit')}",
      "heap": [
        {
          "name": "AuditService",
          "type": "AuditService",
          "config": {
            "eventHandlers": [
              {
                "class": "org.forgerock.audit.handlers.json.JsonAuditEventHandler",
                "config": {
                  "name": "json",
                  "logDirectory": "/tmp/logs",
                  "topics": [
                    "access"
                  ],
                  "buffering": {
                    "maxSize": 100000,
                    "writeInterval": "100 ms"
                  },
                  "rotationRetentionCheckInterval": "1 m"
                }
              }
            ]
          }
        }
      ],
      "auditService": "AuditService",
      "handler": "ReverseProxyHandler"
    }

    Notice the following features of the route:

    • The route calls an audit service configuration for publishing log messages to the JSON file, /tmp/audit/access.audit.json. When a request matches /home/json-audit, a single line per audit event is logged to the JSON file.

    • The route uses the ForgeRockClientHandler as its handler, to send the X-ForgeRock-TransactionId header with its requests to external services.

  2. Go to http://openig.example.com:8080/home/json-audit.

    The home page of the sample application is displayed and the file /tmp/logs/access.audit.json is created or updated with a message. The following example message is formatted for easy reading, but it is produced as a single line for each event:

    {
      "_id": "830...-41",
      "timestamp": "2019-...540Z",
      "eventName": "OPENIG-HTTP-ACCESS",
      "transactionId": "830...-40",
      "client": {
        "ip": "0:0:0:0:0:0:0:1",
        "port": 51666
      },
      "server": {
        "ip": "0:0:0:0:0:0:0:1",
        "port": 8080
      },
      "http": {
        "request": {
          "secure": false,
          "method": "GET",
          "path": "http://openig.example.com:8080/home/json-audit",
          "headers": {
            "accept": ["text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"],
            "host": ["openig.example.com:8080"],
            "user-agent": ["Mozilla/5.0 ... Firefox/66.0"]
          }
        }
      },
      "response": {
        "status": "SUCCESSFUL",
        "statusCode": "200",
        "elapsedTime": 212,
        "elapsedTimeUnits": "MILLISECONDS"
      }
    }
