+# ECOMP Vendor Event Listener API Test Collector
+
+This project contains a Python application that represents a test version of 
+the ECOMP Vendor Event Listener API. For an overview of ECOMP, see the 
+[ECOMP White Paper](http://att.com/ECOMP). For an overview of the 
+ECOMP Vendor Event Listener, see the 
+[ECOMP Vendor Event Listener Library project](http://github.com/blsaws/evel-library).
+
+Developed in 2016 for AT&T by:
+ * Alok Gupta (https://github.com/ag1367)
+ * Paul Potochniak (https://github.com/pp8491)
+ * Gayathri Patrachari(https://github.com/gp2421)
+
+Current Maintainers: 
+ * Alok Gupta (https://github.com/ag1367)
+ * Paul Potochniak (https://github.com/pp8491)

+
+# Installation
+
+Clone this project, and follow the instructions in the [Test Collector User 
+Guide](./docs/test_collector_user_guide/test_collector_user_guide.md).
+
+# Use
+
+The code is documented using docstrings - start from the
+[Test Collector](./code/collector/collector.py).

+# AT&T Vendor Event Listener Service - Test Collector - User Guide
+
+Introduction
+============
+
+Background
+----------
+
+This document describes how to use the Test Collector application to simulate
+the service API described in "AT&T Service Specification, Service: 
+Vendor Event Listener Revision 2.11, 16-Sep-2016".
+
+Purpose
+-------
+
+This User Guide is intended to enable the reader to understand how
+    the Test Collector can be used to verify the operation of applications
+    supporting the Vendor Event Listener API.
+
+
+Realization
+===========
+
+The realization of the Test Collector is a Python script which acts as a
+server for the Vendor Event Listener API. It uses [jsonschema](https://pypi.python.org/pypi/jsonschema)
+in order to validate the received JSON events against AT&T's published
+schema for the API.
+
+The overall system architecture is shown in Figure 1 and comprises 
+    three key deliverables:
+
+*    The web-application itself.
+
+*    A Backend service.
+
+*    A validating test collector application.
+
+The Test Collector is described in more detail in the
+    following sections.  The other two components are described in a separate 
+    documents:
+
+*    Reference VNF User Guide
+
+*    Reference VNF Application Note
+
+Figure 1: Realization Architecture
+
+![Realization Architecture](images/architecture.png)
+
+Note that items shown in green in the diagram are existing AT&T
+    systems and do not form part of the delivery.
+
+Validating Collector
+--------------------
+
+The validating collector provides a basic test capability for
+    the Reference VNF. The application implements the Vendor Event
+    Listener API providing:
+
+-   Logging of new requests.
+
+-   Validating requests against the published schema.
+
+-   Validating the credentials provided in the request.
+
+-   Responding with a 202 Accepted for valid requests.
+
+-   Test Control endpoint allowing a test harness or user to set a pending
+    commandList, to be sent in response to the next event received.
+
+-   Responding with a 202 Accepted plus a pending commandList.
+
+-   Responding with a 401 Unauthorized error response-code and a JSON
+    exception response for failed authentication.
+
+It is intended to be used in environments where the "real" AT&T
+    Vendor Event Listener service is not available in order to test the
+    Reference VNF or, indeed, any other software which needs to send
+    events to a server.
+
+Using the Validating Collector
+==============================
+
+The test collector can be run manually, either on a Linux platform
+    or a Windows PC. It is invoked with a number of command-line
+    arguments:
+
+```
+  C:> python collector.py --config <file>
+                          --section <section>
+                          --verbose
+```
+
+Where:
+
+  -  **config** defines the path to the config file to be used.
+
+  -  **section** defines the section in the config file to be used.
+
+  -  **verbose** controls the level of logging to be generated.
+
+Wherever you chose to run the Test Collector, note that the
+    configuration of the backend service running on the VM generating
+    the events has to match so that the events generated by the backend
+    service are sent to the correct location and the Test Collector is
+    listening on the correct ports and URLs. The relevant section of the
+    Test Collector config file is:
+    
+```
+    #------------------------------------------------------------------------------
+    # Details of the Vendor Event Listener REST service.
+    #
+    # REST resources are defined with respect to a ServerRoot:
+    # ServerRoot = https://{Domain}:{Port}/{optionalRoutingPath}
+    #
+    # REST resources are of the form:
+    # * {ServerRoot}/eventListener/v{apiVersion}
+    # * {ServerRoot}/eventListener/v{apiVersion}/{topicName}
+    # * {ServerRoot}/eventListener/v{apiVersion}/eventBatch
+    # * {ServerRoot}/eventListener/v{apiVersion}/clientThrottlingState
+    #
+    # The "vel\_topic\_name" parameter is used as the "topicName" element in the path
+    # and may be empty.
+    #
+    # Note that the path, if present, should have no leading "/" but should have a
+    # training "/".
+    #------------------------------------------------------------------------------
+    vel_domain = 127.0.0.1
+    vel_port = 30000
+    vel_path = vendor_event_listener/
+    vel_username = Alice
+    vel_password = This isn't very secure!
+    vel_topic_name = example_vnf
+```
+The equivalent section of the backend service's configuration has to
+    match, or the equivalent parameters injected in the VM by the
+    OpenStack metadata service have to match.
+
+When events are sent from the web application, the results of the
+    validation will be displayed on stdout and be written to the log
+    file specified in the configuration file.
+
+For example: A Fault event failing to validate:
+
+```
+    <machine name>; - - [29/Feb/2016 10:58:28] "POST
+    /vendor_event_listener/eventListener/v1/example_vnf HTTP/1.1" 204  0

+
+Test Control Interface
+----------------------
+
+The test collector will accept any valid commandList on the Test Control interface,
+and will store it until the next event is received at the collector.
+At this point, it will send it to the event sender, and discard the pending commandList.
+
+For example, a POST of the following JSON will result in a measurement interval change
+command being sent to the sender of the next event.
+
+```
+{
+    "commandList": [
+        {
+            "command": {
+                "commandType": "measurementIntervalChange",
+                "measurementInterval": 60
+            }
+        }
+    ]
+}
+```
+
+A python script "test_control.py" provides an example of commandList injection,
+and contains various functions to generate example command lists.
+
+The test control script can be run manually, either on a Linux platform or a Windows PC.
+It is invoked with optional command-line arguments for the fqdn and port number of the 
+test collector to be controlled:
+```
+  C:> python test_control.py --fqdn 127.0.0.1 --port 30000
+```
