Storperf Reporting Module
==========================
About this project
=====================
* This project aims to create a series of graphs to support the SNIA reports.
* All data for the reports can be fetched either from the OPNFV Test Results DB, or locally from StorPerf's own database of current run data.
* The report code may be stored in either the Releng repository (so it can be included in the Test Results Dashboards), or locally in StorPerf's own git repository.
* The report (generated by the reporting module) looks like the following example:
.. image:: demo_example.png
:align: center
Usage
=======
* Enter the URL for the location of the data for which you want to generate the report.
* Note: You can test the module using the testdata present in the directory ``storperf-reporting/src/static/testdata``. Instead of the URL enter the filename present in the testdata directory, eg. **local-data.json**
* After entering the URL, you are taken to the page showing the details of the all the jobs present in the data.
* Click on the *Click here to view details* to see the different block sizes for the respective job.
* Click on the block size and select the parameter for which you want to view the graph.
Graph Explanation
===================
Example of a graph generated is shown below:-
.. image:: graph_explanation.png
:align: center
**Steady State Convergence Graph**
* This graph shows the values as reported by StorPerf for the actual and average throughput.
* Also shown is the average +-10% and the slope.
* It serves to visually demonstrate the compliance to the steady state definition.
* The allowed maximum data excursion is 20% of the average (or average x 0.20)
* The allowed maximum slope excursion is 10% of the average.
* The measured data excursion is the value from range.
* The measured slope excursion is the value from range
Workflow
==========
A Flask server is used to fetch the data and is sent to the client side for formation of the graphs (Using Javascript).
Steps involved
--------------
* Step 1: Data is fetched from the OPNFV Test Results ReST API
* Step 2: The fields "report_data" and "metrics" are taken from the JSON object retrieved in the above step and sent to the client side.
* Step 3: The "report_data" is obtained by the client side and a parser written in Javascript along with Plotly.js forms the graphs.
