---+ Automation of Data Validation

%TOC%

---++ Introduction

To assist with the validation of the accounting data, a script has been written to download the data from the two sources, calculate their ratios and publish the results on the Site Status Board. The script is set to be executed automatically on a monthly basis. Extra emphasis was given on the visualisation of the data.

This work was done by Dimitrios Christidis as part of the 2016 CERN opelab Summer Student Programme, under the supervision of Julia Andreeva.
The full report will be available on ZENODO.

---++ Information for users

At the time of writing, only ATLAS and CMS provide an interface to acquire the accounting data on demand.
A limited set of data for ALICE and LHCb has been published manually.

---+++ Main view

The [[http://wlcg-mon-dev.cern.ch/dashboard/request.py/siteview#currentView=ACCOUNTING_VALIDATION][Accounting Validation]] view shows the latest data in a table format.
The data is grouped by experiment, then by metric.

---+++ Graphs

The true usefulness of the Site Status Board comes from the ability to visualise the data over time.
Click on one of the *Ratio* metrics on the table header.
This will take you to the Site View for the requested metric.
Specify the desired *Time Period* and *Site Selection*, then press *Refresh*.

---++++ Colour coding

The colour reflects the distance of a particular ratio from 100%.
As the distance grows, the colour changes from green to yellow and finally to red.

Three thresholds are defined to specify which colour to choose.
To allow for more flexibility, they are set on a per-experiment basis.
The values that are currently used are shown below.

| *Experiment* | *Green* | *Yellow* | *Red*  |
| ALICE        | 10.0    | 30.0     | 50.0   |
| ATLAS        | 10.0    | 30.0     | 50.0   |
| CMS          | 25.0    | 50.0     | 75.0   |
| LHCb         | 20.0    | 40.0     | 60.0   |

*Table 1:* Colour-coding thresholds, as of 2016-10-17.

---+++ Raw data

Clicking anywhere on the graph will display a JSON file.
The value of the =Status= key is the raw data for that particular site and month, separated by commas.
The numbers are:
_HS06 Experiment_, _HS06 Site_, _HS06 Ratio_, _Raw Experiment_, _Raw Site_ and _Raw Ratio_.
