== Plan ==
To account for resource usage across multiple resource providers we need to define:
 
# the elements to be accounted for and how accounting data may be gathered. (This relates to the statement  “Resource providers agree and follow the same rules for accounting the resource usage”.)
# how accounting data will be published
# what is required from this data (for VM users, Resource Providers, VO Managers, others?)
 
== Cloud Accounting Usage Record ==
The current version of the Cloud Accounting Usage Record is here: [https://oerc.basecamphq.com/projects/7732005/file/125408455/Current%20Version-CloudAccountingUR.pdf Draft Cloud Accounting Usage Record]
 
 
==== Previous versions ====
This draft schema attempts to map the Cloud Accounting Usage Record fields to fields used by Venus-C and OpenNebula.

==== Compute Accounting Record ====
To help define what we will account for the existing [https://twiki.cern.ch/twiki/pub/EMI/ComputeAccounting/CAR-EMI-tech-doc-0.8.doc Compute Accounting Record] has been used.
 
== Publishing Cloud Accounting Records ==
 
 
==== Cloud Accounting System ====
The software and technology choices for the new APEL system (which receives compute accounting records) will be used to provide a ‘testbed’ so that the resource providers can send records to a Cloud Accounting System at STFC.  The software is written in Python and the data is stored in a MySQL database, the component parts of the system are:
 
# SSM
# Record loader
# MySQL Database
 
More detail available in the Cloud Accounting System document here:
[https://oerc.basecamphq.com/projects/7732005/file/111685266/The%20Cloud%20Accounting%20System.pdf Cloud Accounting System]
 
==== Publishing Records ====
===== OpenNebula resource providers =====
Records may be retrieved from OpenNebula databases using this script [https://oerc.basecamphq.com/projects/7732005/file/115574771/cloudacc.txt Version 1]  or this later version [https://oerc.basecamphq.com/projects/7732005/file/116598263/cloudacc-v2.sh Version 2] which creates a file in the message format which can be sent using the SSM.
===== Openstack resource providers =====
# Install the software
# Check out the doc (man osssmrc)
# Edit /etc/osssmrc and activate the osssm service
The rpm sources are located on the '''[https://github.com/EGI-FCTF/osssm EGI-FCTF github]'''.

* '''[ftp://ftp.in2p3.fr/ccin2p3/egi-acct-osdriver/ binary packages for RHEL based systems]'''

* '''[ftp://ftp.in2p3.fr/ccin2p3/egi-acct-osdriver/changelog Changelog]'''
 
===== SSM Package for publishing records =====
 
A new version of the SSM client package can be retrieved from here: [https://oerc.basecamphq.com/projects/7732005/file/134129656/clientssm-1.2-2.noarch.rpm] It requires configuration and the short description of how to install and setup the new version is here: [https://oerc.basecamphq.com/projects/7732005/file/134129793/SSMClient-setup2.pdf]
 
===== Terminology: =====
 
* A message is one file which is sent and received by the SSM. Usually a message will contain a number of records (eg 1000)
* A record corresponds to one row in the database. It contains a number of key-value pairs as specified in the table below
* The header in each message tells the server which type of records are in that message. You need one header per message, so one header per file.

==== Other work on providing OpenNebula Accounting Records ====
 
Contact made with "VENUS" project developers who have developed a system for extracting accounting data.  Detail on the Cloud Accounting System (above) provided to them, requested more detail on their implementation.
