== 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?)
 
 
 
=== Latest meeting to discuss Cloud Accounting Data ===
 
 
 
A team from the Fedcloud task met on 25th July and 1st August 2013 to discuss the data received so far from the Resource Providers and where improvements should be made.  The outcome of these meetings is here: [https://oerc.basecamphq.com/projects/7732005/file/164221704/CloudAccountingMeetings-JulAug2013.pdf]
 
 
 
== Cloud Accounting Usage Record ==
 
A new version of the Cloud Accounting Usage Record should be used with a new version of SSM (Version 2.0), further information is here: [https://oerc.basecamphq.com/projects/7732005/file/149644970/New-CloudAccountingUR.pdf New Cloud Accounting Usage Record]
 
 
 
==== Previous versions ====
 
The previous version of the Cloud Accounting Usage Record is here: [https://oerc.basecamphq.com/projects/7732005/file/125408455/Current%20Version-CloudAccountingUR.pdf Previous Cloud Accounting Usage Record v.1]
 
 
 
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 ===
 
 
 
To publish records to the central Cloud Accounting Database resource providers will need to install and configure SSM 2.0 and also create messages containing records which are sent using SSM.  The information below has links to scripts for creating these messages for OpenNebula and Openstack sites.  There is also information on the installation of SSM 2.0 below.
 
 
 
===== SSM Package for publishing records =====
 
 
 
The new version of SSM (2.0) should be retrieved from here [http://apel.github.com/apel/]
 
 
 
There are versions for SL5 and SL6.
 
 
 
There are a number of changes from the previous version of SSM, including where configuration files and messages containing records are located.  We now have different destination queues;  for cloud  accounting using SSM 2.0 the destination queue to be set in /etc/apel/dns is:
 
 
 
destination: /queue/global.accounting.cloudtest.CENTRAL
 
 
 
===== 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.
 
 
 
==== Cloud Accounting Message Format for use with SSM 2.0 ====

=== OpenNebula resource providers ===
 
Records may be retrieved from OpenNebula databases using the cloudacc script from [https://github.com/EGI-FCTF/opennebula-cloudacc EGI-FCTF/opennebula-cloudacc] which creates a file in the message format which can be sent using the SSM 2.0.
 
 
 
Current stable version: 3.8.3

=== Openstack resource providers ===
 
===== Steps =====
 
# Install the software
 
# Check out the doc (man osssmrc)
 
# Edit /etc/osssmrc
