Overview

To test the mechanism for turning your accounting into a monetary charge charging rate needs to be defined. During the pilot the numbers are not legally binding but obviously a ballpark figure would be good as it would give more realistic pilot reports.

To define the charging rate the plan is to use a new feature of GOCDB which is known as 'A Key-Value Pair Property Bag Extensiblity Mechanism'. This allows the definition of arbitrary key-value pairs for a site or any service. If a community agrees a naming scheme for the keys and semantics for the values then they have a flexible and low overhead method of adding more information about anything defined in GOCDB. For anyone interested about more details this is documented https://wiki.egi.eu/wiki/GOCDB/Release4/Development/ExtensibilityMechanism

Instructions

If you do not have access rights to change features of your site please ask the site manager or a site admin to do it for you.

  1. Go to GOCDB https://goc.egi.eu;
  2. Navigate to your site. (My Sites) at the top of the left hand sidebar.
  3. Just above the list of Services you should see a new box called 'Site Extension Properties'
  4. At the bottom of this box there is a big green plus titled 'Add Properties' – click on it
  5. This should show a window with two fields 'Property Name' and 'Property Value'
  6. For 'Property Name' insert the 'Key Name' according to your desired 'Charge Type' (see table below) e.g. P4U_Pilot_Grid_CPU
  7. For 'Property Value' insert a real number which will be interpreted as shown in the Price Calculation column in the table below. e.g. Euros per HEPSPEC06 Hour.
  8. Click the button 'Add Site Property'
  9. If you go back to the site view you will see the 'Key Name' listed. You can edit or delete it.
  10. Then add other properties from the table below as appropriate for your site.

Once you have done this we will query GOCDB to pull the values for the pilot sites and the accounting portal will join them with usage data to produce a charging report.
