2. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 ARM-9 – Karlruhe, 2007-02-05 2 Deliverable DSA1.4 Title: Assessment of Production Service Status Follow up of EGEE-I deliverable DSA1.8: Assessment of Operational Service Status – Description of operational services: COD, GGUS, ESC …. From the TA (TSA1.1) As a basis for planning and monitoring improvements to the reliability and stability of the service, several deliverables (DSA1.4, DSA1.6) are proposed to assess the status of the service. These will use a set of metrics to be defined in MSA1.1 and take as a baseline the final service assessment from EGEE (DSA1.8). The metrics defined in MSA1.1will also be reported on in the quarterly reports

Grid management To co-ordinate the implementation of the above points (3.3 – 3.6) by the Regional Operations Centres (ROC), as well as to manage the relations with resource providers through negotiation of service-level agreements (SLAs), and relations with the wider Grid community through participating standards bodies.  No metrics. SLA status?  OAG activity ? –Tier1 (SC4) assessment? – gridview
