Tools and Technologies used • Python 2. 4. 3 • Django-1. 1. 1(high-level Python Web framework ) • Django-piston-0. 2. 2(Django mini-framework for creating APIs)

List of APIs provided by New SAM(ATP, MDDB, MRS) • GROUP(site groupings defined by various vo's in ATP ) Parameter: vo(optional, multiple) URL: http: //<hostname>/mrs/api/group • SITE GROUP(sites present in a site group defined by various vo's in ATP ) Parameter: vo(mandatory, single) sitegroup(optional, multiple) URL: http: //<hostname>/mrs/api/site_group • SERVICE GROUP(service flavours present in a service group defined by various vo's in ATP) Parameter: vo(mandatory, single), group(optional, multiple) URL: http: //<hostname>/mrs/api/service_group • METRIC NAME(metrics present in different profiles defined by various vo's in MDDB ) Parameter: vo(mandatory, single) profile, service, flavour, testname(optional, multiple) URL: http: //<hostname>/mrs/api/metric_name • HISTORY OF SERVICE METRIC STATUS(history result of service metrics(tests) present in a profile and executed in a particular sitegroup by the vo from the MRS ) Parameter: vo, startdate, enddate, timerange(mandatory, single) sitegroup, profile, flavour, host(optional, multiple) URL: http: //<hostname>/mrs/api/metric_result

List of APIs provided by New SAM(ATP, MDDB, MRS) • DETAIL RESULT OF SERVICE METRIC (detail log of the Service Metric(test) executed by the vo from MRS ) Parameter: vo, hostname, metric, timestamp(mandatory, single) URL: http: //<hostname>/mrs/api/metric_detail • SERVICE-END-POINT PRESENT IN THE SITE (different service-end-points present in a site from ATP ) Parameter: vo(mandatory, single) sitegroup, site, flavour, service(optional, multiple) URL: http: //<hostname>/mrs/api/hostname • ADJACENT HOST OF GIVEN HOST (adjacent host for a given host present in a site from ATP ) Parameter: vo(mandatory, single) site, flavour, host(optional, multiple) URL: http: //<hostname>/mrs/api/adjacent_host • SERVICE METRIC STATUS (possible status a service metric(Test) may have after execution from MRS ) Parameter: This query doesn’t accept any parameter. URL: http: //<hostname>/mrs/api/servicemetric_status

List of APIs provided by New SAM(ATP, MDDB, MRS) • VO NAME(VO Names defined in ATP ) Parameter: This query doesn’t accept any parameter. URL: http: //<hostname>/mrs/api/vo_name • SITE NAME (site names present in ATP ) Parameter: site_type(optional, multiple) site_status(optional, single) URL: http: //<hostname>/mrs/api/site_name • SERVICE TYPES (Service Types defined in ATP ) Parameter: This query doesnot accept any parameter. URL: http: //<hostname>/mrs/api/service_type • SERVICE TYPE RUNNING IN SERVICE-END-POINT OR SITES (Service types defined in each service-endpoint or Sites from ATP) Parameter: serviceendpoint, sitename(optional, multiple) URL: http: //<hostname>/mrs/api/servicetype_per_service_endpoint • STATUS, TIMESTAMPS AND DETAILS OF SERVICE-ENDPOINT AND SERVICE METRICS EXECUTED BY A CERTAIN VO (latest timestamps(execution time) of all Service Metrics executed by certain VO in any Service-endpoint and Site) Parameter: vo, site, flavour, infrastructure(mandatory and single) URL: http: //<hostname>/mrs/api/service_endpoint_status

What needs to be implemented? • Availability results of the sites, service, etc. • Reliability results of the sites, service, etc. • Fine grain access control mechanism for the implemented APIs via django-piston.
