This web interface provides critical information on the availability and reliability of sites and services based on data from the Service Availability Monitoring (SAM) framework. Key features include a Latest Results View for real-time test results, a Historical View for past data, and a Service History View. The interface is programmatically designed to fetch data and visualize the topology. Future developments will include reliability metrics for historical data and configuration support for additional experiments like ATLAS and ALICE.

Introduction This web interface will provides the information on the Availability/Reliability of Sites and Services based on results of various test matrices collected from the SAM framework. This Web Interface will have following module: • Latest Results View • Historical View • Service History View
Latest Results View It is a graphical webInterface to Provides the Results of latest tests conducted on the selected services flavoursprovided by a VO • It uses a generic web programmatic interface (http://tomtools.cern.ch/confluence/display/SAM/MyEGI+Web+Services+Specification)to get the data collected by the Service Availability Monitoring Framework. • And Topology for the VO is feed through an ATP_VO_FEED. Current topology can be viewed at (but not consumed yet) http://dashb-cms-job.cern.ch/dashboard/request.py/cmssitemap
Work Done • The CMS topology has been modified, where group_type is mapped to site-groups and group_namecorresponds to sites defined by VO. • The demo can be viewed at http://dashb-sum-cms/dashboard/request.py/latestresultssmry-sum • Work started on Historical View (New sam-pi were added).
TO DO • Sites and Service availability and reliability is to be implemented in Historical View. • Configuration for the other experiments (ATLAS, ALICE and LHCb). • Modifying the topology as soon as consensus emerges about naming conventions to be followed to support any group type and group name defined in a VO feed.
