---+CCRC'08 Service Map %TOC% ---++Overview The [[http://gridmap.cern.ch/ccrc08/][CCRC'08 ServiceMap]] is a tool for displaying different aspects of the service readiness of the WLCG Computing Infrastructure. the list of services are those provided by the WLCG experiments. There are currently three different view components: * Service Readiness - An evaluation of the service against a list of common deployment questions * Service Availability - Availability of a service * Experiment supplied data - this is data provided by the experiment frameworks to show their view of different aspects of the service e.g. reliability, throughput, usage, etc... ---++Components ---+++ Service Readiness The *Service Readiness map* is designed to show how ready a service by looking at the maturity of the software, the service in general in terms of documentation, process and procedures and the specific deployment at a site. Each question is scored between =0= and =1= (or =-= if not relevant), and the overall readiness is the average of the individual questions. The questions are in three sections, each dealing with a different aspect: * Software Readiness * Service Readiness * Site Readiness ---++++ Software Readiness | * Question * | * Comments * | |High-level description of service available? |with architecture diagam| |Middleware dependencies and versions defined? |OS deps, M/W deps, platforms supported| |Code released and packaged correctly? |Repository + Tagging process, rpms/tarballs| |Certification process exists? | | |Automatic Configuration code exists? |e.g. Yaim, NCM, …| |Admin Guides available? |Installation, monitoring, problem determination| ---++++ Service Readiness | * Question * | * Comments * | |Disk, CPU, Database, Network requirements defined? | | |Monitoring criteria described? | | |Problem determination procedure documented | | |Support chain defined (2nd/3rd level)? | | |Backup/restore procedure defined? | | ---++++ Site Readiness | * Question * | * Comments * | |Suitable hardware used | | |Monitoring implemented | | |Test environment exists | | |Problem determination procedure implemented| | |Automatic configuration implemented| | |Backup procedures implemented and tested| | ---+++ Service Availability The *Service Availability map* shows availability for the VO Critical services. This currently uses either SAM or SLS for the actual results gathered. There is a single configuration file which controls what is displayed in the gridmap. It is a tab separated file, which is shown below: <verbatim> VO Service Rank Comment Tier Data Quality Data Source Data Query Data Tier LHCb CERN VO boxes 10 0 no results for VO SAM VOBOX T0 LHCb CERN LFC service 10 0 no results for VO SAM LFC T0 LHCb VOMS proxy service 10 no results for VO SAM VOMS T0 LHCb T0 SE 7 0 SLS CASTORLHCB T0 LHCb T1 VOboxes 7 1 no results for VO SAM VOBOX T1 LHCb SE access from WN 7 0,1 T0,T1 LHCb FTS channel 7 both CERN to/from T1 & inter T1 0,1 SAM FTS T0,T1 </verbatim> The important field here are : | Field | Usage | | =VO=| Which VO map to show this entry in| | =Service=| The text shown in the box | | =Rank= | The size of the box| | =Data Source= | Where does the data come from - =SAM= or =SLS=| | =Data Query=| The query to use to the source -e.g. SAM node type, or SLS metric name| | =Data Tier=| 0, 1,2 - defines it it shows when you select a specific site| The file is stored in the WLCG Grid Monitoring SVN Repository: =https://www.sysadmin.hep.ac.uk/svn/grid-monitoring/trunk/ccrc08/config/datafiles=. To update the map, you should modify the file =servicelist.txt=. This is automatically syncronized with =gridmap.cern.ch= every five minutes. ---+++ Experiment View
