1 Stato della Grid di produzione
Alessandro Paolini (INFN-CNAF) Workshop CCR ed INFNGRID 2009 Porto Palau 11 – 15 Maggio 2009

2 Primary components of the production grid
The primary components of the Italian Production Grid are: Computing and storage resources Access point to the grid Services Other elements are as much fundamental for the working, managing and monitoring of the grid: Middleware Monitoring tool Accounting tool Management and control infrastructure Users

3 GRID Management Grid management is performed by the Italian Regional Operation Center (ROC). The main activities are: Production of Infngrid release and test Deployment of the release to the sites, support to local administrators and sites certification Periodical check of the resources and services status Support at an Italian level Support at an European level Introduction of new Italian sites in the grid Introduction of new regional VOs in the grid

4 The Italian Regional Operation Center (ROC)
Operations Coordination Centre (OCC) Management, oversight of all operational and support activities Regional Operations Centres (ROC) providing the core of the support infrastructure, each supporting a number of resource centres within its region Grid Operator on Duty Grid User Support (GGUS) At FZK, coordination and management of user support, single point of contact for users One of 10 existing ROC in EGEE

5 Central Management Team
Central Management Team (CMT) shifts since 4 year ago about 20 supporters, daily shift from Monday to Friday, 2 people per shift, a report is compiled at the end of the shift Grid supervision, ticket followup until resolution Site certification Chasing site managers and experts for quick problem resolution Duplication of tickets (COD tickets and CMT tickets)

6 ROC Shifts: New Model Supporters distinguished into two groups:
IT ROC 1st line 2 people on shift No relationship with C-COD, this is a responsibility of 2nd line Opens tickets Relies on 2nd line support for complex tickets IT ROC 2nd line smaller team of experts (about 3 FTE, including INFN Grid release team) Works on tickets opened by 1st line 1 person on shift IT ROC C-COD representative and interface to C-COD Responsible of suspension in the region Evidenziare il cambiamento nel sistema dei turni

7 Users and sites support
EGEE make use of the GGUS (Global Grid UserSupport) ticketing system Each ROC utilizes different tools interfaced to GGUS in a bidirectional Way. By means of Web services, it is possible to: Transfer tickets from the global to regional system Transfer tickets from the regional to the global system The user groups support, whom ticket will be addressed, are defined Either in GGUS either in the regional systems In the Italian Regional Operation Centre the ticketing system utilized is based on XOOPS/xHelp

8 Sistema di supporto italiano

9 GRID Services Allow you to use the grid resources:
Resource Broker (RB) / Workload Management System (WMS): they are responsible for the acceptance of submitted jobs and for sending those jobs to the appropriate resources Information System (IS): provides information about the grid resources and their status Virtual Organization Management System (VOMS): database for the authentication and authorization of the users Gridice: monitoring of resources, services and jobs Home Location Register (HLR): database for the accounting informations of the usage of resources LCG file catalog (LFC): file catalog File Transfer Service (FTS): file movements in an efficient and reliable way MonBox: collector for local data of R-GMA

11 Servizi Controllati da NAGIOS
Le macchine del cnaf sono controllate da nagios: in caso di fallimenti, sono abilitati l’invio di o di sms In caso di down di un HOST, viene inviato un sms per i seguenti servizi grid: FTS, LFC, WMSMON, VOMS (master E replica), CE, NTP I processi che girano sulle macchine sono controllati ogni 5 minuti. In caso risultino CRITICAL (viene inviato un sms), vengono fatti altri 4 controlli, distanziati di 1 minuto uno dall'altro. Al secondo di questi controlli, quando lo stato del check e' CRITICAL SOFT 2, viene fatto il tentativo di restart del servizio HOST CHECK RESTART FTS FTS AGENTS TO DO FTS BDII LFC lfc-dli SI' lfc-deamon globus-mds mysql VOMS voms ports BDII bdii NO CE site-bdii NTP ntpd WMS WMS-POOL Update dinamico del DNS: I servizi sono controllati ogni minuto. In caso risultino CRITICAL, vengono fatti altri 3 controlli, distanziati di 1 minuto uno dall'altro. Nel caso in cui lo stato CRITICAL persista, viene rimosso l'IP del host che ospita il servizio critico dall'alias top-bdii.grid.cnaf.infn.it Host coinvolti: top-bdii01.cnaf.infn.it top-bdii02.cnaf.infn.it top-bdii03.cnaf.infn.it prod-bdii-01.pd.infn.it Le motivazioni

12 Accounting using DGAS DGAS (Distributed Grid Accounting System) is fully deployed in INFNGrid (13 site HLRs + 1 HLR of 2nd level (testing). The site HLR is a service designed to manage a set of ‘accounts’ for the Computing Elements of a given computing site. For each job executed on a Computing Element (or a on local queue), the Usage Record for that job is stored on the database of the site HLR. Each site HLR can: Receive Usage Records from the registered Computing Elements. Answer to site manager queries such as: Datailed job list queries (with many search keys: per user, VO, FQAN ,CEId…) Aggregate usage reports, such as per hour, day, month…, with flexible search criteria. Optionally forward Usage Records to APEL database. Optionally forward Usage Records to a VO specific HLR. Site HLR Site layer Usage Metering Resource’s layer -Aggregate site info -VO (with role/group) usage on the site. Detailed Resource Usage info Job level info GOC
