1 MAGO Monitoring All Grid Objects Anna Jannace 1, Carmine Spizuoco 1, Francesco Adinolfi 1, Giovanni Bracco 2 1- Consorzio Campano per lInformatica e lAutomazione Industriale (C.R.I.A.I.) [f.adinolfi, a.jannace, 2- ENEA This poster describes the CRESCO subproject 1.2 MAGO: Monitoring All Grid Objects of CRESCO. This High Performance Computing system was installed to provide the required computing power to the CRESCO project applications and to integrate CRESCO HPC system into ENEA-GRID infrastructure. This project is the result of the collaboration between ENEA and C.R.I.A.I. Consorzio Campano di Ricerca per linformatica e lautomazione industriale. The process of Monitoring & Discovery resources is needed in HPC system to find and solve the malfunctions arising in the infrastructure. MAGO aims to realize an innovative tool to monitor ENEA-Grid resources. The main ENEA-GRID software components are: Multi-site resource manager LSF Multicluster, OpenAFS distributed file system, Kerberos 5 authentication, GUI based on CITRIX technologies. After a technological survey, the Information System model was chosen in according to the GLUE Schema standard (http://glueschema.forge.cnaf.infn.it/). The study was based on the ENEA Grid infrastructure. Its characteristics imply the choice of Ganglia (http://ganglia.info/) as the core of the monitoring system. The picture describe the monitoring system and its components: MAGO WEB, CORE and DB. One of the peculiarities of the environments is the capability to be decentralized, allowing availability and robustness, also in case of crash involving specific computers. It was chosen in this work to create a centralized and hierarchical structure, because the system monitors Grid resources, but it does not manage them, and because such approach allows to minimize maintenance on single host.

HIGH LEVEL VIEW Usage of different technologies made it possible to implement a flexible, modular, scalable, fault tolerance monitoring tool. To understand this complexity is important to observe what and how many objects constitute the system, then in which way they interact with each other. WEB Configuration Viewing Alarms Inclusion of new metrics Query on database AFS Container of source code, application, script Saving configurations for each site and host Storing Metrics CORE Decrease of collected metrics by the demons of Gmetad Ganglia MAGO environment automatic installation on Host Information Transfer on the server site Fetch and decoding input metrics MAGO DB Large database containing information about: Configuration Metrics Measurements Subnets Alarms CORE The core of MAGO is a distributed three level based architecture Livello SERVER CENTRALE Mago Core System Livello Server di SITO Livello HOST Direzione Dellinformazione The path shows the information flow from Server Site origin to Master Server destination WEB VIEW The MAGO Web Application has an user interface providing the following features: Configuration of each subsystem Access to the system through a secure connection on a CRESCO front-end host Usage of capabilities provided by AFS and LSF systems already available in ENEA-Grid Capability Robustness Reliability Modularity Scalability Fault tolerance MAGO project extends the functionalities offered by Ganglia package URL APPLICATION http//www.afs.enea.it:8080/Mago/ DOCUMENTATION REFERENCE CRIAI ENEA Summary
