Grid. ICE The eyes of the grid A monitoring tool for a Grid Operation Center Collaboration: INFN, EDT, LCG Sergio Andreozzi, Sergio Fantinel, Gennaro Tortone last update: 07/10/2020 17: 48 Mirco Mazzucato Infn -Padova 37

Grid. ICE base architecture and features • The tool is meant to address the problem of grid monitoring from the GOC viewpoint (VOs managers, sites supervisors) • Collection of different level metrics: low level (CPU load, memory/disk usage per host), service level (gatekeeper, gsiftp, …), high level (VO resource usage) • It is based on well known and widely deployed grid services: EDG-WP 4 fmon service for the collection of the measures at the site low level; MDS-GIS structure and interface with the integration of an extended GLUE schema to collect the information from the grid sites. • Automatic discovery of all the available resources, from a single network adapter of a computational site node to high level services (computational/storage). • The ability to collect Experiment specific measures (e. g. , CMS CMKIN/CMSIM event production) • Historical tracking of all the metrics with the ability of plotting and programmed alarm generation (e. g. , e-mail, sms) last update: 07/10/2020 17: 48 Mirco Mazzucato Infn -Padova 38

Grid. ICE status and release • GUI reporting the status of the available resources in different ways aggregated per VO or per SITE with detailed description of all different components (see next slide) to give a number of different viewpoint of the testbed status/behaviour. • Generation of graph for aggregated metrics (e. g. , jobs, disk space) • Simple client side installation with a single RPM! • Software and instructions to install the monitoring server. • Deployment status: currently, a set of important testbeds are being monitored by Grid. ICE: • CMS-LCG 0 production • LCG 1 Certification • LCG 1 deployment • Grid. it • Data. TAG last update: 07/10/2020 17: 48 Mirco Mazzucato Infn -Padova 39

Grid. ICE Plans • Short term (foreseen for november ’ 03) • Monitoring of collective grid services: • ability to add/configure any type of service (e. g. , Resource Broker, Logging and Bookkeeping, Batch Server, Resource Locator Service, …); • for every service the set of most important demons/processes will be tracked and monitored • Long term (one year and half from now) • Develop a new monitoring service structure following the GMA proposal based on event driven paradigm using new technology to achieve a more scalable mechanism; the following technologies are under evaluation: JMS/OGSA/WEB SERVICES; XML to improve message exchange portability and compatibility. last update: 07/10/2020 17: 48 Mirco Mazzucato Infn -Padova 40
