Overview Enabling Grids for E-scienc. E • Current monitoring landscape • Grid Service Monitoring WG • Operations Automation Team EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 2
Current Monitoring Landscape Enabling Grids for E-scienc. E • SAM + Gridview – referent availability info + alarms • Gstat – version 2 based on Nagios under development – focused on BDII checking • Nagios – CE regional instance – grid site-level prototype • Dashboard – CMS, Atlas • Custom VO monitoring – Mon. ALISA – Alice VO EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 3
Current Monitoring Landscape Enabling Grids for E-scienc. E • BDII – depends on Yaim – GLUE Schema 2. 0 close to Public comment • R-GMA – primarily for accounting system APEL • Grid. ICE – not deployed in g. Lite 3. 1 • Vast of custom solutions EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 4
Grid Service Monitoring WG Enabling Grids for E-scienc. E • Established in 2006. • Review and integrate existing solutions, improve reliability • Results – – Grid probes and data exchange specification Grid site monitoring prototype (Nagios) MSG – a Message System for Grid (Apache Active MQ) Gridmap visualisation tool • Finished with EGEE-II https: //twiki. cern. ch/twiki/bin/view/LCG/Grid. Service. Monitoring. Info EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 5
Operations Automation Team Enabling Grids for E-scienc. E “This team will be tasked with coordinating monitoring tools and developments, and will have a specific goal of advising on strategic directions to take in terms of automating the operation – replacing manual processes with automated ones in order that the overall level of operations effort can be significantly reduced in any long term infrastructure. ” EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 6
Operations Automation Team Enabling Grids for E-scienc. E • Group reports to – SA 1 leader – ROC managers • Milestones – high-level architecture roadmap (mid-May) – detailed implementation plan (end-June) – deployment plan (end-June) • CE region members – Marcin Radecki (COD) – Emir Imamagic (Nagios) • Mandate – https: //edms. cern. ch/document/901705 EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 7
Operations Automation Team Enabling Grids for E-scienc. E • Nagios evolution – multisite configuration generation – sensors development • SAM evolution – – Nagios as execution framework MSG as transport mechanism NCG component for providing configuration distribution over ROCs § CE & CERN ROCs first • Dynamic DNS load-balancing – managed by distributed monitoring system EGEE-II INFSO-RI-031688 CE Meeting / Grid Monitoring Tools 8
