1. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t Open projects in Grid Monitoring IT-GS-MDS Section Meeting 25 th January 2008

2. CERN IT Department CH-1211 Genève 23 Switzerland www.cern.ch/i t Internet Services WLCG Monitoring Working Groups 3 groups proposed by Ian Bird to the LCG Management Board, Oct 06. –Goal to improve the reliability of the WLCG grid 2 Grid Services Grid sensors Transport Repositories Views ……. Grid Services Grid sensors Transport Repositories Views ……. System Management Fabric management Best Practices Security ……. System Analysis Application monitoring ……

3. CERN IT Department CH-1211 Genève 23 Switzerland www.cern.ch/i t Internet Services Reliability is our reason Our goal is to improve the reliability of the Grid WLCG availability level for a Tier-2 is 95% –Greater for Tier-0 & Tier-1s What do we need to do ? –Detect problems before users do ! –Reduce time to respond to problems Approach is to put the monitoring and alarms close to the site administrators
