LHCOPN minutes OPERATIONS Some simplification of the operational procedures have been implemented, notably it's no longer needed to create ticket for not service-impacting events. Guillame wil leave IN2P3. Bruno Hoeft (De-KIT) is now the new responsible for the LHCOPN Operations WG. MONITORING Following Jason's presentation on perfSONAR and the US-ATLAS use-case, and John's presentation of Sander's work on the LHCOPN dashboard, there was a discussion on perfSONAR-ps vs perfSONAR-MDM. The totally distributed nature of the perfSONAR-ps solution was deemed attractive, as was the ease of installation (ISO-CD) and the work that US-ATLAS has done on visualisation (including alarm generation using Nagios). With strong backing from ATLAS, it was decided that perfSONAR-ps would be installed in the LHCOPN Tier0 and Tier1 sites. All the Tier1s present (7?) supported the idea. John, Jason and the Monitoring Working group will drive this.
