2. ACTIVITY REPORT

2.1. Progress Summary

Regular maintenance of national Nagios/SAM, regional dashboard, TopBDII. Regular maintenance of WMS, LB, VOMS, UI, MyProxy services provided for Auger and VOCE.

New hardware at prague_cesnet_lcg2 installed (ugluk5 - host for virtual machines, new disk array with 66PB of RAW disk space installed, not in production yet). New backup VOMS server configured - voms2.grid.cesnet.cz - works as a proxy issuing backup service for Auger, VOCE and Meta VOs. DPM database and CreamCE database moved to a hardware with better IO performance at praguelcg2. New CreamCE instance at prague_cesnet_lcg2 for testing compatibility with NGI_CZ version of torque.

Regular activities of EGI CSIRT members performed, including weekly and monthly EVO meetings. We continued to coordinate the security monitoring activity of the team, focusing mainly on the Security dashboard. The dashboard has been intergrated with the production operations portal and the CSIRT has started an internal campaign to overview and evaluate in detail the results available from there. Several improvements and bug fixes have also been applied to the EGI Pakiti server.

Top level BDII round robin put in production (configured, monitored by EGI tools, documented).
