Job Monitoring v. Display all the jobs submitted by a VO o. Follow the status of the jobs v. Collect information from different sources o. RGMA, IC Real Time Monitor, BDII, Mon. ALISA, … v. Very useful for VO managers, site admin, users v. Possibility to get the output in different formats Internet Services CERN IT Department CH-1211 Genève 23 Switzerland www. cern. ch/it v. Deployed for ALICE, ATLAS, CMS, LHCb and Vle. Med T 1/T 2 ALICE tutorial -- Pablo. Saiz@cern. ch 6
