摘要：
ATLAS is a particle physics experiment on Large Hadron Collider at CERN. The experiment produces petabytes of data every year. The ATLAS Computing model embraces the Grid paradigm and originally included three levels of computing centers to be able to operate such large volume of data. With the formation of small computing centers, usually based at universities, the model was expanded to include them as Tier-3 sites. The experiment supplies all necessary software to operate typical Grid-site, but Tier-3 sites do not support Grid services of the experiment or support them partially. Tier-3 centers comprise a range of architectures and many do not possess Grid middleware, thus, monitoring of storage and analysis software used on Tier-2 sites becomes unavailable for Tier-3 site system administrator, therefore Tier-3 sites activity becomes unavailable for virtual organization of the experiment. In this paper ATLAS off-Grid sites monitoring software suite is presented. The software suite enables monitoring on sites, not covered by ATLAS Distributed Computing software.
