Description
ATLAS is one of the four experiments under construction along the Large Hadron
Collider (LHC) ring at CERN. The LHC will produce interactions at a center of mass
energy equal to $\sqrt s~=~14~TeV$ at a $40~MHz$ rate. The detector consists of more
than 140 million electronic channels. The challenging experimental environment and
the extreme detector complexity impose the necessity of a common scalable distributed
monitoring framework, which can be tuned for the optimal use by different ATLAS
sub-detectors at the various levels of the ATLAS dataflow. This note presents the
architecture of this monitoring software framework, and describes its current
implementation, which has already been used at the ATLAS beam test activity in 2004.
Preliminary performance results, obtained on a computer cluster consisting of 700
nodes, will also be presented, showing that the performance of the current
implementation is in the range of the final ATLAS requirements.
