Abstract
In this paper we describe the architecture and operation of the Real Time Monitor (RTM) This is arguably the most popular dissemination tool within the EGEE Grid. Having been used, on many occasions including GridFest and LHC inauguration events held at CERN in October 2008. The RTM gathers information from EGEE sites. The system consists of three main components. The RTM server queries the LB servers at fixed time intervals, collecting job related information and storing this in a local database. Job related data includes only job state (i.e. Scheduled, Waiting, Running or Done) along with timing information but also other attributes such as Virtual Organization and Computing Element (CE) queue. This information can be visualized through either a 2D or 3D Java based client with live job data either being overlaid on to a 2 dimensional map of the world or rendered in 3 dimensions over a globe map using OpenGL.
