Description
The CMS tracker has more than 50 millions channels organized in 16540 modules each
one being a complete detector. Its monitoring requires the creation, analysis and
storage of at least 4 histograms per module to be done every few minutes. The
analysis of these plots will be done by computer programs that will check the data
against some reference plots and send alarms to the operator in case of problems.
Fast visual access to these plots by the operator is then essential to diagnose and
solve the problem. We propose here a graphics interface to these plots similar to the
one used by Google Maps to access satellite images (which uses the AJAX technique).
We start with a "tracker map" i.e. an image that contains in a single screen a planar
visualization of all modules. The operator can zoom on this image accessing first
histogram miniatures drawn on top of the modules and then the full histograms. As in
Google Maps the user can pan the image at any resolution and can switch between
different representations showing different kind of plots.
