Description
The rate of performance improvements of the LHC at CERN has had strong
influence on the characteristics of the monitoring tools developed for the
experiments. We present some of the latest additions to the suite of Web
Based Monitoring services for the CMS experiment, and explore the aspects
that address the roughly 20-fold increase in peak instantaneous luminosity
over the course of 2011. One of these user-friendly tools allows collaborators
to easily view, and make correlations among, accelerator configuration
information such as bunch patterns, measured quantities such as intensities,
vacuum pressures, and background conditions, as well as derived quantities
such as luminosity and the number of simultaneous interactions per beam
crossing. An additional tool summarizes the daily, weekly, and yearly
luminosity and efficiency. Finally, we discuss a trigger cross section
and rate fitting service, that uses data from previous runs to validate
current running conditions as well as to serve as a predictive extrapolation
tool for developing triggers for higher luminosity running.
