Description
The Physics and Data Quality Monitoring framework (DQM) aims at providing a
homogeneous monitoring environment across various applications related to data taking
at the CMS experiment. Initially developed as a monitoring application for the 1000
dual-CPU box (High-Level) Trigger Farm, it quickly expanded its scope to accommodate
different groups across the experiment. The DQM organizes the information received by
a number of monitoring producers and redirects it to monitoring consuming clients
according to their subscription requests, in the classic publish-subscribe paradigm.
Special care has been given to the modularity and stability of the system with the
clear separation of the production of the monitoring information from the
distribution and processing. We will describe the features of the DQM system and
report on first measurements of its performance on a small subfarm prototype.
