Description
The CMS silicon strip tracker comprises a sensitive area of >200 m2 and 10M readout
channels. Its data acquisition system is based around a custom analogue front-end
ASIC, an analogue optical link system and an off-detector VME board that performs
digitization, zero-suppression and data formatting. The data acquisition system uses
the CMS online software framework, known as XDAQ, to configure, control and monitor
the hardware components and steer the data acquisition. Recent developments have seen
the integration of the CMS offline software framework, known as CMSSW, within the
online data acquisition system. This provides many new features and services within
the online environment, such as distributed analysis within CMSSW, access to geometry
and conditions data, and a monitoring framework. We review how the monitoring
frameworks available within both XDAQ and CMSSW will be used to assess the
operational state of the hardware components of the strip tracker readout system
during data-taking and provide real-time feedback to shifters in the CMS control
room. We will report on the software components, the chosen architecture, the various
monitoring streams available, and our experiences of commissioning and operating
large-scale systems at the tracker integration facility.
