Calibration & Monitoring M.N Minard General monitoring tasks

Calibration & Monitoring M.N Minard Monitoring software architecture (07/02/08) Histogram adders L0Tell1 (CC-PC) EFF (HLT), Calibration Farm Histogram producers Histogram saversHistogram presenter Histogram consumers and producers Histogram Database (for display options) Histogram consumers ECS (PVSS) ROOT Insert Data into DB Monitoring Farm

Calibration & Monitoring M.N Minard Questions from the monitoring tools developpers Needs in terms of Configuration & controls Configuration –Control pc + few nodes = calibration farm –ODIN should send calibration events to the farm In normal run In stand alone calorimeter What rate ‘( depends of algoritms time)

Calibration & Monitoring M.N Minard Questions from the monitoring tools developpers Controls –PVSS project as subfarm project –Buffer manager – event builder –Histogramm producer Already in sofware developped by Olivier (24K) Histogramm volume to be defined Length of accumulation to be useful to define What to save and for how long –1TB available for ALL detectors Limitation of disk space

Calibration & Monitoring M.N Minard What to do to enter this monitoring scheme Definition of Calorimeters needs Define the control to be done on each histogramm set –Experience from the current data taking Define the frequency of the checks Understand what can be archived Define the alarms to be transmitted ( few word vector) Trigger database update.. Tools should be available in mid-march
