Trigger Monitoring o Monitoring Architecture o o Event Monitoring o o 10 th November, 2005 Types of monitoring Data sources Monitoring tasks Decoding status Development directions Athena-based monitoring Reflection and outlook Trigger Monitoring 1

Types of Monitoring o DCS o o o Operational Monitoring o o o VME based data Status, error counts, rate histograms Simple Event Monitoring o o o Not really considered part of ‘MWG’ monitoring But should be correlated with other data Internal to TDAQ Single detector data Athena Based Monitoring o o 10 th November, 2005 Allows inter-detector correlations Requires event building Trigger Monitoring 2

Monitoring Data Sources Monitoring Stream o ‘Rod Crate’ Level o Data. Flow Level o SFI Athena PT o Sampling can occur in several places Choice of framework at each level is flexible/uncertain ROS Event Dataflow o NB actually also means PPM, CP, JEP crates! Low level, TDAQ framework GNAM Framework o ROD EF SFO 10 th November, 2005 Trigger Monitoring 3

Monitoring Tasks (subset) o Crate monitors o o o Run in SBC of PPr, CP, JEP, ROD and TTC crates Publish histograms/information to OH/IS Event fragment sampling o Run in ROD crate (? ), ROS PCs o o o Event fragment analysis o o Run in SFI, SFO(? ) Full event analysis o o Run in dedicated L 1 Calo PCs in USA 15 (how many? ) Publish results to OH/IS Full event sampling o o L 1 Calo consists of 6 ROSes 3 PPr ROSes, 1 CP ROS, 1 JEP ROS, 1 Ro. I ROS Run in N PCs in Monitoring Farm (N is small number!) Event Filter Monitoring (? ) Status Display of all available monitoring information 10 th November, 2005 Trigger Monitoring 4

Monitoring Development Directions o Start using GNAM o o 4 CPMs and 2 CMMs Start using OHP o o o Real data not available Can read data from file Data generated from ‘slice’ simulation 8 PPMs Replaces histo. Display and oh_display Could already be tested with production and point-1 histograms? Develop status display tools 10 th November, 2005 5 9 U RODs TTC and ROS simulation Trigger Monitoring 7

Athena Based Monitoring o Essential for Calorimeter Comparisons o o o Also paves way for Event Display o o Was cludged at test beam Requires built events (SFI, EF, SFO, ‘offline’) ATLANTIS already has trigger information But need work to get there o Real link between online and offline o o ie genuine bytestream. Converters Athena algorithms to make histograms 10 th November, 2005 Trigger Monitoring 8

Reflection and Outlook o Much work to do o o But direction is relatively clear Little progress on monitoring itself o o Though some progress on necessary tools Why so slow? o o o Higher priority placed on module verification … and calibration developments Lack of real data to monitor Participation in MWG However things are hopefully looking up o o 10 th November, 2005 Additional manpower Increasing use of modules in ‘real’ data taking Trigger Monitoring 9
