2. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 2Author etc Outline Purpose and goals Organizational matters Current activities Facilities Operations requirements

3. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 3Author etc Monitoring Task Force Purpose –To have a coherent collection of monitoring systems, well integrated and effective at describing the status of the CMS software and computing systems Goals –Establish a single entity in CMS responsible for monitoring development coordination –Establish a better liaison with Dashboard and IT –Establish a work plan Expected duration 6-9 months

4. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 4Author etc Organisational matters Weekly meetings Full day workshop on May 11 –Goal is to establish a work plan

5. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 5Author etc Current activities Describe the current “state of the art” Collect official requirements from all the stakeholders –Facilities Operations –Data Operations –Analysis operations –Database project –DQM (data quality monitor) project

6. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 6Author etc Facilities Operations requirements Reorganize and relocate the CAF monitoring Use data popularity to decide what datasets reside on disk (EOS) Set up a HappyFaces instance at CERN –Open question about what web server to use –Evaluate as possible framework for shifts Implement a proper disk/tape space monitoring for sites Coordinate development and deployment of SLS sensors Have the Google calendar and the Dashboard use the same collector for downtimes Reorganize the computing shift pages using a framework (to choose) Implement alarms across the board –The SSB should generate alarms as it was already requested dy ATLAS –More extensive usage of SLS alarms

7. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 7Author etc Future topics DataOps and AnaOps are in the process of defining their requirements CRAB 3 monitoring
