The following is a list of web applications that will be used in the October ISOC Operations Simulation, with a short description, their status and to-do list.

The purpose of this document is to collect comments to help us prioritize the work to get the ready for the October deadline.

Data Quality Monitoring

Scope

This application will provide output histograms and data trends resulting from the Fast Monitoring, Digi and Recon processing. The driving process is the L1Proc; root files from each of these processing steps will be registered with the data catalog and picked up by the application in order to display quality histograms. Separate processes will load Digi and Recon tuple files to ingest them into a database for the data trending.

Status

It is currently possible to display histograms from Fast Monitoring, Digi and Recon.

We have a first implementation of the code to ingest trending data into general purpose database tables and managed to produce plots from the web application. The result of this effort was that we need to create new database tables specific to this application.

To-Do List

• Alarm Handling
  • The Fast Monitoring process should output an xml file with a list of the alarms/warnings/errors detected on the produced monitoring histograms
  • This file should be registered with the data catalog (is it there already?)
  • A notification should be added to the Logging application which should point to the Data Quality Monitoring application (is it possible to add the desired target link as part of the notification's metadata?)
  • The file needs to be ingested producing summary and detailed information on the alarms/warnings/errors
