The CMS experiment's online cluster consists of 2300 computers and 170 switches or routers
operating on a 24-hour basis. This huge infrastructure must be monitored in a way that the administrators
are pro-actively warned of any failures or degradation in the system, in order to avoid or minimize
downtime of the system which can lead to loss of data taking. [...]

The CMS Electronic Logbook
Reference: Poster-2010-149
Note: RT2010: 17th IEEE NPSS Real Time Conference, Lisboa, Portugal
Keywords: The CMS ELogbook ELog Model–View–Controller MVC Model View Controller Oracle Portal CMS ELogbook CMS ELog
Created: 2010. -1 p
Creator(s): Bukowiec, S; Bauer, G; Beccati, B; Behrens, U; Biery, K [...]
The CMS ELogbook (ELog) is a collaborative tool, which provides a platform to share and store information about various events or problems occurring in the Compact Muon Solenoid (CMS) experiment at CERN during operation. The ELog is based on a Model–View–Controller (MVC) software architectural pattern and uses an Oracle database to store messages and attachments. The ELog is developed as a pluggable web component in Oracle Portal in order to provide better management, monitoring and security.
