Health And Performance Monitoring Of The Online Computer Cluster Of CMS
/ Bauer, Gerry (MIT) ; Behrens, Ulf (DESY) ; Bouffet, Olivier (CERN) ; Bowen, Matthew (CERN) ; Branson, James (UC, San Diego) ; Bukowiec, Sebastian Czeslaw (CERN) ; Ciganek, Marek (CERN) ; Cittolin, Sergio (UC, San Diego) ; Coarasa Perez, Jose Antonio (CERN) ; Deldicque, Christian (CERN) et al.
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. [...]
