Alarm system: developments Distributed alarm system • Several servers to actively control different services • A central collector server – Alarm management – e-mail / SMS notification • SMS tested, but not yet deployed – reporting/logging • Implementation: 1 month fulltime

Monitoring system • At present ~ 300 systems monitored – package developed at CNAF • Needed to have a tool to collect a plethora of data from systems • Implemented to be efficient in collecting data – ~ 100 variables collected from each WN – ~ 140 variables from servers – Daily, weekly, monthly & yearly plots • Need standard interface to exchange data with other monitoring tools (e. g. Gridice) to avoid multiple collection of same data
