Nowadays several management protocols coexist, offering heterogeneous information about events which occur in managed objects. Some information is superfluous and in some cases unnecessary. Operators can be satured with irrelevant fault information. Alarm correlation and filtering processes are necessary to simplify the events analysis and identification of their main cause. Fault management increases is significance in complex environments like power utilities. This paper analyzes the standardization necessary to maintain an alarm distributed management environment, applied to a specific field, alarms in SCADA (Supervisory Control and Data Acquisiton) environments. We have designed an alarm MIB. This MIB refers to both operating system and SCADA alarms. Through this MIB we can manage the most important faults arisen in the operating system. We also propose an architecture for a management system, consisting of both agent and manager. The agent can use either the SNMP, CMIP, or proprietary protocols. Manager supports alarm composition, polling, alarm correlation, protocol and information mapping, historics management and filtering in a metamanagement distributed environment. The management of each SCADA environment is made by a MIS (management information system) and there is a continuous flow of information among all the MIS at the power utility, distributing alarm management. An experimental prototype, which implements the proposed architecture, is presented. |
