Alarm Filtering

Typically alarm filtering is performed through details stipulated at the PeriView

Alarm Viewer; however, this still requires that all alarms generated be forwarded to

the viewer. In cases where alarm production is excessive, traffic overhead can place

an undue burden on the system, thereby degrading overall performance. In order to

avoid a situation like this, alarm filtering has been instituted at a lower (daemon) level,

allowing for a boost in system performance and/or distinct customizing to meet site

and customer needs.

Filtering can be accomplished through either the alarmd or alarmf daemon, or

both (alarmf can also be run as a utility - see the latter portion of “Notation

Functionality” on page 207). Generally in a single or limited node environment

filtering through alarmd is sufficient. However in situations where there are many

nodes in a network, each running an instance of alarmd, or where alarm traffic has

become substantial, further consolidation of filtered alarms can be performed by

alarmf. Depending on system needs and configuration, there can be present either

one or multiple instances of alarmf. This can reduce the overall number of alarms

ultimately delivered to the viewers, and depending on the actions stipulated by the

user, can reduce the frequency with which system operators or administrators are

required to interact with the system. Any number of filtering criteria can be applied in

situations where multiple instances of the daemons exist, and filtered and unfiltered

daemons can be combined as well. Additional details on these scenarios are provided

in the sections that follow, and at “Filtering Examples” on page 213.

Manual. For additional information concerning the alarm daemons, see VOS
