Severity
The Severity parameter sets the alarm severity.
Severity Function
Critical The Critical severity level indicates that a service affecting condition has occurred and an
immediate corrective action is required. Such a severity can be reported, for example,
when a managed object becomes totally out of service and its capability must be restored.
Major The Major severity level indicates that a service affecting condition has developed and an
urgent corrective action is required. Such a severity can be reported, for example, when
there is a severe degradation in the capability of the managed object and its full capability
must be restored.
Minor The Minor severity level indicates the existence of a non-service affecting fault condition
and that corrective action should be taken in order to prevent a more serious (for
example, service affecting) fault.
Such a severity can be reported, for example, when the detected alarm condition is not
currently degrading the capacity of the managed object.
Warning The Warning severity level indicates the detection of a potential or impending service
affecting fault, before any significant effects have been felt. Action should be taken to
further diagnose (if necessary) and correct the problem in order to prevent it from
becoming a more serious service affecting fault.
