For example, if a sub-alarm goes from green to orange or red, but the selected contribution
is yellow, the incident template will interpret it as yellow.
The Invert contribution allows performing a logical NOT calculation on sub-alarms. This
feature can be used, for example, to report alarms from GPI inputs. It can also be used to
handle cases where an error is expected, and not seeing an error is a sign that something
probably went wrong. The table below describes the result of inverting sub-alarms:
Selecting the Faults only contribution causes a sub-alarm to be mapped to NORMAL unless
it’s in one of the fault statuses—usually CRITICAL, MAJOR, and MINOR. The list of fault
statuses can be modified by using the setFaultSeverities( ) property. See the GSM Scripting
Manual for details.
Sub-alarm Status Inverted Contribution
NORMAL ERROR
MINOR NORMAL
MAJOR NORMAL
CRITICAL NORMAL
NON-EXISTENT NON-EXISTENT
PENDING PENDING
DISABLED DISABLED
UNKNOWN UNKNOWN
Note: If the sub-alarm’s fault condition is cleared, its contribution will always be
green, unless the value specified in the Contribution column is black.
