• If you wish to exclude alarms in this level from the global alarm calculation, then
clear the Include in global alarm check box.
• To rank this level’s contribution to your system’s global alarms, click the Global
alarm contribution box, and then select the appropriate value from the list.
• Passthrough: This is the default value. Alarms in this level will pass their status
unaltered to the global alarms.
• Critical, Major, Minor, Disabled: It is possible to override the error status of
alarms when they are triggered. This is useful when, for example, a device is
only able to report a status of either normal or error, but you want the error
condition to be considered as minor in the global alarm calculation.
• Invert: Alarms in this level will pass the opposite of their status to the global
alarms. This can be used, for example, to report alarms from GPI inputs, or 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:
Alarm status Inverted contribution
NORMAL ERROR
MINOR NORMAL
MAJOR NORMAL
CRITICAL NORMAL
NON-EXISTENT NON-EXISTENT
PENDING PENDING
