Configuring Alarms
Managing Virtual Alarms
(green) or error (red), but you want the error condition to be considered as minor
(yellow) in the virtual alarm calculation. To change a sub-alarm’s contribution, click in
the Contribution column, and then select the status you want the virtual alarm to use
when an error occurs.
For example, if a sub-alarm goes from green to orange or red, but the selected
contribution is yellow, the virtual alarm will “see” yellow (the virtual alarm’s overall
status may still depend on other sub-alarms).
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 is in one of the fault statuses—usually CRITICAL, MAJOR, and MINOR. Refer to
the iControl User Guide for more information.
8Repeat from step 5, until you have added all the required sub-alarms.
9 Specify a name for the new virtual alarm in the Name box.
You may adjust the default path, if necessary, so that alarms be grouped in the desired
way.
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 (NORMAL), unless the value specified in the Contribution
column is black (DISABLED).
