Instead of the filtering graph on the summary portlet, the expanded portlet gives you the option to
select a user-defined filter from the list, create custom filtering by selecting Advanced Filters, or do
a quick search.
The following are available additional columns, besides the default columns visible in the
Alarms
Portlet
(summary view):
Assigned User —The user currently assigned to this alarm (right-click to do this). The assigned
user can then look for alarms by consulting the Assigned User (AU) column in the display
(concealed by default), or by filtering alarms using Advanced Filters. One can even create an
alarm portlet that filters for a single user’s assigned alarms.
Acknowledged — Indicates whether or not the alarm has been acknowledged. This is controlled by
the Acknowledge and Unacknowledge actions that are available from the popup menu.
Count —A count of the instances of the events that correlate to this alarm. Multiples of what is
essentially the same alarm appear as a single row, but increment this count.
Entity Type —The type of monitored entity.
State —The state (open/closed) of the alarm.
Date Cleared —The date and time that the alarm was closed.
Update Time —The time stamp for when this alarm was updated (for an additional count, the
time the last duplicate was received).
Notification OID —The identifier of the notification displayed as an alarm. This is also the
unique identifier of the Event Definition upon which the alarm was based, which means that
the alarm inherits attributes such as Severity, Resource Propagation, etc. from the Event
Definition that has the same Notification OID.
Equipment —The name for the top-level entity (Managed Resource) emitting the alarm.
Date Assigned —The date and time that the alarm was assigned.
Ack Time —The time the alarm was acknowledged.

by).
Entity Description —The description of the alarmed entity.
Mediation Partition — The mediation partition that received the event (traps, syslog, etc.) that is
correlated to the alarm.
Resource Propagation — Indicates how this alarm propagates through the resource hierarchy, so
as to possibly impact the Alarm State of the top-level device and/or the subcomponents that
are hierarchically associated with the entity that was alarmed. This value is inherited from the
Event Definition upon which the alarm is based.
Equipment —The equipment emitting the alarm.
Ack By —The user that acknowledged the alarm.
Correlation State —The role this alarm plays in any parent/child correlation (for example: To p
level alarm, caused by parent, Blocked by parent
).

Parent/Child Alarm Correlation: Alarm Details Panel on page 290).
