Chapter 14 Alarm Monitoring and Management
14.3.6 Controlling the Conditions Display
14.3.6.1 Retrieving and Displaying Conditions
The current set of all existing conditions maintained by the alarm manager can be seen when you click
the Retrieve button. The set of conditions retrieved is relative to the view. For example, if you click the
button while displaying the node view, node-specific conditions are displayed. If you click the button
while displaying the network view, all conditions for the network (including ONS 15454 SDH nodes and
other connected nodes) are displayed, and the card view shows only card-specific conditions.
You can also set a node to display conditions using the time zone where the node is located, rather than
the time zone of the PC where they are being viewed. See the “14.3.1 Viewing Alarms With Each Node’s
Time Zone” section on page 14-4 for more information.
14.3.6.2 Conditions Column Descriptions
Table 14-6 lists the Conditions window column headings and the information recorded in each column.
Table 14-5 Conditions Display
Button Action
Retrieve Retrieves the current set of all existing fault conditions, as maintained by
the alarm manager, from the ONS 15454 SDH.
Filter Allows you to change the Conditions window display to only show the
conditions that meet a certain severity level or occur in a specified time. For
example, you can set the filter so that only Critical conditions display on the
window.
Note There is a Filter button on the lower-right of the window that allows
you to enable or disable the filter feature.
Exclude Same Root
Cause
Retrieves conditions that obey a root-cause hierarchy (for example, LOS
supersedes and replaces LOF).
Table 14-6 Conditions Column Description
Column Information Recorded
New Indicates a new condition.
Date Date and time of the condition.
Node Shows the name of the node where the condition or alarm occurred. (Visible in network
view.)
Object The object for an HPmon or LPmon.
Eqpt Type Card type in this slot.
Shelf For DWDM configurations, the shelf where the alarmed object is located. Visible in
network view.
Slot Slot where the condition occurred (appears only in network and node view).
Port Port where the alarm is raised. For HPTerm and LPTerm, the port refers to the upstream
card it is partnered with.
Path Width Indicates how many VC-4s are contained in an alarmed path. (For any non-VC-4 object,
such as a VC-3, the column is blank.) This information complements the alarm object
notation, which is explained in Table 14-3.
