13.4.1 Viewing Alarms With Each Node’s Time Zone
By default, alarms and conditions are displayed with the time stamp of the CTC workstation where you
are viewing them. But you can set the node to report al arms (and conditions) using the time zone where
the node is located by clicking Edit > Preferences, and clicking the Display Events Using Each Node’s
Timezone check box.
13.4.2 Controlling Alarm Display
You can control the display of the alarms shown on the Alarms window. Table 13-4 shows the actions
you can perform in the Alarms window.
13.4.3 Filtering Alarms
The alarm display can be filtered to prevent display of alarms with certain severities or alarms that
occurred between certain dates. You can set the filtering parameters by clicking the Filter button at the
bottom-left of the Alarms window. You can turn the filter on or off by clicking the Filter tool at the
bottom-right of the window. CTC retains your filter activation setting. For example, if you turn the filter
on and then log out, CTC keeps the filter active the next time you r user ID is activated.
Table13-4 Alarm Display
Button/Check Box/Tool Action
Filter button Allows you to change the display on the Alarms window to show only
alarms that meet a certain severity level, occur in a specified time frame,
and/or reflect specific conditions. For example, you can set the filter so that
only Critical alarms display on the window.
If you enable the Filter feature by clicking the Filter button in one CTC
view, such as node view, it is enabled in the other views as well (card view
and network view).
Synchronize button Updates the alarm display. Although CTC displays alarms in real time, the
Synchronize button allows you to verify the alarm display. This is
particularly useful during provisioning or troubleshooting.
Delete Cleared Alarms
button
Deletes alarms that have been cleared.
AutoDelete Cleared
Alarms check box
If checked, CTC automatically deletes cleared alarms.
Filter tool Enables or disables alarm filtering in the card, node, or network view. When
enabled or disabled, this state applies to other views for that node and for
all other nodes in the network. For example, if the Filter tool is enabled in
the node (default login) view Alarms window, the network view Alarms
window and card view Alarms window also have the tool enabled. All other
nodes in the network also have the tool enabled.
