In its summary form, this portlet displays alarms. General > Entity Change SettingsContainer View portlet, or if it is in expanded mode, refresh does not occur automatically, but you can refresh it manually.
A small clock icon appears in the upper right corner of this portlet if auto-refresh is enabled. A small speaker icon appears if audible alerts are enabled. See Audible Alerts for more about those.
The chart can act as a filter, too. For example, clicking the Critical alarms slice means only Critical alarms appear listed. Notice also that the chart “explodes” to highlight the selected slice. Hover the cursor over a portion of the chart and a tooltip with information about that slice also appears. Click exploded slices to return the graph to its unexploded state, and it stops filtering the list by the selected slice.
If the legend appears below the Alarms graph, resize your browser (click and drag the right edge out, then in), and the legend should re-appear to the right of the graph.
Different tooltips appear when you hover the cursor over columns for Entity Name and Device IP.
By default, the chart appears only when there are alarms. See Configuring the Alarms Chart below for options available in configuring the display. See Menu for details about menu items available when you right-click in the summary and expanded portlets. The following columns appear in this screen by default:
Severity -- The alarm severity indicated by the color of the leftmost icon. The severity only has meaning for Alarms and Security Alarms. Informational Alarms get a severity level of Indeterminate. Closed alarms appear without color.
Date Opened -- The date the alarm appeared.
Entity Name -- The entity emitting this alarm (often within the Equipment).
DeviceIP -- The IP address of the equipment where the alarm appeared.
Event Name -- The event associated with the alarm.
Open the Settings >Columns screen to see additional possibilities for columns.
If you hover the cursor over a row in the portlet display, a tooltip appears with information about the alarm. This can include the alarm’s Date Opened, the Entity Name, any alarm Message, Event Name, Alarm and Entity Type, its status as Service Affecting, Notification OID, Equipment, Severity, whether the alarm was Suppressed, or Acknowledged and the Device IP.
If an alarm is Service Affecting, (reflect an impact on a service) it can propagate to appear as components of service- and customer-related alarms. Service-Affecting alarms are of indeterminate or greater severity. The Service Affecting alarm column in this portlet does not appear by default. To see an alarm’s propagation, show that column in the Event Definitions portlet, where it is concealed by default.
Many other columns are available, including those related to suppression, region, any parent alarm, and so on.
See Alarms in Visualizations / Topologies for a description of how alarms appear in the topology portlet. The next section (Expanded Alarm Portlet) describes alarm actions and additional alarm capabilities.
Configuring the Alarms Chart
Turn the chart on or off in the Settings screen’s Chart Options panel. If no data exists for the chart and the Chart option is on, the portlet returns to “no-chart” mode.
When you enable the chart Filtering is disabled since the chart, in effect, provides the filter. When the chart is disabled then filtering options are available.
Settings are saved if you have Admin rights or the Portlet is on your Public / Private pages (like standard behavior).
Changes appear after you click Apply. The Filter panel disappears when you check the Show Chart checkbox.
