This section describes the following portlets and editors related to alarms, events, and automation:

Alarms Portlet
• Alarm Editor
• Setting Audible Alerts
Alarms Portlet
The Alarms portlet on the Home page displays the pie chart and the color legend.
By default, access the portlet by selecting Home, Alarms/Events, or Alarms/Events > Hierarchical
View, and
Topology > Hierarchical View from the navigation bar.
In its summary form, this portlet displays alarms. See
General > Entity Change Settings on page
34 for the way to set the summary portlet refresh interval. The default is 40 seconds. If this portlet
is on the same page as the Hierarchical 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
Using Extended Event Definitions on
page 341 for more about this feature.
The chart acts as a filter, too. For example, clicking the
Critical alarms slice means only Critical
alarms are listed. 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 and the list to its original state.
Different tooltips appear when you hover over the Entity Name and Device IP columns. Such
tooltips are available if the question mark appears when you hover over the field.
