Expanded Alarm Portlet
The expanded Alarm portlet appears when you click the plus (+) in the top right corner of the smaller screen.
This displays listed alarms, totals by severity for alarm types found, and Snap Panel details of a selected alarm. By default this screen adds the first of the following columns to those visible in the Event History’s summary screen view. To add the others listed here, right click, and select Add Columns to change the screen appearance.
All severity totals appear in expanded view. This display updates automatically when alarms clear.
The following are available additional columns, besides those visible in the Alarms summary portlet:
Count -- A count of the instances of the alarm. Multiples of the same alarm appear as a single row, but increment this count.
Entity Type -- The type of monitored entity.
Message -- Any message that accompanies the alarm / event.
Alarm State -- The state (open / closed) of the alarm.
Date Cleared -- The date and time that the alarm was closed.
UpdateDate 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.
Equipment -- The name for the entity emitting the alarm.
Acknowledged -- True or False.
Assigned User -- The user who has been assigned 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 for his / her alarms in Advanced Filters. One can even create an alarm portlet that filters for a single user’s assigned alarms.
Date Assigned -- The date and time that the alarm was assigned.
Ack Time -- The time the alarm was acknowledged.
Cleared By -- The user who cleared the alarm.
MIB Text -- The alarm’s MIB Text.
Rather than filtering with the pie graph, the expanded portlet lets you either the pick list at the top left, or create custom filtering by clicking Advanced Filters.
Right clicking an alarm lets you select from the following menu items:
Edit -- Access the editors for the Alarm (see Alarm Editor) or Event Definition (see Event Definition Editor).
Details -- Open a Details screen for the alarm itself, not the entity emitting it. (see Equipment Details for an example of this type of screen). This contains information like the MIB text, any Event Processing Rules invoked, and a Reference Tree for the alarm. It also lets you configure alarm correlation. See Alarm Correlation: Alarm Details Panel.
Visualize -- Display a topology map that includes the selected alarm(s). See Display Strategies for more about these maps.
Acknowledge / Unacknowledge Alarm -- Acknowledges the selected Alarm(s). The current date and time appear in the Ack Time field. Unacknowledges previously acknowledged alarm(s), and clears the entries in the Ack By and Ack Time fields. The red “unacknowledged” icon appears in the expanded portlet and turns to a green check “acknowledged” icon the alarm has been acknowledged.
Assign User -- Assign this alarm to one of the users displayed in the sub-menu by selecting that user. An icon also appears in the expanded portlet indicating the alarm has been assigned to someone.
Clear Alarm -- Clearing the alarm removes the alarm from the default alarm view and marks it as a candidate for the database archiving process (DAP). Essentially it is an indication to the system that the alarm has been resolved/addressed. If your system has enabled propagation policies, clearing recalculates dependent alarms.
Direct Access -- Open an SNMP Mib Browser to the device alarmed, a CLI Terminal (Telnet window) to the device alarmed, or ICMP Ping the device alarmed. Only those available appear in the subsequent menu.
Email Alarm -- E-mail the alarm. Enter a subject an e-mail address to which you want to mail the alarm’s content, and click the + to add to the list of addresses (the minus deletes them). Then click Send Email. Clicking Cancel ends this operation without sending e-mail. See SMTP Configuration for instructions about setting up e-mail from Open Manage Network Manager. See Alarm Email for an example of what the content looks like.
Show Performance -- If the equipment is monitored, this displays a performance dashboard for the alarmed equipment. See Dashboard Views for more about these.
Aging Policy -- This lets you select a policy that determines how long this alarm remains in the database. See Redcell > Database Aging Policies (DAP) for information about configuring such policies.
View as PDF -- Create an Acrobat PDF document containing this portlet’s contents.
To resync alarms--that is, query the device for its alarm state--resync the device.
Hover your cursor over the Device
IP Address column, and a tooltip appears with information
about the alarm source’s Model, Vendor,
Discovery Date, and a Ping Rate
bar graph. This can also include other
device-dependent items. For example: bar graphs to display the % CPU [utilization], %
Memory, and Description.
The convention indicating such tooltips are available is the question mark that appears next to the cursor when you hover it over the displayed field.
Alarm Snap Panels
These include the following:
Alarm Details -- The source, Severity, Message, Date Opened, and so on. See also Alarm Correlation: Alarm Details Panel below.
MIB Details--The Notification OID, and MIB Text for the selected alarm.
Reference Tree -- The connection between the alarm and its source in tree form.
Total Occurrences by Date -- A graph of the total occurrences of this alarm, by date.
