    Alarm Detail Monitor (Service View)

    Use the Alarm Detail monitor to sort alarms, view an alarm in depth, and to assign a disposition to an alarm.

    By clicking the Details icon, you can access the Alarm Detail monitor from any of the four alarm monitors available on the main page in Fault mode (Severity, Category, Current, or State). It is also available from the Current Active Monitors available from the Summary tab in Monitor mode.

    This topic describes:

    Finding Specific Alarms

    Use the Alarm Detail monitor to locate a specific alarm, research the events causing the alarm, and to assign a disposition to the alarm. When an alarm is highlighted in the sorting sequence, the events contributing to the alarm are listed in Event Details and the variable settings are shown in Event Attribute Detail.

    To locate an alarm and to assign a disposition to the alarm:

    1. Sort the list using the Display list. Sorting choices vary depending on how you arrived here. View Sorting Alarms for details on sorting options.
    2. Review the sorted list. Each entry shows a minimum of one to a maximum of nine fields. These fields are described in Table 1.
    3. Examine the events and event attributes that contributed to sending the alarm. Events and event attributes are discussed in Reading Events and Investigating Event Attributes.

    Table 1: Alarm Detail Fields

    Field

    Value

    Shown in Detailed View by Default

    Name

    The alarm name.

    Yes

    ID

    A system and sequentially-generated identification number.

    No

    Assigned To

    If assigned to an individual, it shows the name of the person assigned; otherwise, it shows System to mark that the alarm is still unassigned.

    Yes

    Severity

    The severity of the alarm. Severity levels are:

    • Critical—A critical condition exists; immediate action is necessary.

    • Major—A major error has occurred; escalate or notify as necessary.

    • Minor—A minor error has occurred; notify or monitor the condition.

    • Info—An informational message; no action is necessary.

    Yes

    Service Name

    The name of the service for which the alarm was generated.

    Yes

    Customer

    The name of the customer associated with the service for which the alarm was generated.

    Yes

    Service Type

    The type or protocol of the service for which the alarm was generated.

    Yes

    Entity ID

    The identification of the entity responsible for causing this alarm. The Entity ID is the key for correlation of events into an alarm. The Entity ID could be a MAC address of a radio or an IP address of the device.

    Yes

    Source

    The IP address of the device or network element that generated the alarm. The SNMP agent is located at the source IP. In most cases, the source IP is the IP address of the switch or controller.

    No

    Acknowledged

    Indicates if the alarm has been acknowledged.

    Yes

    Source

    The IP address of the device or network element that generated the alarm. The SNMP agent is located at the source IP. In most cases, the source IP is the IP address of the switch or controller.

    No

    Creation Date

    The date and time the alarm was first reported.

    No

    Last Updated

    The date and time that the information for the alarm was last modified.

    Yes

    Updated By

    Either the system or the last user who modified the alarm.

    No

    Sorting Alarms

    Sort the alarms based on the following parameters from the drop-down lists:

    • Severity

    • State

    • Service

    • Time (You can choose only time spans ending now, for example, Last 12 hours.)

    Click Search to filter the alarms and display the alarms based on the search criteria.

    You can also use Searching Alarms in the Tasks pane to perform searches using multiple arguments. With multiple arguments, you can isolate a single alarm from a long alarm list.

    Reading Events

    When you select an alarm in Alarm Detail, the Event Detail table updates with information about the events that are associated with the alarm. Table 2 lists the fields in Event Detail.

    Table 2: Event Detail Fields

    Field

    Value

    Name

    The event name; also known as the SNMP trap name.

    ID

    A system-generated, hexadecimal code that uniquely identifies the event.

    Description

    If the event is an SNMP event, it is shown as a system-generated event.

    Type

    The type of event, either fault or system alert.

    Category

    The category of the event message. The category corresponds to the alarm categories shown in the Alarms by Category monitor and the Alarm Settings window.

    Source

    The identification of the entity that is the cause of this event ; it is not necessarily the ID of the event that generated the event.

    Originator

    The identification of the entity that generated this event, for example, the switch IP or controller IP address.

    Time Updated

    The date and time of the last update to the event.

    Investigating Event Attributes

    The Event Attribute Detail window reflects the variables set during the event. In SNMP terminology, these attributes are known as variable bindings or varbinds. These attributes can provide key information about triggers. For example, if a fan fails, the attribute field could indicate the location of the fan in the chassis.

    Changing the Alarm State

    When an alarm is first reported, it is considered an active alarm. To change the alarm state, to assign the alarm to a person, or simply to record notes about the alarm, use the buttons on Alarm Details. These buttons are:

    • Acknowledge—Use this button to acknowledge or record that the alarm is known and is being addressed.

    • Clear—Use this button to clear or remove the alarm. The clear state says that the issue sending the alarm has been resolved and no long requires attention.

    • Annotate—Use this button to record actions taken to resolve the alarm.

    • Assign—Use this button to assign active or acknowledged alarms to staff.
