BCM fault management scope

You can view and manage real-time alarms generated by the BCM system. Alarms arise from components that run on the system; these alarms indicate faults or informational conditions that may require resolution from the system administrator. Examples of alarm conditions include:

• a T1 circuit on the system is down

• an administrator stopped a service that runs on the BCM

You can receive alarm information through any of the following means:

• the Alarms Panel in the Business Element Manager

• the Alarm Banner in the Business Element Manager

• Simple Network Management Protocol (SNMP) traps for remote

management of faults

12 Fault and performance management fundamentals

• email notification - alarm email notification can be per alarm or based on

alarm severity

You can manage alarms and alarm information by:

• configuring alarm settings, for example, filter alarms so that only the

desired subset of alarms display in the Business Element Manager Alarms Panel are sent as SNMP traps

• administering alarms, for example, acknowledge selected alarms and

clear the alarm log

• email notification, for example configuring settings so you receive

notification about all critical alarms

BCM alarms

Software components that run on the BCM system generate alarms related to BCM services and applications.

Each component includes a range of alarm IDs, so each BCM alarm retains a unique alarm ID.

Alarms and log files

The system logs all alarms that appear in the Business Element Manager Alarms Panel in the alarms.systemlog file. This file is capped at 1 MB in size; when the file reaches this size, the system creates a new alarms.systemlog file. The BCM keeps the current file as well as three previous files. A new file starts when the BCM system reboots.

You can retrieve the alarms.systemlog files (the current file and the three previous files) from the BCM system using the Log Management task in the Business Element Manager. You can view the files using the BCM Log Browser. For more information, see the BCM 5.0 Administration and Security Guide (NN40170-603).

Alarm severities

By default, all major and critical alarms are visible on the alarm set, sent as email or SNMP traps. Most, but not all alarms are visible in the Business Element Manager Alarm Panel. When BCM raises a Critical, Major, Minor and Warning alarm, this is reflected in the Alarm Banner.

Alarm administration

Alarm information can be delivered to you by any of the following means:

• on a table on the alarms panel

• email notification

Nortel Business Communications Manager 5.0

Fault and Performance Management

NN40170-701 01.01 Standard

• on the alarm banner on the bottom right corner of the Business Element

Manager

• on the alarm set

Alarms and the Alarms Panel

You can view real-time alarm information using the Alarms Panel in the Business Element Manager. Each alarm has a unique identifier. Alarms are displayed in the Alarms table, sorted by date and time by default, with the newest at the top of the table. The Alarms table displays from 100 to 1000 alarms. For information about setting the number of alarms that are displayed, see Configuring the alarm set (page 24). The Alarms table contains the following elements:

• Time — the date and time of the alarm

• Alarm Acked — indicates whether the Business Element Manager has

acknowledged the alarm.

• Alarm ID — the unique alarm ID associated with the alarm

• Severity — the severity of the alarm (Critical, Major, Minor, Warning, and

Information)

Fault and performance management fundamentals 13

• Problem Description — a description of the alarm condition

• Component ID — the process that has generated the alarm, in a 3-part DN

format. The component ID always identifies the system as a BCM, includes the name of the system that generated the alarm, and identifies the component that generated the alarm. In this way, remote monitoring stations can easily identify what type of system generated an SNMP trap and which system generated the trap.

When you select an alarm in the table, an Alarm Details pane is displayed for the selected alarm. The Alarm Details pane displays the following information:

• Time — the date and time of the alarm

• Problem description — a description of the alarm condition

• Problem resolution — the course of action for the alarm

You can acknowledge an alarm to indicate that you are troubleshooting an alarm. You can specify whether to include acknowledged alarms in the Alarm Banner so that the alarm count remains concise.For more information about the Alarm Banner, see Alarm banner (page 14).The alarm list in the Business Element Manager remains after BCM reboots.

Alarm banner

You can use the Alarm Banner in the Business Element Manager to view current alarm counts and recent alarm activity on the BCM system. The Alarm Banner appears on the bottom-right corner of the Business Element Manager window. The Alarm Banner is visible at all times, so you do not have to navigate to the Alarms Panel to view alarms. If you notice a change in alarm conditions in the Alarm Banner — for example a red spike in the Critical category — you can navigate to the Alarms Panel to view the actual alarm.

Alarm banner

The Alarm Banner provides counts of Critical, Major, Minor, and Warning alarms; Information alarms are not included. You can specify whether to include acknowledged alarms in the Alarm Banner.

Each alarm severity counter has a graph, which represents a data sample of the last 20 polling intervals. The system polls for new alarms every 30 seconds by default. The graph has a color to indicate a data change. The colors are as follows:

Table 1 Alarm graph colors

Color Indicates

Green There are no alarms of this severity, or there are

alarms of this severity but the count has decreased since the last polling interval.

Yellow There are alarms of this severity, but they are older

than at least one polling interval.

Red A new alarm has occurred since the last polling

interval.

If you clear the alarm log from the Business Element Manager, the alarms displayed on the Alarm Banner are also cleared and reset to 0.

Alarm set

You can view critical and major alarms on a telephone set on the BCM system. This allows a system administrator to monitor alarm activity without having a Business Element Manager and a personal computer.

You can specify the telephone to serve as the alarm set in the Business Element Manager. The telephone set used for alarms must have a 2-line display and three soft keys.

The alarm set displays an alarm as follows:

XXXXX-YYYY

Where XXXXX is the alarm ID and YYYY is additional alarm information.

The following options are available when an alarm is sent to the alarm set:

• Time — indicates the date and time when the alarm occurred

• Clear — use this soft key to remove the alarm from the alarm set

Fault and performance management fundamentals 15

Attention: Clearing an alarm from the alarm set does not change the status of alarms on the Business Element Manager or reset the LEDs on the front panel of the unit.

Attention: When an alarm is displayed on the alarm set, it remains visible until you clear the alarm by using a softkey on the alarm set. More recent alarms are not be displayed until the current alarm is cleared on the alarm set.

The following figure shows an example of an alarm on the alarm set.

Alarm to email forwarding

You can forward alarms to email and use the email forwarding option to

• monitor alarms on the BCM

• forward alarms to a third party for the BCM support

Destinations you have provisioned to receive alarms have the following parameters:

• variable number of TO recipients

• variable number of CC recipients

•From field

• Simple Mail Transfer Protocol (SMTP) server field that can be IP address

or hostname

• SMTP port

• option to enable Transport Layer Security (TLS)

• option to enable authentication

• user name and password for SMTP authentication

The following alarm details are included in the alarm email notification:

•title

— hostname

— alarm severity

— alarm ID

• email body

— date of alarm

— alarm ID

— alarm severity

— alarm description

— alarm resolution

Use the Test Alarm feature in the Business Element Manager to test the settings.

If any of the destinations do not successfully receive the email, the alarms are not retransmitted. To view the alarms, log into the Business Element Manager or download the alarm.systemlog.

Emails are not sent under the following conditions:

• network failure between the BCM and the SMTP server

• invalid SMTP server address or SMTP port

• conditions causing the SMTP server to reject the email including wrong

TO address, wrong FROM address, or incorrect user ID and password details

Alarm profile

An alarm profile simplifies alarm management by automatically enabling or disabling alarms in bulk based on their severity. This can be done for each supported alarm destination. BCM supports five profiles, as detailed in Table

The BCM supports the following alarm destinations:

• Business Element Manager alarm list — viewable in the alarm panel of the

Business Element Manager

• Email — alarm is sent as an email to any provisioned destinations

Fault and performance management fundamentals 17

• SNMP — alarm is sent as a SNMP trap to any configured trap receivers

• Alarm set — alarm is sent to the BCM designated telephone set

See Table 2 for details on the alarm profile types.

To refine alarms that should be sent to a specified destination, select the alarm profile name and the alarm destination, and then apply settings. For more information about selecting an alarm profile, seeNotify and select an

alarm profile (page 26).

Alarms and LEDs

When an alarm condition occurs on the system, the Status LED on the front of the BCM main unit, changes to reflect the alarm condition. In normal operation, both LEDs are green. All alarms with a severity of Major and Critical change the Status LED to solid red, except in the event of a Failed Startup Profile, which is indicated by a flashing red LED.

Using the Business Element Manager, you can reset the Status LEDs on the front pane of the BCM 5.0 to a normal state.

Attention: Once the Status LED has changed to red in response to a Critical or Major alarm condition, it remains in the alarmed state until you reset it using the Business Element Manager.

For information about LEDs and what they indicate, see System LEDs

reference (page 65).

SNMP traps manager for remote monitoring

You can use an SNMP trap manager to remotely monitor BCM alarms via SNMP traps. A trap is an indication from the BCM system to configured trap managers that an alarm has occurred in the BCM system. Any BCM alarm can generate an SNMP trap.

If you want the BCM to send SNMP traps, you must first configure the SNMP agent using the Business Element Manager. You must enable an SNMP agent and then configure how the system handles SNMP trap notifications. For information about configuring SNMP settings, see Enabling or disabling

SNMP traps for alarms (page 26).

The BCM system uses the Small Site Events Management Information Base (MIB) for alarms. The trap format is specified in this MIB. You capture and view traps using any standard SNMP fault monitoring framework or trap watcher.

By default, the BCM sends SNMP traps for alarms with a severity of Major and Critical. You can change the default alarms that are set for SNMP to limit the volume and type of SNMP information, and to control essential information that is transferred on the network. For information about how to change the default alarms, see Configuring the alarm set (page 24).

Alarm configuration scope

Although the BCM system provides a default mapping of alarms that are displayed in the Alarms table and that are sent as an SNMP trap, you may want to monitor additional alarms using either of these means, or you may want to reduce the number of alarms that are displayed in the Alarms table or sent via SNMP traps.You can specify how each alarm is handled, according to your business requirements.

You can specify the following settings for alarms:

• the maximum number of alarms displayed in the Alarms Panel (from 100

to 1000)

• whether to enable or disable SNMP traps for selected alarms; by default,

the system sends all Critical and Major alarms as SNMP traps if you specify one or more trap destinations

• whether to display selected alarms in the Alarms table; by default all

Critical, Major, Minor, and Warning alarms are displayed in the Alarms table

• whether to display selected alarms on the alarm set; by default, only

Critical and Major alarms are sent to this set

Fault and performance management fundamentals 19

You can also test a selected alarm. This allows you to test whether the LED or SNMP traps are functioning as expected. Testing an alarm generates an alarm in the system. Alarms generated using the Test Alarm feature are identified in the Alarms table by the words “Test Event” in the alarm Problem Description field.

For more information about using SNMP to monitor your system see, the BCM

5.0 Configuration—Telephony Guide (NN40170-502).
