• 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
