Alarms and log files
All alarms that appear in the BCM Element Manager Alarms Panel are logged in the
alarms.systemlog file. This file is capped at 1 MB in size; when the file reaches this size, a new
alarms.systemlog file is started. The BCM keeps the current file as well as three previous files. The
file is also capped and a new file is started when the BCM system is rebooted.
You can retrieve the alarms.systemlog files (the current file plus the three previous files) from the
BCM system using the Log Management task in the BCM Element Manager. You can view the
files using the BCM Log Browser. For more information, see Chapter 12, “Managing BCM50
Logs,” on page 301.
Alarm severities
Alarm severities are as follows:
By default, alarms are displayed in the Alarm Banner. The BCM sends SNMP traps for alarms
with a severity of Major and Critical. The only exception is PVQM alarms; for these alarms, the
BCM sends SNMP traps for all severity levels.
Table 49 provides the default mapping of each severity level against the Alarms Panel, alarms set,
LEDs, and SNMP.
Table 48 Alarm Severities
Alarm Severity Description
Critical Immediate corrective action is required due to conditions such as loss of
service, loss of bandwidth, outage, loss of data, and/or functionality
Major Urgent corrective action is required due to conditions such as pending loss
of service, outage, loss of data, and/or functionality
Minor Corrective action is required to prevent eventual service-affecting
degeneration
Warning Indicates the detection of a potential or impending service-affecting
condition and that some diagnostic action is required
Information Indicates audit-type information, such as configuration changes
