Chapter 1 Alarm Management Overview

1.3 Alarm Severity Alarm Severity Based on severity, alarms have four levels: critical, major, minor, and warning. For a descriptions of the four levels, refer to Table 1-1. Table 1-1 Alarm Severity Description Alarm Severity

Description

Critical

Services are affected seriously. Alarms of this level require immediate removal.

Major

Services may be affected. Alarms of this level must be removed.

Minor

Services will not be affected, but alarms of this level should be handled to avoid more serious faults.

Warning

An error that may affect services is detected. This problem should be analyzed and removed to avoid possible serious faults.

Redefining Alarm Severity When the NetNumen U31 system is initialized, alarm severity is set by default. You can adjust alarm severity based on service requirements and environmental requirements. For how to set alarm severity, refer to "2.9 Redefining an Alarm Severity".

1.4 Alarm States Alarm States Alarm states are as follows: l l l l

Unacknowledged and uncleared Acknowledged and uncleared Unacknowledged and cleared Acknowledged and cleared

Alarms in unacknowledged and uncleared and acknowledged and uncleared states are called Active Alarms. Alarms in unacknowledged and cleared and acknowledged and cleared states are called History Alarms.

Alarm State Change Model For the alarm state change model, see Figure 1-3.

1-3 SJ-20150616154424-006|2015-06-30 (R1.0)



Figure 1-3 Alarm State Change Model

l

Acknowledge/unacknowledge an alarm If an alarm is acknowledged, it is handled by maintenance personnel, and its state changes to acknowledged. You can also unacknowledge an alarm.

l

Clear an alarm If a fault is removed, alarm states change from uncleared to cleared. This type of alarms are called history alarms, and they are saved to the database of the NetNumen U31 server. You can clear an alarm manually, but if the fault that results in the alarm is not removed, this alarm will be raised again.

1.5 Alarms and Notifications Alarms During the operation of managed NEs or the EMS system, if a fault occurs, an alarm is raised. Users can be informed of the fault, and thus handle the fault. After the fault is removed, the alarm is cleared.

Notifications Notifications are messages about the operation of managed NEs or the EMS system. With notifications, you can be informed of the operation states of all modules.

Difference Between Alarms and Notifications l l

Alarms are resulted from faults or exceptions. If they are not removed, services may be affected. You can acknowledge and clear an alarm. Notifications are only messages about the operation of managed NEs or the EMS system. They do not affect services. You cannot acknowledge and clear a notification.

2.5 Creating Rules for Automatically Processing Alarms This procedure describes how to set rules for automatically processing alarms.

Context If an alarm or notification complies with certain conditions, the NetNumen U31 system is triggered to process the alarm or notification based on alarm rules. Table 2-6 Alarm Rule Descriptions Rule

Description

Alarm filtering rule

Filters alarms that match specified conditions. By default, the filtered alarms are discarded to the database or not displayed on the GUI. If an alarm meets both the alarm restraining rule and the alarm filtering rule, it is filtered by the alarm restraining rule.

Alarm acknowledging

Acknowledges alarms that match specified conditions.

rule Alarm clearing rule

Clears alarms that match specified conditions.

Alarm delaying rule

Handles intermittent alarms. When alarms meeting the specified conditions are generated, they will not be reported immediately. Instead, they will be reported after a certain delay. If these alarms are restored within the delay, you can choose whether to send them into the history alarm database.

Alarm merging rule

Merges alarms that are caused by the same failure and display one alarm to represent those alarms. You can create multiple rules, but the conditions of the new rule cannot overlap those of the rules already in existence.

Alarm persisting rule

Triggers a user-defined action, if an alarm meeting the specified conditions remains in the specified state and the duration reaches the threshold. You can create multiple rules, but the conditions of the new rule cannot overlap those of the rules already in existence.

Alarm counting rule

If the number of times that an alarm complying with particular conditions is raised exceeds the threshold, a new alarm is raised. 2-11

SJ-20150616154424-006|2015-06-30 (R1.0)



Rule

Description

Alarm forwarding rule

Forwards specific alarms through Email messages or SMS messages to users who are responsible for handling them.

Alarm masking rule

Sends the masking conditions to NE agents, and then the NE agents do not report the specified alarms to the EMS. This rule can only be set for NE agents and devices managed by NE agents. If the NE agents are disconnected or stop operating, only suspended masking rules can be created.

Alarm triggering script

If an alarm meeting the specified conditions occurs, the preset MML script

rules

is triggered.

NAF alarm filtering rule

Filters alarms that match specified conditions. The filtered alarms will not be reported to the NMS.

Alarm restraining rule

With this rule, users can use specified root alarms to restrain specified

by NE

NE-correlated alarms. Alarms that restrain other alarms are called root alarms, and the restrained alarms are called correlated alarms. Correlated alarms will be displayed when there is no root alarm. When root alarms exist, correlated alarms will not be displayed.

Alarm restraining rule

With this rule, users can use specified root alarms to restrain specified

by NE type

NE type-correlated alarms. Alarms that restrain other alarms are called root alarms, and the restrained alarms are called correlated alarms. For a root alarm and its correlated alarms, their NE types must be the same. In addition, the occurrence position of the specified root alarm must be the same as that of the specified correlated alarm, or be the parent node of the correlated alarm's occurrence position.

Notification filtering rule

Filters notifications that match specified conditions. Filtered notifications will neither be displayed on the GUI nor be stored in the database. This rule only applies to new notifications that are generated after the creation of this rule.

Repeated notification

Filters notifications (with the same location and notification code) that

filtering rule

repeat within the specified time from the last notification (including filtered ones). The filtered notifications will neither be displayed on the GUI nor be stored in the database. They will be discarded directly. You can see the occurrence times of a notification by querying notifications. This rule only takes effect for notifications that are reported after the creation of this rule. You can create multiple rules, but the new rule cannot overlap the conditions of the rules already in existence.

Rule

Description

Frequent alarm rules

Merges the repeatedly reported and recovered alarms with the same alarm ID within a dynamic interval or a fixed period. Alarms are merged based on dynamic intervals or fixed periods. The correlated alarms generated during the effective period can be merged without being stored in the historical alarm database. If the number of frequently reported alarms is greater than the threshold, the counting cell of the root alarm is marked in red.

2.7 TOP Alarm Suppression Rules A TOP alarm suppression rule indicates that if the number of times that the alarms with the same alarm ID are reported during a specified time period is more than the preset times, the alarms are suppressed. When the number of times that the alarms are reported is less than the preset times, the suppression process is stopped. When an alarm is suppressed, a root alarm is generated. During alarm suppression, the repeatedly reported alarm with the same alarm ID is called a correlated alarm and is incorporated into the root alarm. The number of correlated alarms is counted until the suppression termination conditions are met. During alarm suppression, only the root alarm instead of the correlated alarm is reported northward. The root alarm is cleared when the rule expires or is removed manually. The TOP alarm suppression rule is effective only for the alarms that are reported after the settings are activated.

2.7.1 TOP Alarm Suppression Setting Tab On the NetNumen U31 client, select Fault > Setting > TOP Alarm Suppression Setting. The TOP Alarm Suppression Setting tab is displayed, see Figure 2-8. Figure 2-8 TOP Alarm Suppression Setting Tab
