Configuring Aggregation Rules

Prerequisites

You have the following operation permissions: Set Aggregation Rules.

Context

• A rule is valid only to the alarms or events reported after the rule is enabled.
• In an aggregation rule, when the number of times that the same alarm or event (with the same alarm or event ID) is reported by the same NE in a specified period meets the trigger condition, an aggregation is triggered and a new aggregated alarm is generated. The alarms that meet all the conditions of the alarm aggregation rule are the original alarms. When an aggregated alarm is generated based on the rule, the correlative alarms are marked as original alarms. To view all original alarms, you can select Original alarms for Associated alarm ID when setting the filter criteria for current alarms.
• If an aggregated alarm generated based on the alarm aggregation rule is cleared, its correlative original alarms are cleared. If the original alarms are cleared, their correlative aggregated alarms are also cleared. To handle an aggregated alarm, handle the faults corresponding to the original alarms one by one.
• A maximum of 1000 custom aggregation rules can be created.
• By default, the rules are sorted by the enabled and disabled states, and the rules in the same state are sorted by update time in descending order.
• If the interval between the time when an alarm is generated and the time when the alarm arrives at the NMS is longer than 5 minutes, the alarm does not match the aggregation rule even if the alarm meets the conditions.
• On the page for creating an event aggregation rule, only the Generate an aggregated alarm and Generate an aggregated alarm and mask all original events options are provided in the Aggregation Action area. The information about the aggregated alarm generated based on the event aggregation rule is the same as that of an original event. The original events of the aggregated alarm cannot be viewed.

Procedure

1. Choose Device Management > Alarms Management > Alarm Settings from the main menu.
2. In the navigation pane, choose Aggregation Rules.
3. Create an aggregation rule.
   1. On the Aggregation Rules page, click Create, and choose the desired rule type from the drop-down menu.
   2. In the Basic Information area, set the rule name, description, and whether to enable the rule.
   3. In the Conditions area, set the name, sources, and advanced conditions of the target alarm or event. If alarms or events reported by the selected alarm or event source meet the configured advanced conditions, aggregation analysis is performed.
   4. In the Aggregation Parameters and Aggregation Action areas, set aggregation parameters and aggregation action. For details about the parameters, see Table 1.
   5. Click OK.

Related Tasks

• Deleting a rule: You can select a redundant rule from the rule list and click Delete to reduce the rule maintenance workload.
• Enabling/disabling a rule: You can select a rule that is not used temporarily from the rule list and click Disable. To use a disabled rule, select the rule and click Enable.
• Migrating rules: You can click Export on the rule page of the source system to export rules. Then, click Import in the target system to import the rule file exported from the source system to the target system.
• Backing up, collecting statistics on, and reviewing rules, and modifying rules in batches: You can click Export on the rule page to export rules and back up, review, and collect statistics on the rules. If you need to modify rules in batches, you can modify the rules in batches in the exported rule file. Then, click Import on the rule page to import the modified rule file.

Parameter Description

The following uses the parameters for creating an alarm rule as an example, and they are similar to those for creating an event rule.
