Overview

AOM allows you to set alarm rules. With alarm rules, you can set event conditions for services, set search analysis, keyword counting, and SQL query for resource logs, or set threshold conditions for resource metrics. An event alarm is generated when the resource data meets the event condition. If a metric value meets a threshold condition, a threshold alarm will be reported. If there is no metric data, an insufficient data event will be reported. When the log data of a resource meets the preset alarm condition, a log alarm is generated.

Alarm rules are classified into metric alarm rules, event alarm rules, and log alarm rules. Generally, metric/log alarm rules monitor the real-time usage of resources (such as hosts and components) in the environment. When there are too many resource usage alarms and alarm notifications are sent too frequently, you can use event alarm rules to simplify alarm notifications, quickly identify a type of resource usage problems of a service, and resolve the problems in a timely manner.

The total number of alarm rules is 3000. If the number of alarm rules has reached the upper limit, delete unnecessary rules and create new ones.
