By setting alarms rules, you can define event conditions for services or threshold conditions for resource metrics. An event alarm is generated when the resource data of a service meets the event condition. A threshold alarm is generated when the metric data of a resource meets the threshold condition. An insufficient data event is generated when no metric data is reported.

Alarm rules are classified into threshold rules and event alarm rules. Generally, threshold rules are used to monitor the usage of resources such as hosts and components in the environment in real time. When there are too many resource usage alarms and notifications are sent too often, use an event alarm rule to identify a type of resource usage problems for simplified notification.

The total number of threshold rules and event alarm rules is 1000. If the number of alarm rules has reached the upper limit, delete unnecessary rules and create new ones.
