Alert rule state and health

Each alert rule can generate one or more alert instances—one alert instance for each series or dimension, as shown in the multi-dimensional alert example.

Each alert instance of the same alert rule represents a different target and can be in a different state; for example, one alert instance may be Normal while another is Alerting.

Multi dimensional alert rule. The alert rule state and alert rule health are determined by the state of the alert instances.

The alert rule state and alert rule health are determined by the state of the alert instances.
