Alarm, Resolved, Insufficient data, Triggered, and Expired are supported.
- Alarm: The metric value reached the alarm threshold, and an alarm has been triggered but not cleared for the resource.
- Resolved: The metric value went back to the normal range, and the resource alarm was cleared.
- Insufficient data: No monitoring data has been reported for three consecutive hours, and this is generally because the instance has been deleted or is abnormal.
- Triggered: An event configured in the alarm policy triggered an alarm.
- Expired: The monitored resources or alarm policies in the alarm rule were adjusted, so the original alarm record status expired.
