Alarm service

  • Parameters
    • Metrics: The monitoring metrics taken from ApsaraDB for HybridDB.
    • Statistical cycle: The recurring period of time in which the alarm system checks whether monitoring data has exceeded the alarm threshold.
    • Statistical method: The calculation method and resulting value used to determine whether the data has exceeded the threshold specified in an alarm rule, which can be average, maximum, minimum, or sum.
    • Consecutive times: An alarm is triggered after a metric value continuously exceeds the threshold specified in an alarm rule for some set of consecutive cycles. For example, if the consecutive times is set to three, then the conditions specified for an alarm rule must be met for three consecutive statistical cycles before an alarm is triggered.
