Alert Trigger Condition
Alert rules that you set are composed of thresholds and comparison rules in the form of "or" or "and"
Alert Trigger Rule
In the alert trigger conditions that you set, one or more rules triggered the alert. In the same group of "and" combination, all rules must be triggered before "and" is counted as "and". If there is a combination of "or" in, a single rule under this "or" or "or" combination meets any one, and an alert is triggered.
Threshold Rule
You can select a metric (error number, error rate, number of affected users, proportion of affected users), and select "greater than" a certain value or a certain percentage 
Comparison rules
You can select a metric (Error Count, Error Rate, Number of Affected Users, or Percentage of Affected Users) and select More than one day or seven days ago to increase the percentage. The calculation method is as follows: (Value in Last 1 Hour-Value in History 1 Hour) /Value in History 1 Hour. If the value is greater than or equal to the selected value, an alert is sent. 
Push rules
Alert frequency: The last one-hour alert task is calculated every time. If the alert task is triggered, the notification mechanism is run.
Example: At 13:00, the system determines whether the rule that you set is triggered is triggered. The notification may be delayed by minutes. You may receive an alert notification at 13:05.

Note: To facilitate alert schedule settings, web-based monitoring alerts are not controlled by webhook settings at the organization level.

We will send the webhook based on the webhook you entered in the new alert plan. Only the sending mailbox is consolidated in the organization.
