Set evaluation behavior
Evaluation behavior sets how often the query runs, how long a problem must last before the alert fires, and how long the alert keeps firing after the condition resolves.
In this milestone, create an evaluation group, then set the pending period and keep firing for.
In the Set evaluation behavior section, click New evaluation group to open the dialog.
Give the group a name, such as Alerts group, set the Evaluation interval to 1m, then click Create.
In the Pending period field, enter 1m. This is how long the condition must stay true before the alert fires.
In the Keep firing for field, select None. This is how long the alert keeps firing after the condition resolves.
Your evaluation schedule is set. Next, you configure no-data and error handling and choose a contact point.
