# 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.

1. In the **Set evaluation behavior** section, click **New evaluation group** to open the dialog.
2. Give the group a name, such as **Alerts group**, set the **Evaluation interval** to **1m**, then click **Create**.
3. In the **Pending period** field, enter **1m**. This is how long the condition must stay true before the alert fires.
4. 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.
