 ## Create alerts
 
-Alerts are created by alert rules in Azure Monitor and can automatically run saved queries or custom log searches at regular intervals. You can create alerts based on specific performance metrics or when certain events occur. You can also create alerts on absence of an event, or a number of events are occur within a particular time window. For example, alerts can be used to notify you when average number of sign in exceeds a certain threshold. For more information, see [Create alerts](../azure-monitor/alerts/alerts-log.md).

 Use the following instructions to create a new Azure Alert, which will send an [email notification](../azure-monitor/alerts/action-groups.md#configure-notifications) whenever there's a 25% drop in the **Total Requests** compared to previous period. Alert will run every 5 minutes and look for the drop in the last hour compared to the hour before it. The alerts are created using Kusto query language.
