AAPI Ops extends this capability with\n*anomaly alerts*, which are triggered whenever Apigee detects unusual API traffic\ndata. The advantage of anomaly alerts is that you don't have to define the exact conditions\nfor each anomaly yourself. AAPI Ops determines the right anomaly conditions using statistical methods,\nand constantly updates them based on recent traffic data.\nUsing anomaly detection, you let Apigee detect traffic and performance issues, rather than\npredetermining the alert conditions yourself.\n| **Important:** \"Anomaly Detection\" describes the Advanced API Operations Anomaly Detection functionality, which is available in the Classic Apigee UI. This functionality is comparable to the \"Operations Anomalies\" functionality in [Apigee UI in Cloud console](https://console.cloud.google.com/apigee). Both are available at this time. See [Operations Anomalies overview](/apigee/docs/api-platform/analytics/operations-anomalies-overview) for information on the Operations Anomalies functionality.\n\nWhen AAPI-Ops detects an anomaly, it displays the event in the Anomaly Events\ndashboard. However, it doesn't automatically raise an alert for\nthe anomaly. If you examine an anomaly in the dashboard and decide you want to be alerted about\nsimilar event in future, you can create an anomaly alert\nand set up a notification, which sends you a message whenever the anomaly is detected.\n\nBefore creating an anomaly alert, make sure you have been assigned the\n[required roles](/apigee/docs/aapi-ops#required-roles-for-aapi-ops)\nfor AAPI Ops.\n\nTo create an anomaly alert in the Alerting policy dashboard, do the following:\n\n1. Open the\n [Create alerting policy](https://console.cloud.google.com/monitoring/alerting/policies/create?) dashboard in the Google Cloud console.\n\n **Note:** Open the Create alerting policy dashboard in a new tab if you want to follow\n the steps below.\n2. Click **ADD CONDITION** . This opens a new window where you can add the alert condition.\n\n\n3. Optional: Add a title for the condition in the **Untitled Condition** field. We'll leave it blank for this example, in which case the condition is given a default title.\n4. In the **Find resource type and metric** field, type\n\n ```\n anomaly\n ```\n\n and then select **Apigee anomaly event count**.\n5. Click **SHOW ADVANCED SETTINGS** and in the **Advanced Aggregation** pane,\n select **delta** in the **Aligner** field. This specifies how the data is\n aggregated over each time period, which you can set in the **Period** field.\n With the **delta** setting, the aggregated value equals the\n final data value in the time period minus the initial data value.\n\n6. In the **Configuration** pane, set the **Threshold** to **0.5**.\n (Any number between 0 and 1 will work for the threshold.)\n With this value, a single anomaly exceeds the threshold and triggers the alert.\n\n7. Click **Add** . This takes you back to the **Create alerting policy** page\n where you can see the condition you just created.\n\nAt this point you can choose to either:\n\n- Click **ADD Condition** to create another condition for the alert, or\n- Click **NEXT** to go to the next step, where you will have the option to [create a notification for the\n alert](#creating-a-notification-for-an-alert), as described in the next section.\n\nIf you don't want to create a notification, click **NEXT** twice\nwithout entering anything to bypass Steps 2 and 3.\n\nClick **SAVE** to save the alert.\n\nCreating a notification for an alert\n------------------------------------\n\nIf you want to be notified immediately when an incident occurs, you can create\na notification for the alert. When the alert is triggered, Apigee sends you\na notification. You can choose any of the following channels to receive\nthe notification:\n\n- Email\n- PagerDuty\n- Slack\n- Webhooks\n\n| **Note:** Currently, to receive a notification, you must add **org** to the **Group by** field in the alert. This requirement will be removed in a future release.\n\nTo create a notification for an alert:\n\n1. If you just created the alert (as shown in the\n preceding example) and are currently viewing the\n **Create alerting policy** dashboard, skip to the next step.\n\n Otherwise, open the\n [**Policies** pane](https://console.cloud.google.com/monitoring/alerting/policies) in the Cloud console Alerting dashboard, and in\n the row for the alert you created, click the three dots icon at the end\n of the row and select **Edit**.\n\n This opens the **Edit alerting policy** dashboard:\n2. In the **What do you want to track?** section, click **NEXT**.\n\n3. In the **Who should be notified** section, select\n **Notification Channels**, where you can choose from existing channels for receiving\n notifications.\n\n If you want to create a new\n notification channel, select **MANAGE NOTIFICATION CHANNELS** . This\n opens the Notification channels dashboard in the Cloud console, where you can\n add channels. See\n [Create and manage notification channels](https://cloud.google.com/monitoring/support/notification-options) for more details.\n4. Click **NEXT**. This displays the options shown below.\n\n5. In the **Alert name** field, enter a name for the alert.\n6. In the **Documentation** field, enter the URL for a web page that provides information on how to fix the issue that caused the alert. The URL will be included in the notification.\n7. Click **Save** to create the alert.\n\nWhen an alert is triggered, you will receive a notification\nproviding a summary of the incident and when it occurred. The notification\nalso contains two links to help you investigate the incident:\n\n- **VIEW INCIDENT**: View the incident in the Cloud console.\n- **VIEW IN APIGEE** : View a timeline graph of API traffic and related data tables in the [API Monitoring Investigate dashboard](/apigee/docs/api-monitoring/investigate)."]]
