# How to Create Alerts and Set Up Monitoring in App Platform

App Platform is a fully managed Platform-as-a-Service (PaaS) that deploys applications from Git repositories or container images. It automatically builds, deploys, and scales components while handling all underlying infrastructure.

In addition to [viewing insights](https://docs.digitalocean.com/products/app-platform/how-to/view-insights/index.html.md), you can monitor and set up alerts for certain events. App Platform provides the following app-level and resource-level alerts:

- **App alerts**: The following events can trigger app-level alerts:

  - Started deployment
  - Failed deployment
  - Cancelled deployment
  - Successful deployment
  - Failed domain configuration
  - Successful domain configuration
  - Failed to scale
  - Successful scaling
  - Failed job invocation
- **Metric alerts for app resources**: The following metrics can trigger resource-level alerts:

  - CPU
  - RAM
  - Restart count
  - Function activation count
  - Function average duration
  - Function average wait time

By default, when you create a new app, App Platform creates email alerts for failed deployments and failed domain configurations.

**Note**: App Platform may occasionally redeploy apps for infrastructure maintenance. If you have alerts configured for deployments, you may receive alerts when apps are redeployed due to maintenance.

## Set Up App Alerts

To manage alert policies, go to the [**Apps** page](https://cloud.digitalocean.com/apps), select your app, then click the **Settings** tab.

In the **Alert Policies** section, click **Edit**. Click an alert to expand it, then enable or disable it. Set the notification method to be email or Slack. When finished, click **Save**.

## Monitor Resource Metrics

You can configure alerts for metrics such as CPU usage, memory usage, or restart counts. Alerts are triggered when a metric is above or below a specified threshold for a defined duration. You can apply alerts to all components or only to specific ones.

To set a metric alert, go to the [**Apps** page](https://cloud.digitalocean.com/apps), select your app, then click the **Settings** tab.

On the **Settings** page, scroll to the **Alert Policies** section and click **Edit**. In the **INSIGHTS** section, click **Create Alert Policy**.

In the **Add Alert Policy** section:

- Select an option in the **Metric** dropdown menu.
- Select **Above** or **Below**.
- Enter a value in the **Threshold %** field.
- Select an option in the **Duration** dropdown menu.
- Enter an email address or click **Connect Slack** to receive alert notifications.
- Select the components you want the alert policy to apply to.
- Click **Save**.
