 2. On the **Delivery Overview** tab, select a time period from the time picker. <br/> ___Optional___: *Turn the metric toggle off if you'd like to see the quantity of events as counts instead of percentages. Delivery Overview shows percentages by default.*
 3. Select a success or discard step to view additional context about the events that passed through that step.

 With Source Debugger or Event Delivery, you can only verify that events are successfully making it from your source or to your destination. If events fail, you have to troubleshoot to see where in the pipeline your events are getting stuck. With Event Tester, you can verify that your event makes it from your source to your destination, but if the results aren't what you expected, you're stuck troubleshooting your source, filters, tracking plans, and destinations. 
 
 With Delivery Overview, you can verify that your source receives your events, that any filters and tracking plans work as expected, and that events successfully make it to your destination. Any errors or unexpected behavior can be identified using the pipeline view, leading to quicker resolution. 
 
 ## How can I configure alerts?

+You can also use Connections Alerting: a feature that allows Segment users to receive in-app, email, and Slack notifications related to the performance and throughput of an event-streaming connection.
+
+Connections Alerting allows you to create two different alerts:
+- **Source volume alerts**: These alerts notify you if your source ingests an abnormally small or large amount of data. For example, if you set a change percentage of 4%, you would be notified when your source ingests less than 96% or more than 104% of the typical event volume.
+- **Successful delivery rate alerts**: These alerts notify you if your destination's successful delivery rate falls outside of a percentage that you set. For example, if you set a percentage of 99%, you would be notified if you destination had a successful delivery rate of 98% or below.
+
+> info "Connections Alerting is in beta"
+> The Connections Alerting feature is in active development, and some functionality may change before it becomes generally available. During the beta, Connections Alerting supports event-streaming connections: [event streaming sources](/docs/connections/sources/#event-streams-sources) and [cloud-mode destinations](/docs/connections/destinations/#event-streams-destinations).
 
 ## Why is the Delivery Overview page only available for cloud-mode destinations? 
 Similar to Segment's [Event Delivery](/docs/connections/event-delivery/) feature, the Delivery Overview page is only available for server-side integrations (also known as cloud-mode destinations). You won't be able to use the Delivery Overview page for client side integrations (also known as device-mode destinations) because device-mode data is sent directly to the destination tool's API. In order to report on deliverability, data must be sent to destinations using a server-side connection.
