Custom Alerts

Segment’s custom alerts allow you to customize the sensitivity of the trigger that activates an alert so you can more accurately detect event volume fluctuations in your integrations.

You can create alerts for the following product areas:

• Sources
• Destinations
• Reverse ETL
• Twilio Engage

Source volume alert

You can create an alert that notifies you when the volume of events received by your source in the last 24 hours changes beyond a percentage you set. For example, if you set a change percentage of 4% and your source received 100 events over the first 24 hours, Segment would notify you the following day if your source ingested fewer than 96 or more than 104 events.

To receive a source volume alert in a Slack channel, you must first create a Slack webhook. For more information about Slack webhooks, see the Sending messages using incoming webhooks documentation.

To create a source volume alert:

1. In your workspace, navigate to Connections, select Sources, and select the Event streams tab.
2. Select the event streams source you’d like to configure alerts for.
3. Select the Alerts tab and click Create alert.
4. On the Create alert sidesheet, enter a percentage of source volume change that you’d like to be notified for.
5. Select one or more of the following alert channels:
   • Email: Select this to receive notifications at the provided email address.
   • Slack: Select this to send alerts to one or more channels in your workspace.
   • In-app: Select this to receive notifications in the Segment app. To view your notifications, select the bell next to your user icon in the Segment app.
6. Click Save.

To make changes to a source volume alert, select the icon in the Actions column for the alert and click Edit.

To delete a source volume alert, select the icon in the Actions column for the alert and click Delete.

Successful delivery rate alert

You can create an alert that notifies you when the volume of events successfully received by your destination in the last 24 hours falls below a percentage you set. For example, if you set a percentage of 99%, Segment notifies you if your destination had a successful delivery rate of 98% or below.

To receive a successful delivery rate alert in a Slack channel, you must first create a Slack webhook. For more information about Slack webhooks, see the Sending messages using incoming webhooks documentation.

To create a successful delivery rate alert:

1. Navigate to the cloud-mode destinations you’d like to configure alerts for.
2. Select the Alerts tab and click Create alert.
3. On the Create alert sidesheet, enter a percentage. You will receive events if your successful delivery rate falls below this percentage.
4. Select one of the following alert channels:
   • Email: Select this to receive notifications at either the email address associated with your account or another email address that you enter into this field.
   • Slack: Select this and enter a Slack webhook URL and channel name to send alerts to a channel in your Slack workspace.
   • In-app: Select this to receive notifications in the Segment app. To view your notifications, select the bell next to your user icon in the Segment app.
5. Click Save.

To make changes to a successful delivery rate alert, select the icon in the Actions column for the alert and click Edit.

To delete a successful delivery rate alert, select the icon in the Actions column for the alert and click Delete.

Mapping-level successful delivery rate fluctuations

You can create an alert that notifies you when the volume of events successfully received by your mapping in the last 24 hours falls below a percentage you set. For example, if you set a percentage of 99%, Segment notifies you if your destination had a successful delivery rate of 98% or below.

To receive a successful delivery rate fluctuation alert in a Slack channel, you must first create a Slack webhook. For more information about Slack webhooks, see Slack’s Sending messages using incoming webhooks documentation.

To subscribe to alerts for successful delivery fluctuations at the mapping level:

1. Navigate to your intended mapping and select the Alerts tab.
2. Click Create alert.
3. Set an alert threshold, or the percentage of successfully delivered events that would prompt an alert.
4. Select one or more of the following notification channels:
   • Email: Enter an email address or alias that should receive alerts.
   • Slack notification: Enter a Webhook URL and a Slack channel name to receive alerts in a Slack channel.
   • In-app notifications: Select this to receive notifications in the Segment app. To view your notifications, select the bell next to your user icon in the Segment app.
5. Toggle the Enable alert setting on and click Create.

To edit or disable your alert, navigate to your mapping’s Alerts tab and select the Actions menu for the alert you’d like to edit.

Activation event health spikes or drops

You can create an Activation event health spikes or drops alert that notifies you when events sent from your audience to a downstream destination have failures to a destination above a certain threshold. For example, if you set a change percentage of 4% and your destination received 100 events from your Audience over the first 24 hours, Segment would notify you the following day if your destination ingested fewer than 96 or more than 104 events.

To create an Activation event health spikes or drops alert:

1. From your Segment workspace’s home page, navigate to Engage > Audiences.
2. Select the Audience you want to create an alert for, select the Alerts tab, and click Create alert.
3. On the Create alert sidesheet, select the destination for which you’d like to monitor event health.
4. Enter a percentage threshold to trigger activation event health notifications.
5. Select one or more of the following alert channels:
   • Email: Select this to receive notifications at the provided email address.
   • Slack: Select this to send alerts to one or more channels in your workspace.
   • In-app: Select this to receive notifications in the Segment app. To view your notifications, select the bell next to your user icon in the Segment app.
6. Click Save.

To make changes to an Activation event health spikes or drops alert, select the icon in the Actions column for the alert and click Edit.

To delete a Activation event health spikes or drops alert, select the icon in the Actions column for the alert and click Delete.
