About the Alerts menu

To access the pages associated with the Alerts feature, go to Observability > Alerts. With the Alerts feature, you can receive automated notifications via various integrations when a metric you define either goes above or remains below a threshold.

The Alerts menu contains links to the following pages:

• Overview: where you can view a historical feed of alerts that are firing and that have been resolved.
• Definitions: where you can view and manage alert definitions. An alert definition is a configuration rule that defines when an alert should be triggered and how notifications should be handled.
• Integrations: where you can view and manage alert integrations. Alert integrations are external channels that receive notifications when alerts are triggered.

Before you begin

The Alerts feature is disabled by default and can be purchased by contacting sales@fastly.com. Once enabled, any user with the appropriate roles and permissions will be able to manage alerts for Fastly services and historic stats metrics.

Be sure you know how to access the web interface controls before learning about the information you'll encounter here.

About the Overview page

The Overview page contains a historical feed of alerts that are firing and that have been resolved. From this page, you can:

• view alerts that are firing by clicking the Alerts bell.
• filter the alert instances by service, alert definition name, and the time range when the alert was triggered or resolved.
• monitor alerts that are firing. An alert is firing when the condition set is no longer met during an evaluation period. Read about how alerts are triggered and resolved.
• view alerts with a Resolved status. An alert that was firing is considered resolved when the defined threshold is no longer being exceeded.
• click on a firing or resolved alert instance to access the details page for the alert. The alert details page displays a graph of the observed metric. On the graph, a horizontal black line marks the threshold, vertical red bars indicate when the metric went above or below the threshold, and vertical black lines indicate when a new service version was activated. The page also lists all firing and resolved instances of the alert. From the details page, you can edit the alert definition.

About the Definitions page

The Definitions page lists your alert definitions. From this page, you can:

• view alerts that are firing by clicking the Alerts bell.
• view a list of your alert definitions. You can use the Service menu to filter the list.
• create alert definitions.
• edit and delete existing alert definitions.

About the Integrations page

The Integrations page lists your alert integrations. From this page, you can:

• view alerts that are firing by clicking the Alerts bell.
• filter the alert integrations by type (e.g., Slack).
