As part of our [Observability product offerings](https://docs.fastly.com/products/product-observability), Fastly provides you with a collection of features that allow you to continuously monitor the status of your website, product, or service using real-time and historical metrics.

- **Alerts.** The [Alerts feature](https://www.fastly.com/documentation/guides/observability/alerts/about-alerts) provides visibility into service health conditions via automated notifications for service-related performance metrics. You can set up alerts via the web interface or the API to receive notifications to various integrations when a metric you define either goes above or remains below a threshold.
- **Domain Inspector.** Our [Domain Inspector interface](https://www.fastly.com/documentation/guides/observability/observability-dashboards/about-the-domains-page) feature (available for Delivery only) offers a dashboard designed to provide you with real-time and historic visibility into response data for traffic from your domains and subdomains to a Fastly Deliver service. It allows you to monitor traffic for a [fully qualified domain name](https://en.wikipedia.org/wiki/Fully_qualified_domain_name) without requiring you to send log data to a [third-party data collector](https://www.fastly.com/documentation/guides/integrations/logging-endpoints).
- **Edge Observer.** Our [Edge Observer interface](https://www.fastly.com/documentation/guides/observability/about-observability/about-the-observability-pages) serves as the entry point of all our Observability features. It provides you with customizable views that give insights into key metrics that can inform your decisions and goals.
- **Log Explorer & Insights.** The [Log Explorer & Insights feature](https://docs.fastly.com/products/log-explorer-and-insights) offers a dashboard designed to provide you with visibility into edge request performance. It allows you to monitor and analyze request traffic, detect error patterns, and help identify performance issues with your web properties.
- **Origin Inspector.** Our [Origin Inspector interface](https://www.fastly.com/documentation/guides/observability/observability-dashboards/about-the-origins-page) offers a dashboard designed to provide you with real-time and historical visibility into responses delivered from your origin servers to the Fastly Edge Cloud. It allows you to monitor origin traffic without requiring you to send log data to a third-party data collector.
