Create Monitoring Alerts Your Team Can Act On

Monitoring produces value when it helps someone understand a problem and take an appropriate action. A large collection of alerts can make that harder if routine noise competes with service failures. Begin with the journeys your business needs to keep working.

Describe the symptoms that matter

Identify critical actions such as opening a service page, signing in, submitting a request, or processing an order. Decide how the team will detect a failure in those journeys. Infrastructure measurements provide supporting context, but a healthy machine does not guarantee a successful customer task.

AWS reliability guidance covers monitoring resources, notifications, and response. Apply that principle by making each important alert answer three questions: what is affected, how urgent is it, and who should investigate?

Give the responder useful context

Include the affected environment, the time the issue began, a link to relevant evidence, and a short response guide. Avoid messages that contain only a metric name and a threshold. The responder should be able to identify the next safe check without searching through several unrelated dashboards.

For example, an alert about repeated request failures could link to a request log and the most recent deployment record. The guide might explain how to confirm user impact and when to involve another team. It should not encourage blind restarts without understanding the situation.

Match urgency to impact

Separate issues needing immediate attention from trends suitable for a planned review. Choose thresholds and observation windows based on workload behaviour, then adjust them using real incidents. Ensure scheduled maintenance has a documented treatment so expected changes do not create confusion.

Review the alerts after an incident

Ask which signal helped, which was missing, and which interrupted the team without adding information. Update the response guide while the details are fresh. A smaller, understood set of alerts can be more useful than a broad collection with no clear owner or response.
