Checkly is a monitoring system that sends alerts when it detects failures, but ensuring those alerts are delivered and noticed by the team can be challenging. To address this issue, Checkly offers strategies such as using group-level alert settings to enforce broader policies, utilizing multiple alert channels including email, Slack, SMS, and webhooks, verifying checks are working properly before sending notifications, and implementing soft assertions to reduce alert fatigue. By applying these best practices, teams can stay on top of problems and keep their systems running smoothly.
