Uptime Monitoring Explained: HTTP, Heartbeat, TCP Checks and Reducing False Alerts

Uptime monitoring involves periodically checking whether a service is responding correctly and alerting teams when it is not, with the aim of detecting problems before customers do. Common check types include HTTP, keyword, heartbeat, and TCP, each suited to different infrastructure components such as websites, APIs, cron jobs, and databases. A major source of alert fatigue is treating a single failed check as an outage; requiring consecutive failures before triggering an incident helps filter out transient network blips. Checking from multiple geographic regions adds another layer of accuracy, since a network issue in one location can otherwise be mistaken for a genuine service outage. Tying confirmed monitor states to a public status page ensures customers receive accurate, real-time information without requiring manual updates.
