Uptime Monitoring: Checks, Alerts, and False Positives
DEV Community
EDITOR BRIEF
Uptime monitoring checks on a schedule whether a service is responding correctly and alerts someone when it is not. The excerpt explains HTTP, keyword, heartbeat, and TCP checks, and why a single failed check usually should not count as an outage. It also stresses using confirmation windows so brief blips do not create noisy, ignored alerts.
INSIGHTS
If you build services, learning how monitors decide “down” vs. “up” helps you design better alerts. Try setting up a simple check and requiring consecutive failures before paging anyone.
