UPTIME MONITORING GUIDE
What Is Uptime Monitoring?
Uptime monitoring repeatedly requests a website or service endpoint to confirm that it is reachable. When checks fail, the monitor records the incident and alerts the responsible team.
What an uptime check measures
A basic HTTP check records whether a public URL returns a usable response and how long the request takes. Repeating the check creates an external history of availability and response time.
Why external checks matter
Internal services may report that they are running while customers cannot reach them because of DNS, certificates, networking, proxies, or failed dependencies. An external monitor observes the path a customer uses.
What uptime monitoring does not replace
Uptime checks identify symptoms, not root causes. Use application logs, infrastructure metrics, and traces alongside uptime monitoring to diagnose an incident.
Key takeaways
- ✓Monitor customer-visible URLs from outside your infrastructure.
- ✓Use consecutive failures to reduce transient false alarms.
- ✓Track recovery as well as initial downtime.
