Customers experience an application from outside its infrastructure. They need pages to load, APIs to respond, certificates to remain valid, and service updates to be clear during an incident.
Vigilmon helps teams watch those customer-facing signals from multiple locations. It is designed for public URLs, TCP endpoints, and certificate-expiry checks.
What to monitor
Start with the paths and endpoints that users rely on:
- The main application URL and sign-in flow
- Public API health endpoints
- Critical TCP services
- TLS certificate expiry dates
- A status page that communicates known incidents
Each monitor should have a clear owner, a meaningful response-time expectation, and an alert channel that reaches the people who can act.
Reduce noisy alerts
A single failed check can be caused by a temporary routing, DNS, or regional network problem. Vigilmon uses multi-region consensus before treating a failure as an outage. This gives responders a stronger signal and avoids waking a team for isolated probe failures.
When an outage is confirmed, notify the right channel, update the status page, and preserve the event timeline for follow-up. After recovery, review the incident and decide whether another monitor or alert threshold would improve detection.
A practical starting point
Create monitors for your home page, one representative API request, and any endpoint used for payments, authentication, or customer onboarding. Choose a cadence that matches the service's impact, then add a second region for the services where false positives would be especially costly.
External availability monitoring complements application logs, metrics, and traces by answering a different question: can customers reach the service now?
