Frequently Asked Questions
How does the geographic monitoring work?
We run probes from 6 regions worldwide (US-East, US-West, EU-West, AP-South, AP-East, SA-East). Each probe hits your endpoint on your configured schedule and records latency, status code, and timestamp.
What does the heatmap actually show?
The heatmap plots response time buckets (fast/ok/slow/critical) across regions (Y-axis) and hours of the day in UTC (X-axis). Color intensity reveals patterns — like an endpoint that degrades every morning in Asia-Pacific.
Can I monitor private or internal APIs?
Yes. You can whitelist our probe IP ranges in your firewall or VPN, or use our lightweight agent that runs inside your network and pushes metrics to our dashboard.
