Get edge and origin latency percentiles with country, colo and path breakdowns for the application.
GET
Network Performance
Returns edge and origin response-time percentiles (
Edge latency (
p50, p95, p99) for the application over a time window, plus per-country, per-colo and slowest-path breakdowns. Useful for diagnosing latency regressions and identifying which routes or regions are slowest.
Available only on Pro and Enterprise plans. Cache miss rate limit: 10 requests per 60 seconds per owner.

edge) measures time-to-first-byte at Cloudflare’s network; origin latency (origin) measures how long the application itself took to respond once the edge reached it. A gap between the two that grows during a window usually points at the application or its cluster node, while both rising together points at network conditions between the client and the edge.
This measures network latency, not container resource usage; for CPU, RAM, and bandwidth sampled from the container itself, see Get Application Metrics. Combine colos and countries with Network Analytics to see whether a slow region is also a low-traffic one before prioritizing a fix.
Parameters
