# Cloud CDN analytics

> Interpret traffic, requests, cache performance, latency, geography, region, and protocol metrics.

Distribution analytics are available for the selected project and distribution.

## Time-series metrics

* Total, upstream, sent, and shield bytes.
* Total requests and 2xx, 3xx, 4xx, and 5xx responses.
* Cached and uncached responses.
* Request and traffic cache-hit rates.
* Upstream response time and overall request time when available.

## Breakdowns

| View | Dimensions |
| - | - |
| Geography | Country, traffic, requests, status classes, cache hits, and misses |
| Regions | Edge region, traffic, and requests |
| Protocols | Protocol, traffic, and requests |

## Investigation patterns

* A falling cache-hit rate with stable traffic suggests new URLs, cache-key fragmentation, short TTLs, or bypass behavior.
* Rising upstream time with stable edge request time can indicate origin degradation.
* A 4xx increase usually requires application, signed-URL, ACL, or path investigation.
* A 5xx increase alongside misses and origin latency points toward upstream health.

<Note>
  Analytics can return no content for a new distribution or an interval without collected traffic. Treat an empty response differently from a response containing zero-valued datapoints.
