The idea being tested is how much traffic is being handled by the CDN instead of the origin. The offload metric in the CDN records exactly that: the amount or percentage of requests that are served by the CDN rather than bouncing back to the origin. Because it directly tracks CDN usage, it’s the quickest way to spot changing traffic patterns and caching effectiveness early. If the offload metric rises, you’re mapping more traffic through the CDN, which usually means faster delivery and reduced load on the origin. If it drops, you may be seeing CDN cache misses or configuration issues, signaling a potential trend that could lead to performance changes soon.

Other metrics don’t capture this offload directly. The current cache hit ratio in the dispatcher.log shows how often the local dispatcher cache serves a request, not how much traffic is served by the CDN itself. Recent requests in AEM reflect overall request volume to the application, not the distribution between CDN vs origin. Output from the request.log measuring response time focuses on latency, not on the split between CDN-delivered and origin-delivered traffic.
