Record prefilter bytes received from network/cache/total |
||
Issue descriptionIn order to understand the impact of the HTTP Cache, it's important to understand the network bytes it saves relative to total bytes. As such, record new UMA for per-request bytes received, bytes received from cache, and bytes received from network. The sums of these metrics can be used to understand the network savings of the cache.
