edit:

I found one more https://www.envoyproxy.io/docs/envoy/latest/configuration/cluster_manager/cluster_stats.html#alternate-tree-dynamic-http-statistics

Those resolve to the same as https://www.envoyproxy.io/docs/envoy/latest/configuration/cluster_manager/cluster_stats.html#dynamic-http-statistics
