Hi, ATS 7.1.2, parent routing enabled. Everything goes through parent except one test url request that has very small response size (20 bytes).
To calculate ATS cache byte hit ratio, I'm using following metrics: "proxy.node.http.user_agent_total_response_bytes": "363046018479", "proxy.node.http.origin_server_total_response_bytes": "359470059035", "proxy.node.http.parent_proxy_total_response_bytes": "356244228124", I wonder how is it possible that (parent_proxy_total_response_bytes + origin_server_total_response_bytes) is bigger than user_agent_total_response_bytes? Everything going to user agent (client) must come from either local cache or from parent or from origin. This looks like stats bug to me. Maybe even fixed in some newer ATS version? According to my understanding, only those responses coming directly from origin should be included in proxy.node.http.origin_server_total_response_bytes and only responses coming from parent should be included in proxy.node.http.parent_proxy_total_response_bytes. Best regards, Veiko
