Which metric is NOT included in the calculation of HTTP monitor response time?

The metric that is not included in the calculation of HTTP monitor response time is network latency. HTTP monitor response time specifically focuses on the time taken to process a request and retrieve a response from a server, which encompasses several components such as DNS lookup time, TCP connect time, and TLS handshake time if applicable.

Network latency, however, refers to the delay in the transmission of packets over the network and is typically measured separately from the actual HTTP transaction components. While it certainly affects overall communication speed, it doesn't directly factor into the specific calculation methodology for HTTP monitor response time as defined within the metrics used for monitoring HTTP requests. The HTTP response time metrics are more concerned with the individual steps of establishing a connection and retrieving content from the server rather than the broader aspect of network conditions affecting transmission delays.
