How does one define the TLS handshake time in HTTP monitoring?

Defining the TLS handshake time in HTTP monitoring involves understanding its role in the overall performance metrics. The correct choice highlights that TLS handshake time is indeed included in the total response time calculation for HTTP requests. This inclusion is crucial because the TLS handshake process establishes a secure connection before any actual data transfer takes place.

During the handshake, various steps occur, such as exchanging cryptographic keys and authenticating the server, which can significantly affect the user experience if the handshake time is lengthy. By accounting for this time in the total response time, monitoring tools provide a more comprehensive view of the performance and latency experienced by users. This insight allows teams to optimize and troubleshoot issues related to secure connections effectively.

While options such as measuring waiting time or server response time might seem relevant, they do not fully encompass the specific measurement of TLS handshake time in the context of total response time in HTTP monitoring. Understanding where TLS handshake time fits within overall performance metrics is essential for diagnosing and improving web application performance.
