Which protocol is utilized for submitting metrics to Datadog?

The protocol utilized for submitting metrics to Datadog is HTTPS. This is important because HTTPS (Hypertext Transfer Protocol Secure) ensures that the data transmitted between the client and Datadog's servers is encrypted, providing a secure method for submitting sensitive metric data. It utilizes the security protocols SSL/TLS, which help in protecting the integrity and confidentiality of the information being sent.

Using HTTPS allows organizations to maintain the security of their data in transit, which is crucial in environments where data sensitivity is a priority. In the context of submitting metrics, it allows users to send metric data, event data, logs, and other telemetry information securely, contributing to robust data management practices.

While HTTP is a protocol for transmitting data, it does not provide the encryption that HTTPS offers, making it less secure for sensitive information. FTP, which stands for File Transfer Protocol, is not typically used for real-time metric submissions. Instead, it is more suited for transferring files rather than sending metrics continuously. TCP (Transmission Control Protocol) is a lower-level protocol that facilitates communication over a network but does not provide the specific HTTP request/response structure that Datadog requires.
