​QUIC and HTTP2 monitoring with DCRUM



Can we monitor the response time of web operation that using QUIC and HTTP2 with DCRUM?
If current DCRUM does not support these protocols, do you have a plan to support that?

HTTP2 is inherently using Diffie-Hellman encryption, and its spec allows only the Perfect Forward Secrecy encryption algorithms. This means that out-of-band decryption the way how DC RUM does it is not possible. So DC RUM directly does not provide insight into the HTTP2 content, nor there's a roadmap for that (because of technical feasibility). However, DC RUM can measure the TLS tier of the connection, including its availability and performance, which is very important because RUM (javascript agent injection) technologies don't measure this aspect.

So in reality, a RUM technology, like Dynatrace RUM, would bring user experience insight for HTTP2-delivered applications, while wire data monitoring technology, like DCRUM, would bring the app delivery channel (network, encryption, acceleration, load balancing) performance.

Regarding QUIC, it's UDP-based, so the RUM technology may still apply, but wire data insight would be limited to basically volumetric.
