Datadog does something similar with the network performance monitoring option in their agent, it also uses eBPF. As a network engineer I've wanted tools like this for many years (say goodbye to tcpdump, in most cases), the data it produces is incredibly useful in a cloud environment where you typically do not get insights like this from the native toolset.
The history is that Datadog hired the Boundary people, who added this feature about 2 years ago.
(Boundary was a small SF startup that created a network flow product. Netflix evaluated it for use on Cassandra clusters. BMC acquired Boundary in 2015.)
