Earlier quoted context omitted.

VP of DeepFlow here. Thank you for your interest in DeepFlow! Yes, we have implemented distributed tracing using eBPF. In simple terms, we use thread-id, coroutine-id, and tcp-seq to automatically correlate all spans. Most importantly, we use eBPF to calculate a syscall-trace-id (without the need to propagate it between upstream and downstream), enabling automatic correlation of a service's ingress and egress request…

would it be reasonable to assume that because this entirely network-based, it would work best with systems which really emphasize the "micro" in microservices? how well does this work if, say, my system has a legacy monolith in addition to microservices?

I believe the current situation is like this.

The advantage of eBPF lies in *request granularity* (i.e. PRC, API, SQL, etc ...) distributed tracing. To trace the internal functions of an application, instrumentation is still required for coverage. Therefore, the finer the service decomposition, the more effective eBPF's distributed tracing becomes.

How are you different from Pixie?

The biggest difference: DeepFlow enables *Distributed* Tracing.

In addition, DeepFlow combines the capabilities of eBPF and cBPF to achieve full-stack tracing of syscall + network_forward. You can take a look at our documentation: https://deepflow.io/docs/about/features/
