Pixie (https://px.dev) can be installed in under 5 mins and gives this level of visibility across all applications. No need to change your application (wrap in `subtrace run`) to get instant visibility.

We also support 11 application protocols (https://docs.px.dev/reference/datatables/) with TLS handshake tracing and MQTT support coming soon (encrypted traffic tracing has been supported for a long time).

Subtrace already works great on Kubernetes (https://docs.subtrace.dev/kubernetes)! Add a single line to your image's Dockerfile and that's it.

I'm working on an even simpler way where you can just `kubectl apply` a DaemonSet or a Helm chart to get automatic tracing for all pods in your cluster instantly without any code-level changes. If anyone is interested in beta testing this, email me at [email protected], I'd love to understand your usecase!

Might be an overkill to use it in this capacity but SUSE NeuVector (https://github.com/neuvector/neuvector) can build a connectivity graph between pods and allows to perform packet capture to PCAP. It works at the virtual switch layer and can capture all traffic.
