Pixie contributor here. Lots of great eBPF resources there!

For the question of whether it's possible to trace conditionally when a pattern expression matches, Pixie's philosophy is to trace everything and then allow you to use the querying language (called PxL) to query for the conditions you were looking for. The idea is that you may not know what you should have been looking for until you need to troubleshoot.

To be able to drop into an (e.g. rr) debugger on condition (e.g. by replicating that node's state ~State Share ) might result in a less appropriately comprehensive automated test suite, or faster tests?

Looks like Jaeger (Uber contributed to CNCF) supports OpenTracing, OpenTelemetry, and exporting stats for Prometheus. https://github.com/cncf/landscape
