There are many alternatives for distributed tracing like Lightstep, Jaeger and so on but the ambitious level of integration with log searching (like ELK) and payload tracking is like an integrated in-house Splunk. Great idea and great to see the energy and enthusiasm put into making debugging tools better! One dream feature for a tool like this: code execution counts showing which version of the code and even which lines were executed - in aggregate is useful but ideally for each trace.

Unfortunately, the tradeoff of value gained saving debugging time against cost of infrastructure and development is hard to manage. The storage costs are very easy to measure so it is tempting to go after them rather than the more intangible benefits that rely on a counterfactual of how hard things would be to debug without it.
