Since I think there was another thread out there around tracing I'd thought I'd send out a few others for folks that show tracing being added to multiple other popular project (interesting to read over the proposals and such). - https://github.com/grpc/grpc/blob/master/src/core/ext/census/README.md#census---a-resource-measurement-and-tracing-system - https://github.com/kubernetes/kubernetes/issues/26507 (k8s tracing addition/proposal) - http://jaeger.readthedocs.io/en/latest/architecture/ It'd be real nice to finally get some kind of tracing support integrated into openstack; osprofiler was started a long time ago and I think it's due time for it to actually be used and integrated :) -Josh
