I am also glad to know that the merge between OpenTracing and OpenCensus is still going well. I started adding telemetry to the projects I maintain in my current job and so far it has been very helpful to detect not only bottlenecks in the operations but also sudden spikes in the network traffic since we depend on so many 3rd-party web API that we have no control over.
We often have to contact them to either investigate these problems because sometimes it seems we are faster to detect them than them, or explicitly fix bugs that we have detected thanks to our integrations. It has been an interesting experience for me specifically because up until a year ago I thought the services provided by the companies we have been integrating were very-VERY reliable, but not, these integrations have opened my eyes to the fragile state of HTTP, AWS networking, and the uncertainty of working with 3rd-party companies.
Thank you OpenCensus team for providing me with the tools to learn more.
