This idea is quite popular in distributed / cloud systems nowadays, and there are tons of open source projects. Every cloud vendor has a product that does it (AWS X-Ray, Google Stackdriver Trace, etc), and there are plenty of open source products (Jaeger, OpenTracing), as well as third party vendors (we're using Datadog ourselves). Having said that, I completely agree with this being very important, and it is the backbone of our ability to debug issues. I would add that it is important to have the ability to correlate things as well, specifically your logs and traces ("give me all the logs that relate to this trace X").
