The OpenTelemetry framework has, next to log and metrics, signals for application tracing information. The ecosystem is geared towards webapplications, but is not exclusive to it. In this talk, I'll discuss how we added basic tracing support to PowerDNS, how we pass trace info to downstream servers via DNS, and what this looks like in Jeager. We did this without using the existing OpenTelemetry C++ SDK, so strap in for some code and protocol hijinks and get more familiar with OpenTelemetry Tracing in the process.
Pieter is a Senior Developer at PowerDNS, where he returned after 3 years of doing operations in the enterprise world. He's been interested in and involved with DNS for over 15 years. He can tell you that "it's always DNS" is a lie and DNS is innocent.
