Description
Correlation of performance data for specific queries coming from several DNS servers can be hard. This talk discusses how we use tracing data in the vendor agnostic OpenTelemetry Trace format to provide trace information in a standard form. We show a visual representation of example traces and discuss a proposed EDNS0 extension to pass trace IDs between so correlation of trace data coming from multiple (chained) sources becomes easy and unambiguous.
Summary
Rough expected slidedeck content:
* short intro to OT
* some juicy screenshots of DNS resolution traces (like in https://github.com/PowerDNS/pdns/pull/15668 )
* a detailed view on some trace details
* protocol description for interoperability between different pieces of DNS software
