Tracing Your Code
In the previous chapters, we talked about instrumentation libraries and learned how to use auto-collected telemetry to monitor and debug distributed systems. Auto-instrumentations, when available, provide necessary and reasonable coverage for network calls, but you may want to trace additional logical operations, I/Os, sockets, or other calls that don’t have shared instrumentation available.
This chapter provides an in-depth guide to manual tracing using the System.Diagnostics primitives or the OpenTelemetry API and explains the mechanism behind auto-instrumentation. We will cover the Activity properties and how to populate them and show you how to record events. We’ll then learn how to use links to represent complex relationships ...
