OpenTelemetry, Azure Function and AppInsights

The question has been raised about: how to do Distributed Tracing in Azure Function ?

And since December 2020, the PR that allow us to use AppInsights as backend has been merged (in 2.4.0 release).

For now, the best documentation is in this sample, that describes simple configuration.


  • upgrade your azure function durable extension to at least 2.4.0
  • enable distributed tracing through configuration in your host.json

Span can be found in AppInsights using Search for Requests and then clicking on any one.

Hope this helps !
