We are going to add instrumentation support for #OpenTelemetry to #Fedify. What kind of spans or events would you like to be instrumented?

@opentelemetry instruments are being added one by one to #Fedify…!

Instrumented spans

Fedify automatically instruments the following operations with OpenTelemetry spans:

Operation Span type Description
Federation.fetch() Server Serves the incoming HTTP request.
lookupObject() Client Looks up the Activity Streams object.
lookupWebFinger() Client Looks up the WebFinger resource.
handleWebFinger() Server Handles the WebFinger request.

More operations will be instrumented in the future releases. — ALT text

@fedify this is super cool! From the top of my head, it would be useful to track time spent in queues, all the remote calls (like resolving JSON-LD stuff, or resolving references) and auth checks.
