Tracing

An OpenTracing-compliant, simple, and extensible distributed tracing library.

  • Simple: add a single MonadTrace constraint to start tracing, without making your code harder to test!
  • Extensible: use the built-in Zipkin backend or hook in your own trace publication logic. 
import Monitor.Tracing

-- A traced action with its root span and two children.
run :: MonadTrace m => m ()
run = rootSpan alwaysSampled "root" $ do
  childSpan "child-a" runA
  childSpan "child-b" runB

To learn more, hop on over to Monitor.Tracing, or take a look at examples in the app/ folder.
