Tracing Stackage LTS Stackage Nightly Hackage Haskell CI

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 "parent" $ do
  childSpan "child-a" runA
  childSpan "child-b" runB
