# Tracing

An [OpenTracing](https://opentracing.io/)-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](http://zipkin.io) backend or hook in
  your own trace publication logic.

```haskell
import Monitor.Tracing

-- A traced action with its root span and two children.
run :: MonadTrace m => m ()
run = rootSpan (sampledEvery 10) do
  childSpan "part-a" runA
  childSpan "part-b" runB
```

[`Monitor.Tracing`](https://hackage.haskell.org/package/tracing/docs/Monitor-Tracing.html),
or take a look at examples in the `app/` folder.
