An IdGenerator
and Propagator
for hs-opentelemetry-sdk
that
generates and propagates TraceId
and SpanId
values that are compatible with
AWS X-Ray.
The API currently exposed by the hs-opentelemetry-sdk
package lacks a
convenient way to modify the TracerProviderOptions
(to tell it to use our
generator/propagator) as part of initialization. You basically have to
re-implement the internals of initializeTracerProvider
to do so.
While we plan to open a PR upstream to address the lack of API here, the workaround approach has at least been been encapsulated in a module of this library for convenience:
import OpenTelemetry.AWSXRay
import OpenTelemetry.Trace
import OpenTelemetry.Trace.Setup
import OpenTelemetry.Trace.Setup.Lens
main :: IO ()
main = do
withTracerProvider modifyTracerProviderOptions $ \tracerProvider -> do
let tracer = makeTracer tracerProvider "my-app" tracerOptions
-- do something with tracer
modifyTracerProviderOptions :: TracerProviderOptions -> TracerProviderOptions
modifyTracerProviderOptions =
idGeneratorL .~ awsXRayIdGenerator
. propagatorL <>~ awsXRayContextPropagator
This example uses lens, but you certainly don't have to.
