Instana.Wai.Middleware.Entry

Automatically creates entry spans for all incoming HTTP requests in a WAI application. It will also add (or append to) the HTTP respons header (Server-Timing) that is used for website monitoring back end correlation.

Note that exit spans still need to be created manually via the withExit or startExit/stopExit functions.

Example

main = do
  Warp.run 3000 $ InstanaWaiMiddleware.traceHttpEntries instana $ app
