README.md

This is an example project showcasing the tracing of some popular libraries, currently wai, warp and http-client.

You can build and run it locally by executing the following:

$ stack --stack-yaml stack-8.8.2.yaml run -- megaexample +RTS -T -l -olmegaexample.eventlog

Now we can simulate a typical enterprise industrial workload of getting some data over HTTP and returning it over HTTP:

$ curl http://127.0.0.1:6502/http/example.com

Or even go deeper:

$ curl http://127.0.0.1:6502/http/localhost:6502/http/example.com

Or ask the service to perform a GC:

$ curl http://127.0.0.1:6502/gc

After stopping the megaexample service we can upload megaexample.eventlog (see the root level README for more examples):

eventlog-to-zipkin megaexample.eventlog
