Can I get the request and response body for each request made?

[ansjin]

Is there a way by which somehow i can get the request and response body for each request received and served by a service ?

@ansjin
What do you mean by "get the request body"? Do you mean before the appmetrics intervention?

If you mean after the intevention - depending on your framework (Koa for example), you could use something like the following
example.

If you mean before the appmetrics interventino -
you could basically fork appmetrics, and provide a callback to appmetrics to be used on each incoming / outgoing hook.
In this case, maybe appmetrics could also provide an "onBefore" style event.

@ansjin we don't currently collect this data in appmetrics-zipkin, or in appmetrics which is a more general monitoring tool. Do you want to add it to the Zipkin trace as metadata? I think that could be done although it's not something we have any plans to add to the tool so you would need to modify it yourself. https://github.com/RuntimeTools/appmetrics-zipkin/blob/master/probes/http-probe-zipkin.js#L98-L109 might be a good place to start.
