Hi, I'm very exited with KTor and I'm using it for several microservices. I created a Feature to integrate prometheus metrics on the http server. It was very easy. Then I created a Feature for the client side, but I got a little confused with the client pipelines and which is the best place to add the interceptor for measure total request time. I want to add to the measure the returned status code from the http response. Any help to understand pipelines and the proper place to inject metrics will be welcome. (edited)

Hi @Carlos Fau, Could you tell me if you want to measure time from first request byte to first response byte or from first request byte to last response byte?

Hi @e5l, I was wanting to measure until "last response byte", but if you can provide me both points I think no far in the future I will need to add the time to "first response byte"

HttpResponse and HttpRequest classes have requestTime and responseTime it will give you the metric for first case. You can use HttpSend interceptor to observe it.

Get second metric could be complex if the response is streaming. Could you tell me if you need streaming?

Not by the moment, so I can go with your info and in case in future I desperately need it I'll return to the channel.
Thanks a lot for your help
