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.

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
