Micrometer: Support to get http response size by micrometer

[dipindas]

Please add support to get http response size as a metric value

[jkschneider]

Thanks. Surprised we didn't think of that earlier. Will do it with a DistributionSummary so you can best understand the distribution of response sizes over time.

Just requires a change to WebMvcMetricsFilter, _et al_ and making the corresponding change in Spring Boot 2 and other web frameworks.

Just out of curiosity, would this include body-only-size or include the headers as well?

[shakuzen]

@mweirauch I think we should do both body and headers (with a tag?) as much as possible. Also, a separate metric for request and response sizes would be potentially useful.

[mweirauch]

Sounds good.
Would we be differentiating between server and client side instrumentation? Guess so.
So in analogy to http.server.requests and http.client.requests:
http.server.request.size and http.client.request.size? (Don't pin me on the naming.)

http.server.request.size and http.client.request.size? (Don't pin me on the naming.)

@mweirauch I guess you meant http.server.response.size and http.client.response.size?

[mweirauch]

Eek, things go wrong when doing stuff in between. What I meant was ...
http.server.[request,response].size for server (webmvc,jersey,webflux) instrumentation
and
http.client.[request,response].size for client (RestTemplate, okhttp?,...) instrumentation
