Default set of attributes for HttpClient instrumentation (trace and metric)

[vishweshbankwar]

The issue is to document the default set of attributes that will be part of initial stable release of trace and metric instrumentation library for HttpClient.

Traces

Following is the list of attributes are currently added by default:

• http.request.method
• http.request.method_original (if different from http.request.method [HttpClient & HttpWebRequest] Set http.request.method as per spec #5003)
• http.response.status_code
• network.protocol.version (Bug fix: [HttpClient] update network.protocol.version values as per specification #5006)
• server.port
• server.address
• error.type ([HttpClient] Add error.type for traces and metrics #5005)
• url.full

Following attributes will not be added by default and Enrich API can be used in case if these attributes are needed:

• network.peer.address
• network.peer.port
• http.request.resend_count

Metrics

For metrics(http.client.request.duration) all the required/recommended attributes will be added by default as per spec
