Overview
OpenTelemetry::Instrumentation::CrystalHttpClient
Instruments
- HTTP::Client
Reference: https://crystal-lang.org/api/1.4.1/HTTP/Client.html
The HTTP::Client auto-instrumentation redefactirs the HTTP::Client#io
method from a large method to a very small one,
and moves most of the work into two new methods, HTTP::Client#do_connect
and HTTP::Client#do_connect_ssl
, which can
then be instrumented, and can receive some additional code to capture some information which is normally discarded, but
which the semantic conventions for HTTP spans calls for. It then uses a #def_around_exec
block to complete the instrumentation.
