Summary
Closes #4962
The Java HttpClient reference page described how to instrument an
HttpClientbut didn't explain what tags are emitted by default or how to add/override them.Changes
Added a Customizing observations section to
docs/modules/ROOT/pages/reference/java-httpclient.adocwith:Default tags table — documents the four low-cardinality key values produced by
DefaultHttpClientObservationConvention(method,uri,status,outcome).Custom convention example — shows how to extend
DefaultHttpClientObservationConventionand overridegetLowCardinalityKeyValuesto add an extra tag.Builder usage example — shows how to register the custom convention via
MicrometerHttpClient.instrumentationBuilder().customObservationConvention(...).Test plan
./gradlew :docs:antora) and verify the new section renders correctly on the Java HttpClient reference page🤖 Generated with Claude Code
