Since Java 11, an HttpClient
is provided as part of the JDK. See this introduction to it. Micrometer provides instrumentation of this via a micrometer-java11
module. This module requires Java 11 or later.
For Gradle, add the following implementation:
implementation 'io.micrometer:micrometer-java11'
For Maven, add the following dependency:
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-java11</artifactId>
</dependency>
Create an HttpClient
as you normally would. For example:
link:{include-micrometer-java11-test}/io/micrometer/java11/instrument/binder/jdk/MicrometerHttpClientTests.java[role=include]
You can instrument this HttpClient
as follows with an ObservationRegistry
:
link:{include-micrometer-java11-test}/io/micrometer/java11/instrument/binder/jdk/MicrometerHttpClientTests.java[role=include]
Alternatively, if you are not using an ObservationRegistry
, you can instrument with only a MeterRegistry
as follows:
link:{include-micrometer-java11-test}/io/micrometer/java11/instrument/binder/jdk/MicrometerHttpClientTests.java[role=include]
