Class OkHttpMetricsEventListener

java.lang.Object
okhttp3.EventListener
io.micrometer.core.instrument.binder.okhttp3.OkHttpMetricsEventListener
@NonNullApi @NonNullFields public class OkHttpMetricsEventListener extends okhttp3.EventListener
EventListener for collecting metrics from OkHttpClient.

uri tag is usually limited to URI patterns to mitigate tag cardinality explosion but OkHttpClient doesn't provide URI patterns. We provide "URI_PATTERN" header to support uri tag or you can configure a URI mapper to provide your own tag values for uri tag.
