successFunction

public MetricCollectingServiceBuilder successFunction(BiPredicate<? super RequestContext,? super RequestLog> successFunction)

Description copied from class: AbstractMetricCollectingBuilder

Defines a custom BiPredicate to allow custom definition of successful responses. In other words, specify which responses should increment metrics.success() and which - metrics.failure().

Example:

     MetricCollectingService
         .builder(MeterIdPrefixFunction.ofDefault("hello"))
         .successFunction((context, log) -> {
             final int statusCode = log.responseHeaders().status().code();
             return (statusCode >= 200 && statusCode < 400) || statusCode == 404;
         })
         .newDecorator();
