HttpSender with Resilience4j Retry
HttpSender
is an interface for HTTP clients that are used in meter registries for HTTP-based metrics publication. There
are two implementations:
-
HttpUrlConnectionSender
:HttpURLConnection
-basedHttpSender
-
OkHttpSender
: OkHttp-basedHttpSender
Micrometer does not include support for retry, but you can decorate it with Resilience4j retry, as follows:
@Bean
public DatadogMeterRegistry datadogMeterRegistry(DatadogConfig datadogConfig, Clock clock) {
return DatadogMeterRegistry.builder(datadogConfig)
.clock(clock)
.httpClient(new RetryHttpClient())
.build();
}
private static class RetryHttpClient extends HttpUrlConnectionSender {
private final RetryConfig retryConfig = RetryConfig.custom()
.maxAttempts(2)
.waitDuration(Duration.ofSeconds(5))
.build();
private final Retry retry = Retry.of("datadog-metrics", this.retryConfig);
@Override
public Response send(Request request) {
CheckedFunction0<Response> retryableSupplier = Retry.decorateCheckedSupplier(
this.retry,
() -> super.send(request));
return Try.of(retryableSupplier).get();
}
}
