Class HttpForwardingMetricsConsumer

java.lang.Object

org.apache.storm.loadgen.HttpForwardingMetricsConsumer

All Implemented Interfaces:

IMetricsConsumer

public class HttpForwardingMetricsConsumer
extends Object
implements IMetricsConsumer

Listens for all metrics and POSTs them serialized to a configured URL.

To use, add this to your topology’s configuration: java conf.registerMetricsConsumer(HttpForwardingMetricsConsumer.class, "http://example.com:8080/metrics/my-topology/", 1);

The body of the post is data serialized using KryoValuesSerializer, with the data passed in as a list of [TaskInfo, Collection<DataPoint>]. More things may be appended to the end of the list in the future.

The values can be deserialized using the org.apache.storm.serialization.KryoValuesDeserializer, and a correct config + classpath.

@see org.apache.storm.serialization.KryoValuesSerializer
