ERROR to write metric to graphite

[anhtv08]

hi,
I am currently setup a local kafka cluster, and use kafka Graphite to consolidate the metrics produced by brokers. However I got following issues.

2017-02-04 00:28:09,593] WARN Error writing to Graphite: Connection refused (Connection refused) (com.yammer.metrics.reporting.GraphiteReporter)

Below are configuration:

kafka.metrics.reporters=com.criteo.kafka.KafkaGraphiteMetricsReporter
kafka.graphite.metrics.reporter.enabled=true
kafka.graphite.metrics.host=localhost
kafka.graphite.metrics.port=8888

Please help to figure out what went wrong?
Note: I am using Kafka 0.10 I am not sure current one working with the latest kafka

Are you sure the port is correct? 8888 is not the standard port for graphite, it is 2003
