Stream Collector StatsD Monitoring not working

I have an instance of Snowplow Stream Collector OSS 3.0.0 running on my EKS cluster. My Events are showing up fine sending to Kinesis. However, I am unable to get the monitoring components to send stats to statsD. My config looks like

monitoring {                                                                                                                                                                   
     metrics {                                                                                                                                                                    
        statsd {
            enabled = true
            hostname = datadog.datadog.svc.cluster.local
            port = 8125
            period = 10.seconds
            prefix = snowplow.collector
       }
    }                                                                                                                                                                            
}

What else am I missing ?
