Java 8 Metric writers, exporters and aggregation Example: Export to Redis Example: Export to Open TSDB Example: Export to Statsd Example: Export to JMX Aggregating metrics from multiple sources Dropwizard recommendations. ## Example: Export to Open TSDB If you provide a @Bean of type OpenTsdbHttpMetricWriter and mark it @ExportMetricWriter metrics are exported to Open TSDB for aggregation. The OpenTsdbHttpMetricWriter OpenTsdbHttpMetricWriter has a url property that you need to set to the Open TSDB "/put" endpoint, e.g. localhost:4242/api/put). It also has a namingStrategy that you can customize or configure to make the metrics
