Modify the `metricsExporterType` within the `brokerConfig` to `PROM`, which will export data in Prometheus format. ... ```java private MetricsExporterType metricsExporterType = MetricsExporterType.PROM; ... private int metricsPromExporterPort = 5557; private String metricsPromExporterHost = "127.0.0.1"; ... ``` 2. Initiate both the broker and nameserver processes. 3. Execute the following command in the local terminal: `curl localhost:<export_port>` (default is `5557`), then verify that the output metrics align with expectations. -- This is an automated message from the Apache Git Service.
