Then go to website http://<server IP address>:5555 through browser and users can verify whether the Prometheus has been successfully installed. Since the RocketMQ-Exporter process has been started, the data of RocketMQ-Exporter can be retrieved by Prometheus at this time. At this time, users only need to change the Prometheus configuration file to set the collection target to the url address exposed by the RocketMQ Exporter. After changing the configuration file, restart the service. The content of prometheus.yml will be like as follows:
