supporting tools for the IoTDB Enterprise Edition. It aims to solve the monitoring problems of IoTDB and its operating system, mainly including operating system resource monitoring, IoTDB performance monitoring, and hundreds of kernel monitoring indicators, in order to help users monitor the health status of the cluster, and perform cluster optimization and operation. This article will take common 3C3D clusters (3 Confignodes and 3 Datanodes) as examples to introduce how to enable the system monitoring module in an IoTDB instance and use Prometheus+Grafana to visualize the system monitoring indicators.</p><h2 id="installation-preparation" tabindex="-1"><a class="header-anchor" href="#installation-preparation"><span>Installation Preparation</span></a></h2><ol><li>Installing IoTDB: You need to first install IoTDB V1.0 or above Enterprise Edition.
