CloudMonitor provides multiple metrics, such as the cluster status, cluster queries per second (QPS), and cluster write QPS, to help you monitor the status of Elasticsearch. CloudMonitor also allows you to set alert rules for these metrics so that you can receive alerts when any exception occurs.

After you purchase Elasticsearch, CloudMonitor automatically collects data based on these metrics.
