CloudMonitor provides multiple metrics, such as the used capacity and used connections, to help you monitor the status of ApsaraDB for Redis. After you create an ApsaraDB for Redis instance, CloudMonitor automatically collects data based on these metrics. CloudMonitor also allows you to set alert rules for these metrics so that you can receive alerts when any exception occurs.
