CloudMonitor provides multiple metrics, such as the disk usage, inbound bandwidth, and outbound bandwidth, to help you monitor the status of HybridDB for MySQL. CloudMonitor also allows you to set alert rules for these metrics so that you can receive alerts when any exception occurs.

After you purchase HybridDB for MySQL, CloudMonitor automatically collects data based on these metrics.
