This is to prevent the system from being affected when some monitoring metrics reach a certain value. You can set alarm rules for these monitoring metrics to enable the alarm system to automatically check the monitoring data and send an alarm notification to the administrator when the monitoring data meets the conditions. This helps you understand business exceptions the first time and resolve them quickly.
Background
Tencent Cloud Observability Platform (TCOP) is a real-time monitoring and alarm service for cloud product resources. TencentDB for CTSDB 3.0 provides alarms for monitoring metrics through TCOP. The alarm monitors some specific metrics within a certain period and sends alarm notifications by various methods (such as WeChat and SMS) every several time periods based on the given threshold. For more information, see Tencent Cloud Observability Platform(TCOP).
Billing Instructions
TCOP allows you to configure alarm policies to monitor key metrics of instances, which can be used for free.
Information about alarm notification objects has been collected, including emails, SMS, and phone calls.
