Alarm Management
The ES Serverless service supports alarm management, allowing you to configure alarm policies for specific objects in the console. These policies periodically perform retrieval and analysis on indexes within monitored objects. When query results meet trigger conditions, an alarm notification is sent (currently supported via email and WeCom), enabling timely detection of issues. This feature supports keyword alarms, such as the number of the term error within logs over a specified time range, and metric monitoring, such as determining whether the maximum value of a numeric field exceeds a set threshold within a specified time range. This capability enhances observability in log analysis scenarios, enabling quick issue detection and resolution.
