DeleteAlarm - Auto Scaling

Deletes an event-triggered task. If your business pattern is unpredictable or prone to unforeseen traffic spikes, you can create event-triggered tasks by associating CloudMonitor metrics to effectively monitor fluctuations in your business workload. Upon detecting that the criteria for alerts, as specified in event-triggered tasks, are fulfilled, Auto Scaling promptly issues alerts and executes the scaling rules predefined within those tasks. This process occurs within the predefined effective time windows of the tasks, thereby facilitating the automatic increase or decrease of Elastic Compute Service (ECS) instances or elastic container instances within your scaling groups. Ultimately, this mechanism ensures the dynamic optimization of resources based on real-time workload demands. If you no longer need an event-triggered task, you can call the DeleteAlarm operation to delete it.
