ARMS sends alarms by email or SMS in real time when the configured alarm conditions are met.
Default alarm conditions:
- To avoid the explosive growth of alarm messages, if the same alarm goes off successively, a message about this situation is sent within 24 hours.
- If no duplicate alarm is generated within five minutes, ARMS sends a recovery email notifying you that the alarm has been cleared.
- After a recovery email is sent, the alarm status is reset. If this alarm goes off again, the alarm is deemed as a new one.
You can click query and delete distory in Alarm Management to query exceptions of a data record in a log at a specified historical time point.
In ARMS, alarm controls are essentially the data presentation of a dataset. Therefore, when you create an alarm control, ARMS also creates a dataset, which corresponds to the underlying data storage of the alarm control.
In the left-side navigation pane of the console, choose Custom Monitoring > Datasets, and query data in the target dataset, and get sample code of calling APIs.
- A custom monitoring job is required before you can create and setup an alarm control. For instructions on how to create a monitoring job, see Step 1 and Step 2.
- Before configuring alarms, set the contacts and contact groups. Alarm configuration only supports contact groups. You must set the contact groups after setting contacts.
