Event monitoring covers service faults, operations and maintenance (O&M) events, and business exceptions. It provides event statistics by service, level, name, and application group to facilitate resource association and fault review. You can customize the recipients and methods of event notifications to prevent key events from being ignored. The event details help you locate faults.

System events

Event monitoring provides a centralized platform for you to query system events that are generated for different Alibaba Cloud services and view event statistics. This allows you to track the use of Alibaba Cloud services. After you group resources by using application groups, service-related system events are automatically associated with the resources in application groups. This helps you check various monitoring information in one place and troubleshoot issues.

Event monitoring also provides the event alert feature. You can configure alert rules based on the event level and receive event notifications by using emails, DingTalk chatbots, or alert callbacks. In this way, you can be notified of critical events immediately after they occur and handle the events in an automated online O&M process.

Event monitoring provides you with query and alert services for service faults and O&M events. For more information about the system events supported by CloudMonitor for Alibaba Cloud services, see Overview.

Custom events

Event monitoring allows you to report events, query events, and receive alerts about events. It allows you to report exceptions or important changes in your business to CloudMonitor and receive alerts when exceptions occur. The following figure shows how the custom event monitoring feature works.Custom event monitoring

Custom event monitoring and custom monitoring have the following differences:

  • Custom event monitoring focuses on the data of non-continuous events.
  • Custom monitoring focuses on periodically collected time series data.

Alert service and automated O&M

Event monitoring provides multiple alert methods for automated O&M.
Alert method Description
Alert notification You can receive alert notifications by using emails and DingTalk chatbots.
Message Service Events can be written to a queue in Message Service, which can then be connected to your own O&M system.
Function Compute Events can trigger Function Compute to process subsequent O&M logic.
Alert callback CloudMonitor can push alert notifications to your existing O&M system or message notification system by sending HTTP POST requests to an Internet URL that you provide. You can take actions based on received notifications.
