The event center centralizes, stores, analyzes, and displays event data generated by Alibaba Cloud services. The event center supports the following events: change events of Enterprise Distributed Application Service (EDAS), alert events of Application Real-Time Monitoring Service (ARMS), 0-1 status events such as deadlocks, out of memory (OOM), and application startup failures, microservice governance events of Microservice Engine (MSE), and Kubernetes cluster events. If your application uses one of the related services, the event center automatically analyzes and displays the corresponding events in a unified manner. This provides an easy way for you to view and analyze the events.

Overview of the event center module
- Typical events: displays the number of typical events that are preset by the system. For more information, see Typical events.
- On the Normal View tab, all events associated with the current application are analyzed and displayed in multiple dimensions. For more information, see Normal view.
- On the Topology View tab, the events associated with the application and the resource topology of the application are displayed together. For more information, see Topology view.
- On the Subscription rules tab, subscription rules that you create are displayed in a list. For more information, see Subscription rules.
Typical events
Typical events: displays the number of times that each type of typical event preset by the system occurred within the last 30 minutes. You can adjust the time range in the upper-right corner. Click Subscribe below an event to edit subscription rules of the event. For more information about subscription rules, see Subscription rules.
Normal view
On the Normal View tab, you can specify filter conditions to search for events. The search results are displayed in four sections: Last two weeks event re li tu, Proportion of events from different sources, Trend of the number of events from different sources, and Event Details.

- The Last two weeks event re li tu section displays the heat map for hourly occurrences of events that meet the filter conditions in the last two weeks. A darker color indicates more events in the hour.
- The Proportion of events from different sources section displays the proportions of events from different sources.
- The Trend of the number of events from different sources section displays the trends of events from different sources within a specified period.
- The Event Details section displays details about all current events.
Perform the following operations to view information on the Normal View tab:
- In the Last two weeks event re li tu section, click each heat block to view event details in the hour.
- In the Trend of the number of events from different sources section, click each column to view all the events that occurred in the specified period in the Event Details section.
- In the Event Details section, click View in the Operation column to view the details of the event.
- In the Event Details section, click Subscription in the Operation column of an event to subscribe to the event. For more information, see Subscription rules.
Topology view
- Application-side events: the events in the event center.
- Events related to cloud resources: the events that CloudMonitor records.
- Audit related operations: the audit records from ActionTrail.
The topology view can help you troubleshoot the associated resources when an application error occurs. For example, in a large enterprise, an employee mistakenly restarts an ApsaraDB RDS instance in the production environment, which leads to an online service failure. The topology view helps you find out the restart operation on the ApsaraDB RDS instance that is accessed by the application.

Subscription rules
- Method 1: On the Subscription rules tab, click Create a subscription rule in the upper-right corner.
- Method 2: On the Normal View tab, click Subscription in the Operation column of an event in the Event Details section.

Troubleshooting
The issues that occur during the running of applications in Container Service for Kubernetes (ACK) clusters or serverless Kubernetes clusters deployed in EDAS are typically pod issues. For more information about the solutions, see Common pod errors.
