MSE Event Center provides centralized management, analysis, and visualization of event data generated by Microservices Registry, Microservices Governance, and cloud-native gateways. You can configure event notifications and troubleshoot exception events based on the instructions provided in the MSE console.

Event model

An MSE event is defined by the following parameters.

Parameter

Description

Resource type

The type of the MSE resource for which the event is generated. Valid values:

  • Nacos

  • ZooKeeper

  • Application

  • Cloud-native Gateway

Resource name

The resource associated with the event. The displayed information varies by resource type.

  • Nacos and ZooKeeper: The instance name and instance ID.

  • Application: The namespace and application name.

  • Cloud-native Gateway: The gateway name and instance ID.

Event type

The type of the event. Valid values:

  • Exception

  • Scaling

  • InstanceMaintenance

  • InstanceChange

  • LosslessNotification

  • HighAvailability

  • Security

Event name

The name of the event, which consists of an event code and an event description.

Event level

The severity of the event, based on its impact.

  • INFO: Records a normal system operation or an expected user action that has no business impact.

  • WARN: Indicates a potential issue or a self-healed exception. This event may have a business impact and requires your attention.

  • CRITICAL: Indicates that the system has an exception that it cannot self-heal from, which disrupts business operations.

Time

The time at which the event is generated.

Event status

The status of the event. Valid values:

  • Completed

  • Executing

  • Succeeded

  • Failed

Initiator

The initiator of the event.

  • You can use the console or API operations to trigger events. If you trigger events by using an Alibaba Cloud account, root is displayed. If you trigger events as a RAM user, the ID of the RAM user is displayed. If you trigger events by using a role, the role name is displayed.

  • If an event is generated when the system performs automatic O&M or periodically runs system tasks or when O&M engineers initiate operations in the O&M system, SYSTEM is displayed.

  • Governance rules: Displays the rule type and rule ID, such as Rule Type (Rule ID). You can click the rule type to navigate to the governance rule page.

Event content

The content of the event.

Go to the Event Center page

  1. Log on to the MSE console.

  2. In the navigation pane on the left, choose Event Center.

Query events

You can query events by the following dimensions:

  • Resource type

  • Event type, event name, event severity, or event status

  • Event trigger time

Query events by resource type

Select a resource type to filter events.

When you select Nacos, ZooKeeper, or Cloud-native Gateway, you can perform a fuzzy search by resource ID or resource name.

When you select Application, you can filter by Namespaces and perform a fuzzy search by application name.

Query events by event type, event name, event severity, or event status

Click the image.png icon next to Event type, event name, event level, or event status to filter the events.

The filter options for event type include HighAvailability, InstanceMaintenance, Scaling, Exception, Security, LosslessNotification, and InstanceChange. Select the options you need and click OK to apply the filter.

Query events by trigger time

Select a time range to filter events by trigger time.

Note

You can query events from up to the last 30 days on the Event Center page.

View the details of an event

Click Details in the Actions column of an event record to view its details. For some exception events, you can follow the suggestions provided on the Details page to take the next step and eliminate the risk.

Use the quick query feature

For Nacos, ZooKeeper, or Cloud-native Gateway resources, you can query events directly from the resource management page. The following example shows how to query events for a cloud-native gateway.

  1. Log on to the MSE Gateway Management console.

  2. In the navigation pane on the left, choose Cloud-native Gateway > Gateways.

  3. On the Gateways page, find the target gateway and choose More > Query Events in the Actions column.
