Background information
OceanBase Migration Service (OMS) Community Edition monitors system events, such as the OMS Community Edition host failure, resource usage over thresholds, and downtime migration, and sends alerts to corresponding channels.
Procedure
Log on to the OMS Community Edition console.

On the Alerts page, click the System Alert Information tab.
By default, the System Alert Information page displays alerts of the last 7 days. In the upper-right corner of the page, you can select Last 7 Days , Last 3 Weeks, Last Month, or Last 3 Months from the drop-down list to view alerts within different ranges of time. You can also enter the alert ID or message content in the search box in the upper-right corner to search for an alert.
You can filter alerts by using the Alert Events and Sending Status columns on the System Alert Information page.
The following types of alert events are supported:
OMS Community Edition host failure.
Usage of resources on the OMS Community Edition host over thresholds.
OMS Community Edition downtime migration.
An alert can be in one of the following sending status:
Pending: The alert is waiting for its sending to be scheduled.
Failed: The alert failed to be sent to the destination channel due to network issues or other unknown reasons.
Successful: The alert is sent to the destination channel, such as OceanBase Cloud Platform (OCP).
Completed: If the alert is not triggered within 3 hours, the alert status becomes Completed.
Sent again: The alert is sent again because the last sending failed.
You can also click the host node of the alert to view details on the Server page.
