View alert events

This topic describes how to view details about an alert event and temporarily block an alert event.

Prerequisites

Make sure that you have the following permissions:

• Resource Permissions : Cluster Read-only, Tenant Read-only, OBProxy Read-only, Arbitration Service Read-only, Binlog Service Read-only, or Host Read-only permission
• Menu Permissions : Permission on the All menu of the Alert Center

Procedure

1. Log on to the OceanBase Cloud Platform (OCP) console.

2. In the left-side navigation pane, click Alert Center .

3. By default, the Alert Events tab appears.

4. Specify search criteria in the search area. All alert events that match the search criteria will be displayed in the Alert Events list.

   • You can search for an alert event by Application , Object Type , Alert Level , Keyword , Start Time , and End Time .

   • You can click Active Alerts and Alert History to switch between the alert lists.

   • You can click Export Alert Event to export all alert events that match the search criteria to your computer.

   • If alert pushes are configured for the alert event, you can click Failed in the Message Push column to view details about the alert event.

   • If no alert push is configured for the alert event, you can click Message Push Not Configured in the Message Push column to configure alert pushes for the alert event. For more information, see Create an alert push.

   • For an active alert event of the Log type that occurs only once and needs to be manually acknowledged, the Actions column provides two options: Resolved and Mask Alerts .

     • If the alert event has been resolved, you can click Resolved in the Actions column to clear the alert. After the alert is cleared, you cannot perform any operations on it.

     • If the alert event does not need to be concerned, you can click Mask Alerts in the Actions column to quickly block the alert message. Then the alert will not be reported before the block period expires. For more information, see Create a blocking condition.

   

5. Click the description in the Alert Description column of an alert event. The Details page of the alert event appears.

   1. In the Basic Information section, view the basic information of the alert event.

      • Click the name of an alert object to view its details.
      • Click the name of an alert rule to view its details. To modify an alert rule, click Edit Alert Rule on the details page of the rule. For more information, see Edit an alert rule.
      • Click Suggestions on How to Deal with Alerts to view the suggestions on handling the alert.

      

   2. In the Alert Event History section, view the alert event history and related information, including Alert Time, Alert Level , and Alert Status .

      

   3. View the alert notification history in the Alert Messages list.

      

   4. On the details page of the alert event, click Mask Alerts in the upper-right corner to block alert messages.

      Then the alert will not be reported before the block period expires.

   5. On the details page of the alert event, click Alert Analysis Data in the upper-right corner to download the logs related to alert analysis.

6. When many alert events are received, you can clear alert messages as needed.

   1. In the left-side navigation pane, choose System Management > Parameter Management .

   2. Search for the ocp.alarm.notification.expired-days parameter in the parameter list to set the retention period of alert messages, in days.

      After you specify this parameter, the alert messages and alert events that exceed the retention period will be deleted. The following data will be deleted upon expiration:

      • ocp2_alarm_notification
      • ocp_alarm_event_notification
      • ocp2_alarm_event_history
      • ocp_alarm_event_record
      • ocp2_alarm_filter (Cleared data will be written to ocp2_alarm_filter_history. The amount of rule information is small and therefore the rule history table does not need to be cleared.)

   Notice

   • We recommend that you set the alert clearing period to a proper value, for example, several months.
   • Alerts must not be left uncleared and unhandled for a long time. You can configure alert message push. We recommend that you promptly handle received alert messages.
