Checking AOM Alarms or Events

Function Introduction

• The alarm list provides the following key functions:
  • Alarm list: Check alarm information by alarm severity in a graph.
  • Advanced filtering: Filter alarms by alarm severity, source, or keyword in the search box. By default, alarms are filtered by alarm severity.
  • Alarm clearance: Clear alarms one by one or in batches.
  • Alarm details: Check the alarm object and handling suggestions in the alarm details. Handling suggestions are provided for all alarms.
• The event list provides the following key functions:
  • Event list: Check event information by event severity in a graph.
  • Advanced filtering: Filter events by event severity, source, or keyword in the search box. By default, events are filtered by event severity.

Constraints

• The alarms triggered by metric alarm rules last for five days by default. After five days, they will be automatically cleared and become historical alarms.
• When you go to the the alarm list page, a dialog box is displayed, asking you whether to enable alarm rule execution recording. You can directly enable it or go to the global settings page to enable it. If this function is enabled, execution records of Prometheus and log monitoring alarm rules will be reported to the alarm-execution-history log stream under the lts-system log group. You can view the historical execution conditions of alarm rules, alarm trigger status, and notification status, content, and channels. This may generate some fees. For details about LTS billing, see Billing Items. If you do not need to view alarm rule execution records, select Do not show again.

You can also view the bound alarm notification rule or alarm noise reduction rule if there is any. On the Alarm Info tab page, click the original rule name, log group name, or log stream name in blue to check more details. Alarms whose source is LTS: Click a log group, log stream, keyword, or query statement on the alarm details page to obtain more information. Alarms triggered by the alarm rules bound to Prometheus instances for CCE: Click a cluster name, node, pod, or container on the alarm details page to go to the built-in dashboard to query metric curves at different time. Alarms triggered by APM alarm rules: Click an application, component, or environment on the alarm details page to obtain more information. On the Alarm Info tab page, click a custom attribute and choose Copy or Add to Search. Copy: Copy the custom attribute. Add to Search: Filter alarms by custom attribute in the search box on the Alarm List page.
   Checking event details	Click the event name to view the event details.
   Checking cleared alarms	Click Active Alarms and select Historical Alarms from the drop-down list to check alarms that have been cleared.
   Checking the details and execution records of an alarm rule	On the Alarms tab page, check the alarm rule details and execution records of the active alarms whose sources are LTS and AOM. (The Events tab page does not provide the alarm rule details or execution records.) Click View Execution Record in the Operation column of the target alarm rule. On the Alarm Rule Details page, switch to the Current Rule tab to check the current alarm rule. Click View Execution Record in the Operation column of the target alarm rule. On the Alarm Rule Details page, switch to the Execution Records tab to check parameters such as Trigger Result, Notification Status, and Notification Type. To view alarm rule execution records, you need to enable Alarm Rule Execution Recording. For details, see Configuring Alarm Rule Execution Recording. You can query alarm rule execution records in the last 30 minutes, last hour, last 6 hours, last day, last week, last 30 days, or a custom period. You can search for alarm rule execution records by alarm group ID, trigger result, description, alarm execution record ID, or alarm rule ID. If the notification function is configured for AOM metric alarm rules or APM alarm rules, only the notification content sent for the first time will be recorded. Duplicate alarm and notification details will not be recorded. If an alarm notification is sent through voice calls, FunctionGraph (functions), or WeLink, the notification content cannot be viewed. If Recipient is set to Notification Group during alarm notification configuration and an alarm notification is triggered later, the notification status displayed on the Execution Records page is No subscription. (Notification groups depend on Cloud Eye. AOM cannot obtain the notification status.)
