Manage alerts
Lindorm instances provide an instance monitoring feature. When a monitoring metric meets a specified alert condition, the contacts in an alert contact group receive a timely alert notification. This topic describes how to manage alert rules by using the Lindorm console.
Background information
The monitoring and alerting feature uses CloudMonitor. CloudMonitor allows you to configure monitoring metrics and alert rules. When an alert rule is triggered, CloudMonitor sends notifications by email or SMS to all contacts in the specified alert contact group. You can also manage alert contact groups for your monitoring metrics to ensure that relevant contacts receive timely alerts.
Create an alert rule
Log on to the Lindorm console.
In the upper-left corner of the page, select the region where the instance is deployed.
On the Instances page, click the ID of the target instance or click View Instance Details in the Actions column for the instance.
-
In the left-side navigation pane, click Configure Alert Rule to view the alert rules for the instance.
NoteAlert rules that you create in the Lindorm console are not displayed in the alert rule list of Cloud Monitor. To create alert rules by using the Cloud Monitor console, see View monitoring information.
This list shows information such as the rule name (for example, Lindorm Time Series Engine API Write Failure), category, and status. In the Actions column, you can view the rule's Alert History or perform operations such as Edit, Enable, Disable, and Delete.
