Create and manage custom alert rules

Custom alert rules are suitable for scenarios where you need to define trigger conditions, alert severity, notification channels, and active periods. You can use PromQL to write condition expressions and receive alert messages through Notifier.

​

Create Custom Rules

1. Log in to the GPU Cloud console and go to the Alerts page.
2. On the Custom Rules tab, click New Rule.
3. Configure the rule in Basic Setting.

   Parameter	Description
   Rule Name	A custom rule name. We recommend using a name that reflects the alert target and trigger condition.
   Severity	The alert severity. You can select CRITICAL, WARNING, or INFO.
   Enabled	Whether to enable the rule after it is created.
   PromQL	A PromQL condition expression. After entering an expression, click Preview to view the expression result.
   Eval Interval Seconds	How frequently the rule checks the condition expression.
   For Duration Seconds	How long the condition must remain true before an alert is triggered.
   Notifier	The notification channel for sending messages after an alert is triggered. To send alert messages, select a previously created notifier.

4. Under Active Period, configure the effective dates and active times for the rule.

   Parameter	Description
   Effective Days	Select the days of the week when the rule takes effect.
   Active Times	Configure the time range during which the rule takes effect each day.

   To make the rule effective during multiple periods on the same day, click Add Period and continue configuration.
5. Click Confirm. After creation, verify that the rule is displayed and that its enabled status, trigger conditions, and Notifier meet expectations.
