Application Real-Time Monitoring Service:Create and manage alert rule templates

How it works

1. Create a template -- Define alert conditions using a preset metric (static threshold) or a custom PromQL expression.

2. Apply the template -- Select one or more Prometheus instances and deploy the template to generate alert rules on each.

3. Manage at scale -- Update, enable, disable, or delete generated alert rules in bulk from the template.

Each template maintains a mapping to the alert rules it creates. This mapping controls how updates and deletions propagate:

Prerequisites

Before you begin, make sure that you have:

• An Alibaba Cloud account with access to Application Real-Time Monitoring Service (ARMS)

• At least one Prometheus instance in Managed Service for Prometheus

• An alert contact group configured in ARMS

Create a template

1. Log on to the ARMS console.

2. In the left-side navigation pane, choose Managed Service for Prometheus > Prometheus Alert Rule Templates.

3. On the Prometheus Alert Rule Templates page, click Create Prometheus Alert Rule Template.

4. Set Check Type to one of the following:

   • Static Threshold -- Select a preset alert metric and define threshold-based conditions. Best for standard infrastructure metrics such as CPU utilization, memory usage, or disk capacity.

   • Custom PromQL -- Write a PromQL expression to monitor any metric, including those not available as presets. Best for multi-metric conditions or custom application metrics.

   

5. Configure the template parameters. See Static threshold parameters or Custom PromQL parameters.

6. Click OK.

Apply a template to Prometheus instances

After you create a template, apply it to one or more Prometheus instances to generate alert rules automatically.

1. On the Prometheus Alert Rule Templates page, find the template and click Apply Template in the Actions column.

2. In the Application Template dialog box, on the Prometheus Instance Selection Mode tab, select one or more Prometheus instances and click OK.

   Note

   Filter instances by name, region, or type.

3. Choose whether to update existing alert rules and click OK.

   ARMS uses the current template to create an alert rule for each selected Prometheus instance.

   • If you clear Update Created Alert Rules, any rules previously created from this template remain unchanged. The console displays: The alert rules are not updated because they are created from this template.

   • If you select Update Created Alert Rules, existing rules created from this template are overwritten with the current template settings.

   Important

   If a rule was manually modified but still mapped to this template, selecting Update Created Alert Rules overwrites those modifications. To prevent this, remove the mapping when you edit the rule. See How it works for details on template-rule mapping.

View and manage rules created from a template

1. On the Prometheus Alert Rule Templates page, find the template and click View Alert Rules in the Actions column.

2. In the Alert Rules Created from Template dialog box, manage rules as needed:

   • Enable rules -- Select one or more rules and click Enable Alert Rules.

   • Disable rules -- Select one or more rules and click Disable Alert Rules.

   • Delete rules -- Select one or more rules and click Delete Alert Rules.

Delete a template

1. On the Prometheus Alert Rule Templates page, find the template and click Delete in the Actions column.

2. Choose whether to delete the associated alert rules and click OK.

   • If you select Delete Alert Rules Created from Template, all rules generated from this template are deleted. Rules that were previously unmapped (by selecting Remove the mapping between this alert rule and the alert rule template during an edit) are not affected.

   • If you clear Delete Alert Rules Created from Template, all generated rules are retained as standalone rules.
