Application Real-Time Monitoring Service:Alert management module upgrade

Last Updated:Mar 11, 2026

The Application Real-Time Monitoring Service (ARMS) Alert Management module has been upgraded to separate notification logic from alert rules. Notifications are now managed through reusable notification policies, with added support for escalation, DingTalk group alerts, and external monitoring integrations.

Important

Existing alert rules continue to trigger and send notifications after the upgrade. However, notification settings on pre-upgrade alert rules become read-only. To modify them, migrate to a notification policy.

What changed

Concept mapping: before and after the upgrade

The upgrade restructures how alert rules relate to notifications. Previously, notification settings were configured directly on each alert rule. Now, notification policies are separate, reusable objects that decouple alert rules from notification logic.

Before the upgradeAfter the upgrade
Notification settings embedded in each alert rule (contacts, templates, silence period, validity period)Notification policies manage all notification settings separately
Alert templates used to create rules across applicationsApply a single alert rule to multiple applications (alert templates removed)
Default alert rules auto-created for Application Monitoring, Browser Monitoring, and Prometheus MonitoringDefault alert rules auto-created only for Prometheus Monitoring

Navigation changes

Before the upgradeAfter the upgrade
Alerts > Alert Policies (for Application Monitoring, Browser Monitoring, Custom Monitoring, and Prometheus Monitoring)Removed. Manage alert rules under each sub-service
Alerts > Alert RulesRemoved
N/AApplication Monitoring > Application Monitoring Alert Rules
N/ABrowser Monitoring > Browser Monitoring Alert Rules

Alert rules created in both the old and new Application Monitoring and Browser Monitoring sub-services are merged into the new pages.

Prometheus Monitoring alert rules

The old Prometheus Monitoring alert rule feature is still available but no longer maintained. To access it:

  1. In the left-side navigation pane, choose Prometheus Service > Prometheus Instances.

  2. Click the target cluster.

  3. In the cluster navigation pane, click Alert Rules.

  4. On the Prometheus Alert Rules page, click Back to Previous Version, and then click Create Alert Rule.

Note The old Prometheus Monitoring alert rule feature is deprecated. Use the new alert rule feature instead.

New capabilities

The upgraded Alert Management module introduces four capabilities:

FeatureDescription
Notification policyRoutes alert events to the right contacts through configurable dispatch rules, grouping, notification methods, and silence periods. Replaces per-rule notification settings from the previous version.
Escalation policyAutomatically escalates unresolved alerts to additional contacts after a specified period
DingTalk group notificationsSends alert notifications to DingTalk groups as interactive alert cards that support blocking and claiming alerts
IntegrationIntegrated with ARMS by default. Connects external monitoring services -- such as open source Prometheus, Simple Log Service (SLS), and CloudMonitor -- to ARMS Alert Management

Migrate notification settings

After the upgrade, notification settings on alert rules created in the old Alert Management sub-service are read-only. These settings include:

  • Alert contacts and contact groups

  • Notification templates

  • Alert clearance notifications

  • Intervals between repeated notifications

  • Validity period

Migration steps

  1. Open the alert rule for editing.

  2. Click Quick Migration to move the notification settings to the Notification Policy page.

  3. Review the migrated notification policy. The system sets some new parameters to default values -- verify that these defaults meet your requirements.

  4. Save the notification policy.

Important

After migration, the format and content of alert notifications may change. If you use DingTalk group chats with keyword filtering, make sure the notification content on the Notification Policy page includes the required keywords. Otherwise, DingTalk groups will not receive notifications.

View alert history for unmigrated rules

Alert events and notification records for old alert rules that are not associated with a notification policy cannot be viewed in the new Alert Management sub-service.

To view these records: choose Alert Management > Alarm Event History in the left-side navigation pane, and then click Previous Version.

How alert rules and notification policies work together

Alert rules and notification policies are loosely coupled. A single alert event can be handled by multiple notification policies, and a single notification policy can handle events from different alert rules. This decoupled design supports the following patterns:

  • Reuse one notification policy across many alert rules

  • Apply different notification strategies to the same alert rule through dispatch conditions

  • Route alert events automatically with fuzzy match in dispatch rules, without explicit rule-to-policy associations

Set up new alert rules

Create notification policies before creating alert rules. When you create a new alert rule, select an existing notification policy to handle its events.

Alternatively, create alert rules first without assigning a notification policy, and then configure dispatch rules with fuzzy match to automatically route matching alert events to the appropriate notification policy.

Removed features

FeatureReplacement

Alert Rules page (centralized)Alert rules pages under each sub-service
Alert template managementApply an alert rule to different applications directly
Default alert rules for Application Monitoring and Browser MonitoringCreate alert rules manually. Existing default rules continue to trigger. Prometheus Monitoring still auto-creates default alert rules.
