E-MapReduce:Create an event-triggered alert rule

Last Updated:Mar 26, 2026

Set up a system event-triggered alert rule in CloudMonitor to receive notifications when a specified event occurs in E-MapReduce (EMR).

After creating a rule, send a test event to confirm that notifications reach the intended recipients before relying on the rule in production.

Prerequisites

Before you begin, make sure you have:

Create a system event-triggered alert rule

To create a custom event-triggered alert rule instead, see Create a custom event-triggered alert rule.

  1. Log on to the CloudMonitor console.

  2. In the left-side navigation pane, choose Event Center > System Event.

  3. On the Event Monitoring tab, click Save as Alert Rule.

  4. In the Create/Modify Event-triggered Alert Rule panel, configure the following parameters and click OK. Leave other parameters at their default values. For the full parameter reference, see the Create a system event-triggered alert rule section of the Manage system event-triggered alert rules (old) topic.

    ParameterDescription
    Alert Rule NameA name for the alert rule
    Product TypeSelect E-MapReduce
    Event TypeThe type of event that triggers alerts
    Event LevelThe severity level of the event that triggers alerts
    Event NameThe name of the event that triggers alerts
    Alert Contact GroupThe contact group that receives alert notifications

Test a system event-triggered alert rule

Send a test event to confirm that alert notifications reach the intended recipients, or that events are pushed to the configured destination — an MNS queue, Function Compute function, Simple Log Service Logstore, or callback URL.

Testing is only supported for alert rules associated with a specific Alibaba Cloud service and a specific event.

  1. Log on to the CloudMonitor console.

  2. In the left-side navigation pane, choose Event Center > System Event.

  3. On the Event Monitoring tab, click Old Event Alarm Rules in the upper-right corner.

  4. Find the alert rule to test, click the more icon in the Actions column, and then click Test.

  5. In the Create Event Test panel, select the event to test.

  6. In the Content (JSON) section, edit the event content as needed — for example, update the instance ID.

  7. Click OK. CloudMonitor sends a test alert notification to the alert contact automatically.
