Microservices Engine:Manage alert rules

Last Updated:Nov 15, 2023

The cloud-native gateways of Microservices Engine (MSE) provide the alerting feature based on Application Real-Time Monitoring Service (ARMS). If alert rules are matched, MSE sends alert notifications to you by using emails, text messages, or DingTalk in real time. This helps you identify errors at the earliest opportunity. On the Alerts page, you can manage custom alert rules of your account and query the history of alert events and alert notifications.


A contact group is created. For more information, see the Create a contact group section in the "Manage alert contacts" topic.

Background information

An alert control is a method to display data in datasets. When you create an alert control, a dataset is also created to store the underlying data of the alert control.


New alerts take effect within 10 minutes. A delay of 1 to 3 minutes may exist when MSE checks alerts.

Create an alert rule

  1. Log on to the MSE console.

  2. In the top navigation bar, select a region.

  3. In the left-side navigation pane, choose Cloud-native Gateway > Alerts > Policies.

  4. In the upper-right corner of the Cloud-native Gateway Alert Policy Management page, click Create Cloud-native Gateway Alerts.

  5. On the Create Cloud-native Gateway Alerts page, configure the parameters and click Save. The following table describes the parameters.



    Alert Rule Name

    Enter a name for the alert rule.


    Select the gateway that you want to manage.

    Alert Contact Group

    Select Gateway Alert Group. This parameter specifies the group of the alert metrics.

    Alert Metric

    Select an alert metric based on your business requirements. Different alert groups support different alert metrics.

    Alert Conditions

    Specify the condition of the alert rule. For example, if the number of requests that the gateway receives per second decreases by 20% compared with the previous day, MSE sends alert notifications.

    Filter Conditions

    Default value: No Filter. The default value indicates that no filter conditions are required.


    Specify the time when the alert event is generated.

    Alert Level

    Select the severity of the alert. The default alert severity is Default. The alert severity increases in the following order: Default, P4, P3, P2, and P1.

    Alert Message

    Enter the alert content that you want to display when an alert is triggered. You can configure alert variables for the Alert Message parameter by using the Go template syntax. Example:

    ID of the instance on which alerting is enabled: {{$label.envoy_clusterid}}
    Alert threshold: {{$labels.metrics_params_value}}
    Actual value for alert triggering: {{ printf "%.2f" $value }}

    The alert information varies based on the alert metrics.

    Advanced Settings

    Click the 展开图标 icon. You can configure the parameters such as Tags and Annotations.

    Alert Check Cycle

    Specify the interval between which alert rule-based checks are performed.

    Alert Notification

    Select Minimalist mode or Normal mode.

    Specify Notification Policy

    If Normal mode is selected for Alert Notification, the alert center of ARMS dispatches and processes alert events and sends alert notifications based on the notification policy that you configured.


    Click Create Tag to create a tag for the alert rule. The tag is used as an option for the dispatching rule.


    Click Create Annotation. Set Key to message and set Value to a value in the format of {{Variable name}}Alert information. The annotation that you created is in the message:{{$labels.pod_name}}Restart}}Alert information format. Example: message:{{$labels.pod_name}}Restart.
