Creation Mode

You can create multi-resource threshold rules as required.

For multi-resource threshold rules (taking effect in CN North-Beijing1 and CN East-Shanghai2 only), resources and rules are in many-to-one relationship. When multiple resources are monitored, only one rule is generated after the creation is complete. Multiple resources are monitored by the same rule.

To monitor multiple resources in a centralized manner, you need to create a static threshold template. For details, see Using a Static Threshold Template to Create a Multi-Resource Threshold Rule. Static threshold templates are used for creating multi-resource threshold rules. For how to create a static threshold template, see Creating Static Threshold Templates.

Precautions

• You can create a maximum of 1000 threshold rules. If the maximum number has been reached, delete unnecessary rules and create new ones.
• Setting a notification policy
  To send email or SMS notifications if the threshold rule status (Exceeded or OK) changes, set a notification policy on the SMN console according to the following procedure. If you do not need to receive notifications, skip the following procedure. The procedure is as follows:

  1. Create a topic according to Creating a Topic.
  2. Set a topic policy according to Configuring Topic Policies.

     Select apm for Services that can publish messages to this topic. Otherwise, notifications cannot be sent.

  3. Add a subscriber, that is, the email or SMS notification recipient, for the topic according to Adding a Subscription.

Using a Static Threshold Template to Create a Multi-Resource Threshold Rule

This function takes effect only in CN North-Beijing1 and CN East-Shanghai2.

Before creating a multi-resource threshold rule, create a static threshold template according to Creating Static Threshold Templates.

1. Log in to the APM console. In the navigation pane, choose Alarm Center > Threshold Rules.
2. Click Adding a multi-resource threshold in the upper right corner of the page.
3. Set parameters based on Table 1.

   Parameter	Description	Example
   Threshold name	Enter a threshold name.	apm
   Description	Enter a description.	-
   Apply to All Applications	: One threshold rule will be created for all applications and services. : You can select one or more resources to monitor. To monitor all services under an application, select them by application.	-

4. Enter an application or instance name in the search box to search, select resources, and click Next.
5. Select the created static threshold template and metric.
   • If no template is available, click Create Static Threshold Template. For details, see Creating Static Threshold Templates.
