Creating an Alarm Rule

Cloud Eye allows you to use alarm templates to create alarm rules, making it easy and convenient to add or modify alarm rules for resources or cloud services, especially for a large number of resources and cloud services.

You can use a default alarm template to create an alarm rule for a cloud service resource.

You can create alarm rules for CBR.

Procedure

  1. Log in to the management console.
  2. Under Management & Deployment, select Cloud Eye. In the navigation pane on the left, choose Alarm Management > Alarm Rules.
  3. On the displayed page, click Create Alarm Rule in the upper right corner.
  4. On the displayed Create Alarm Rule page, configure the parameters.
    1. Set Name and Description.
