Example 3: Enabling an AS Group

Scenarios

This section describes how to enable an AS group by calling APIs. For details, see Calling APIs.

An AS group consists of a collection of instances that apply to the same scenario. It is the basis for enabling or disabling AS policies and performing scaling actions.

Only enabled AS groups support scaling actions.

Involved APIs

• Obtaining a User Token: Determine the user token that can be used to authenticate the calling of other APIs.
• Querying AS Groups: Determine the AS group to be enabled.
• Enabling or Disabling an AS Group: Enable the AS group you specify.

Procedure

1. Determine the user token that can be used to authenticate the calling of other APIs.
   1. View the user token. For details, see Obtaining a User Token.
   2. Obtain the value of X-Subject-Token in the response header.

2. Determine the AS group.
   1. View AS groups.
