Before a Resource Access Management (RAM) user can use Cloud Monitor to monitor a cloud service, the Alibaba Cloud account to which the RAM user belongs must grant permissions to the RAM user.
Prerequisites
A RAM user is created within your Alibaba Cloud account. For more information, see Create a RAM user.
Procedure
Log on to the RAM console as a RAM administrator.
In the left-side navigation pane, choose .
On the Users page, find the required RAM user, and click Add Permissions in the Actions column.

You can also select multiple RAM users and click Add Permissions in the lower part of the page to grant permissions to the RAM users at a time.
In the Grant Permission panel, grant permissions to the RAM user.
