Installing UniAgent on an ECS

Scenarios

Self-service O&M operations on ECSs such as hostname change and online password reset depend on UniAgent provided by Application Operations Management (AOM).

If UniAgent is not installed or the installation failed, you need to log in to the ECS and install UniAgent before performing self-service O&M.

You can install UniAgent in either of the following ways:

• Installing UniAgent on the ECS Console: When you intend to perform self-service O&M operations on an individual ECS and a message is displayed indicating that UniAgent is not installed or the installation failed, install UniAgent on the ECS console.
• Installing UniAgent on the Collection Management Console: When you intend to perform self-service O&M operations on multiple ECSs and a message is displayed indicating that UniAgent is not installed or the installation failed, install UniAgent on the Collection Management console.
