Smart Agent allows you to manage the agent operations (install, upgrade, and rollback) for the supported agents by using the Controller user interface. It also provides Smart Agent CLI option for advanced configurations.
You can use the Controller UI to view all the installed agents with the inventory details. The Smart Agent inventory is also displayed along with other agent inventory details.
You must install Smart Agent on each host where you want to use the Controller UI to perform the agent management.
