•

To apply the new features, update the agents to the latest version. You can upgrade the agents one by one, by selecting from the table and clicking the corresponding Update Agent link in the Agent version column. You can upgrade all agents at once by selecting all the listed agents and clicking the Update Agent button at the top of the list.
To perform an agent management command, select one or more check boxes in the left-most column and click the appropriate button. For example, to start an agent’s data collection, select the check box in the agent row and click Start Data Collection.
