Managing OS with credentials ( or otherwise) other than root?

Being relatively new to OpsCenter, I thought I would poll the community on how to address the security issue posed by having OpsCenter agents su to root (or equivalent user) . I was hoping that by using the agent, I would possibly avoid the su being logged and flagged for audit purposes.

Can anyone tell me how they are addressing this? Is there a better way to manage them. than SSH, that I'm not seeing. Documentation indicates that root level privileges are required to manage the OS's. Any info that any of you can provide, is appreciated, in advance.
