We have many critical systems that getting an agent on is a horrendous task and anytime anything goes wrong it will be the agents fault. So I would LOVE to see an agentless pull. This could be similar to how SAM looks at logs. It can have credentials that log into the system, regardless of OS, and will go to the file you configure and grab the logs.
Since the technology is already there for SAM, I would think this would be doable.
