The Agent status can be set to one of the following:
- Healthy: means that the client machine has been communicating, configuration has been requested and basic inventory has been sent lately.
- Needs attention: means that if any of the 'healthy' criterion mentioned above is missing, it is considered that the client machine needs attention.
- Untracked: means that if a computer is not targeted by any "Targeted Agent Settings" policy, then the overall status is counted as 'untracked'.
- Unmanaged: means that the Symantec Management Agent is not installed on that client machine.
