You can quickly assess your agents for any potential critical issues by reviewing logged error messages using the Agents view in the Manager.
Note: The Agent Errors column in the Managed hosts view indicates when an agent associated with a managed host has encountered any errors. However, you can only view an agent's error messages using the Agents view.
To view agent errors
-
In the Navigation view, select Data Governance | Agents.
The Agents view appears.
-
The Critical Error column indicates if there are any error messages logged for an agent.
-
Select the agent from the Agents view, and select View agent errors in the Task view or right-click menu.
Note: The View agent errors task is only available for agents that have error messages logged.
-
The event viewer appears.
Click the 
Clear Events button in the upper left corner to clear the agent errors. Click Yes on the confirmation dialog.
Click the close button in the upper right corner to close the event viewer.
Note: You can also clear error messages for a specific agent using the Clear agent errors task from the Agents view.
You must restart an agent when a new storage volume is added to the managed host being scanned by the agent.
To restart an agent
- In the Navigation view, select Data Governance | Agents.
- Select the required agents in the Agents view, and select Restart agent in the Tasks view or right-click menu.
- Click Yes to confirm.
Note: When a Data Governance agent is restarted, it re-creates all information within its local index. The server index is updated when the full scan completes. An agent will immediately start scanning when the service is restarted if the Immediately scan on agent restart or when managed paths change option is selected. This option is available at the bottom of the Security Scanning page on the Managed Host Settings dialog.
To determine whether data in the client is the most current from the agent, ensure that the data state of the managed host being examined is marked as "Data available."
Note: All agents associated with a managed host are uninstalled when you remove a managed host.
Before removing a managed host ensure that the impact of its removal is considered. Any governed data records or activity information associated with resources on that host is removed from the database as well. Use caution when removing the governance on an item, as there may be business reasons for this setting.
It can take a considerable amount of time to remove a managed host with governed resources (for example, one to two hours per million governed resources). The Manager lists the managed host in the "Deleting" state until this process finishes.
To remove a managed host (and its agents)
- In the Navigation view, select Data Governance | Managed hosts.
-
Select a managed host from the Managed hosts view, and select Remove in the Tasks view or right-click menu.
Note: You can select multiple managed hosts for removal.
The Remove task is not available for host computers with a status of Not Managed.
-
Click Remove to confirm the removal.
If you remove a managed host with governed data, the data is no longer governed. All associated security information and resource activity is also deleted.
All agents associated with a managed host are uninstalled when you remove a managed host. You can, however, remove a remote agent without removing the managed host using the Edit host settings task.
Note: You must have at least one agent assigned to the managed host in order to complete the edit operation.
To remove a remote agent from a managed host
- In the Navigation view, select Data Governance | Managed hosts.
- In the Managed hosts view (right pane), select the required managed host with a status of Managed.
-
Select Edit host settings in the Tasks view or right-click menu.
The Managed Host Settings dialog appears.
-
Open the Agent page, select the agent to be removed and click Remove.
Note: Removing the agent will also remove the managed paths associated with that agent. If that is the desired result, select Yes on the confirmation dialog.
-
Click OK to remove the selected agent.
Note: If you remove the last agent in the list, the OK button will not be available. You will need to specify at least one agent for the managed host before you can save your changes.
