Include the agent on an image
The agent can be installed on an image that is subsequently deployed to multiple systems. You must
take precautions to make sure the agent functions properly in this scenario.
Tasks
• Correct duplicate agent GUIDs on page 41
Agents with duplicate GUIDs can be automatically identified and removed with a server
task.
Identify duplicate agent GUIDs
No two agents can share the same GUID. The most common way agents can end up with duplicate
GUIDs is if the agent was installed on an image without having its GUID removed, and that image was
deployed onto more than one system.
When these systems attempt to communicate with an Agent Handler, they generate sequencing
errors, which indicate a GUID problem. The Managed Systems query result type tracks the following
information about these errors:
• The number of sequence errors for each system in the Managed Systems Sequence Errors property.
• The date and time of the last sequence error in the Managed Systems Last Sequence Error property.
The tracked information is incorporated into one of the available predefined queries:
•
Systems with High Sequence Errors
•
Systems with no Recent Sequence Errors
Two predefined tasks help manage GUID problems.
•
Duplicate Agent GUID ‑ remove systems with potentially duplicated GUIDs
This task deletes the systems that have a large number of sequencing errors and classifies the
agent GUID as problematic. As a result, the agent is forced to generate a new GUID. The threshold
number of sequencing errors is set in the query Systems with High Sequence Errors.
•
Duplicate Agent GUID ‑ Clear error count
Sequencing errors can occur occasionally for inconsequential reasons. This task clears the count of
sequencing errors in systems that have not had any recent sequencing errors. This cleanup task
does not remove any problematic GUIDs. The threshold value for defining recent is set in the query
Systems with no Recent Sequence Errors
Correct duplicate agent GUIDs
Agents with duplicate GUIDs can be automatically identified and removed with a server task.
You can schedule this task to run periodically, or run it immediately.
Task
For option definitions, click ? in the interface.

Click Menu | Automation | Server Tasks, then edit the Duplicate Agent GUID ‑ remove systems with potentially
duplicated GUIDs task.
To run this task immediately, click Run. The Server Task Log page appears after running the task.
