SYMPTOMS
OVO Node is not managed or missing.

These errors are telling you that the GUID the connector is trying to update in OVO does not exist.



CAUSE
This can happen when either the node is not part of a 'Node Group' in OVO or there is a 'Template' catching the initial event from the node in question and discarding it.



RESOLUTION
You can find out what node is causing this error by putting the connector in debug mode '1 - ALL' and looking for the 'Invalid ID' returned in the momprodconn.log. Above the error will list all the properties the connector is passing to OVO and the node name/ip will be one of them.

Once you determine what node is causing the issue try running the 'opcmsg' command from a command prompt on the OVO server and generate an event for the node in question and see if it displays in the OVO Message Browser. If it displays properly then you most likely have a template catching the alert coming from MOM and discarding it.

If it does not display the event in the OVO Message Browser verify the node is part of a 'Node Group' or check your templates.



MORE INFORMATION
The connector works as follows:
 * 1) New alert is generated in MOM.
 * 2) Auto-forward rule in MOM sends alert to OVO.
 * 3) OVO agent on OVO server accepts new alert from MOM and returns the GUID for the event in OVO to MOM and stores it in the 'Ticket ID' field of the MOM alert.
 * 4) OVO agent forwards event up to OVO server.
 * 5) OVO server checks the event against 'Node Groups' and 'Templates' to verify event should be accepted or rejected.
 * 6) If the event is rejected, the next time the connector tries to modify/acknowledge the event from MOM, OVO will return the error 'Invalid ID' as it was not added to the OVO database.
