VE performance tab is not updated after VE migration from one hardware node to another, in case the target node was the owner of this VE in the past already.
The following errors appear in
/var/log/pa/vps.snmp.log on OACI IM server:

No service restart helps to bring resource usage statistics back.
Other VEs on the same nodes are not affected.
In case the target node already contained records of the VE in the past, the statistics fail to get updated. The issue is acknowledged as CCU-14758.
Contact Odin Technical Support to apply a workaround for the problem.
