After upgrading OpsCenter to 8.3/8.3.0.1, some virtual machines have a date-time stamp appended to their name

Problem

After upgrade of Opscenter to 8.3 / 8.3.0.1 unexpected client names are found in reports.

Using Monitor > Hosts > Clients

Note that names of VMware clients are seen with an additional name for each, with the original name appended by a date.

e.g.

Clientname1
Clientname1(07-12-20 06:09)
Clientname2
Clientname2(07-12-20 06:09)

Error

There is no error message.

Cause

As part of the dynamic views feature in 8.3, there were changes made to the Virtual Machine data collector.  
Prior to 8.3, attributes re-used between virtual machines have a tendency to cause OpsCenter to mark both virtual machines as the same host.  This makes monitoring and reporting inaccurate.  

Starting with 8.3, OpsCenter can now distinguish different virtual machines based on a combination of attributes. This way, new and cloned virtual machines are distinguished as different hosts from previous hosts.  Thus, in Monitoring and Reporting there will be segregation of each virtual machine as a unique host.

When the display name is the same as an existing host, a date-time stamp is appended to the name to distinguish it from the existing virtual machine.
That is the reason why some clients show up with a date-time stamp appended to the name.

For example, this matter is caused in OpsCenter 8.3 and some other versions when virtual machine is moved to different ESXi server.

Note:  Custom reports that have client name from the domain_Client table in the filter list may need to have "like" in the query so it does not try to do an exact match.

Example:  
Old query:  name = 'test_vm1'
New query: name like 'test_vm1%'

Solution

By apply the EEB, remove the date/time stamp name appendages.  If you are interested in this, please contact Veritas Technical Support and reference the following tracking numbers:
