OpsCenter collect data issue for Capacity Licensing report

[Edwork]

I run Capacity Licensing report and get the following result. I use NBU7.1 and Opscenter 7.1. Not agent installated as Admin doc said. But...

How should I fix it ?

-------------------------------------------

OpsCenter was unable to generate your Capacity Licensing report.

Data collection failed on all selected master servers. See details below for more information.

WARNING
OpsCenter was unable to collect information from one or more master servers.Partially complete data collection will affect the accuracy of the final report.


Master Server            Status                   Last Exception           
master.domain.com        Failed                   Opscenter Agent is not connected

Check the following conditions to correct the problems.
1.Verify that data collection has been enabled for the master servers. [Go to Setting -> Configuration -> NetBackup -> Select specific master server -> Edit].
2.Verify the services are running on the master servers.

But Under Web portal data collection status shows all info. could be retrieved except subjobs.

You need an agent if you want report on Capacity LIcensing .There is no need for agent to collec tdata from Netbackup 7.x Master srever but Licensing is a special category .This will be continue in Opscenter7.5 where Traditional Licensing report is also introduced.
