This is exception generated during tsdr automation execution.

Automation steps are,
1.Start the mininet topology
2.Waiting for tsdr metrics collection (basically it will poll data from mdsal-stats)
3.Stop the mininet topology
This above 3 step executed continous 5 times without stopping the controller.

Whenever stop and start mininet topology,this NPE started to thrown.

Comment by Jozef Gloncak [ 11/Jun/15 ]

Can you also specify what are tsdr metrics?

Just to be sure.

Are you using feature odl-openflowplugin-flow-services-ui?

I started odl-openflowplugin-flow-services-ui.
Then I started mininet with cpqd.
I let it run (without no interaction, no data puting, posting) for a while (approximately 1 minute).
After shutdown I couldn't see error reported by you - >>processing (translate, publish) of ticket failed<<

Hari - can you look at this when you get free? Can be after M5 if you are pressed for time.

Hi,

Closing because of no activity for the long time. Please reopen if it still valid and needed.

Thanks,
Miro
