IPSLA for nexus 9k not producing udp - jitter data

So, we are in a POC for VNQM, and I used the wizard to build the UDP Jitter operation, which worked fine yesterday, then when I opened up the operations today for the device the graphs were gone, with the no data for the time period message. 

The device is definitely producing the IPSLA operation data.

Should I be checking the app server ? Restart services ? We have a pretty big environment with 17 pollers, which are pretty full, but I put these devices on a poller with element room to test.

This is kind of a key time, as if there are issues, there won't likely be buy-in on purchasing a license just for the datacenter side.
