how to confirm if application metering agent is sending inventory data to NS or not

Hi,

We have NS 7.1 SP2.

I noticed that our executable usage report for one of our licensed applications is not correct. There seems to be no inventory being sent to the NS for the last 3 months. how could I check with the application metering agent if it is sending inventory data (or not) on a regular basis?

thank you in advance,
