NPC has the time frames 'Last 4 hours' and 'Last 8 hours' which NetVoyant does not have.

 

In older versions of NPC when a time frames is selected which does not exist in NV it returns no data, in later versions it was 'fixed'.

When 'Last 4 hours' is selected, because NetVoyant is processing data in hourly rollups it does not have a 4 hour data point. As a result it returns the data only for the first hour of that 4 hour time frame. If it so happens that there was no data for that first hour then it will return nothing and NPC will show No NetVoyant data. If the time frame is changed to 'Last 24 hours' which corresponds to the NetVoyant 'Last day' time frame then it will show all data collected for the last 24 hours including the 4 hour time frame previously reported to have no data. The same thing happens for other NPC time frames that do not correspond to NetVoyant time frames.

topn_patch.zip was released for NPC 6.1.194 which changes the functionality for these views so that NetVoyant data will be presented for the full time frame as expected.
