> "Active Threads" on the main gui's status bar has a lower number then "Active Thread Count" when broken down by nodes
>  (i.e. Global Menu -> Cluster)
>  
> This is because "Active Threads" only captures threads by objects that are in the graph (i.e. processors, processor groups, remote processor groups, funnels, input and output ports). [1]
>  
> "Active Thread Count" is more comprehensive and includes these as well as any other threads as well (i.e. reporting tasks, controller services etc.) [2] [3]
>  
> This difference should be documented in the Apache NiFi documentation.
