I have installed the PI-Hole app on Splunk enterprise 7.2.3  
Pi_Hole 4.1.1  (FTL 4.1.2) is running on an other Ubuntu Linux system with the Splunk Universal forwarder installed. 
 In the Splunk PI-Hole App is only see the below graphs on the home screen filled with data:  
Blocked Requests by SRC  
Top 10 Requested Domains  
Top 10 Blocked Domains  
Top Record Types 
 The other field are zero or say "No result found". 
 The "More PI-Hole" screen looks complete. 
 Do I need some extra configuration or are some searches not OK?
