I see. Grafana and Prometheus tandem is easy to set up using Docker. But 
I agree they are quite heavy components.

Unfortunately, there are no plans to extend the visualization 
capabilities in Stork. Please feel free to open a new ticket in the 
Stork repository to describe your suggestions and address the problem.

The query hit ratio is calculated using the data from the statistics 
endpoint of BIND 9 ('/json/v1'). We retrieve the "QueryHits" and 
"QueryMisses" metrics from the "_default" view of the returned data. The 
ratio is calculated as "QueryHits / (QueryHits + QueryMisses)".

If you see the zero values, it can caused by:

- Communication problem between Stork server and agent
- Communication problem between Stork agent and BIND 9 daemon
- Not configured statistics endpoint in BIND 9
- No DNS traffic in your network

Please, check your BIND 9 configuration and status of the machine and 
application in Stork UI.

Regards,
Slawek
