Convert null value into zero value #166

Open FMMTG opened 5 years ago

FMMTG commented 5 years ago

What happened:

Hello, We have monitored a entire network of fiber optic, and in a query We make mathematical calculations, the problem is when in a part of mathematical calculations the value is null or We havenot value, in this moment the Grafana doesnot show nothing (only no data points).

It is possible convert the null value into zero value? We have tried the option of Stacking & Null value but the problem persist.

Hi @FMMTG, if I understand your problem correctly you have issue with grafana and prometheus. As this project is only about generating dashboard definitions to grafana there is not much how I can help BUT I will check whether generator works correctly and does properly generate null and stacking properties.
