I have been making some visualizations on kibana, it runs smooth at first; however, when time goes on, some graphs displayed something not in sense. It displays the message that
"No results displayed because all values equal 0".
The problem is it did receives input but can only show results for not raw field.
Figure 1: With raw field for hostname
Figure 2: Without raw field for hostname, however, my machine hostname is called Win-07llqen2sjb, but not 2 machines.
