Absolutely nothing shows in any [Filebeat] Kibana Dashboards (“No results found”)

On Windows 10, I enabled Kibana and System in filebeat. I'm not sure if System would work, but Kibana should.

According to the kibana.yml for filebeat (also the same in system.yml):

# Set custom paths for the log files. If left empty,
# Filebeat will choose the paths depending on your OS.
#var.paths:

I would like to know what log path is actually set in filebeat.
I could not find any info in > .\filebeat.exe setup -e !
And Logstash isn't installed, it doesn't work well with filebeat!?

Strangely, filebeat retrieves the elasticsearch log even I didn't enable the module. So, there's finally sth to see. However, even I could start filebeat with the specific Kibana log, I couldn't use it in the kibana.yml, it just won't take what I used in command line option...

Finally figure out the correct config syntax for the filebeat kibana modules. Unfortunately filebeat log doesn't say anything about module config, have to use the setup option to test it.

Now I can find get log and tags in Discover, but I could not get those in editing(new) Dashboard.
