if you import the grafana dashboard, you must set blocky's REST url. This should be the ip of your raspberry and port 4000. Something like: http://raspberry_ip:4000
Can you check it please?

You're right! Thanks a lot.
I found there is "Http://localhost:4000" on the dashboard's value.
It works properly after change to "http://raspberry_ip:4000".

Now it's time to move on next task - Query Log
