How to Configure MySQL for Percona Monitoring and Management

I can not get any analytics from _PMM Query Analytics showing


https://www.percona.com/doc/percona-monitoring-and-management/conf-mysql.html this is that link.
I changed the configuration as mentioned in this page, but after that pmm is not monitoring automatically!
What should I do after changing those configurations.
Does anyone know how to configure PMM-Client properly to get Query Analytics?
I’m using percona v5.7
