Example: Pull MySQL Performance summary

pt-mysql-summary conveniently summarizes the status and configuration of a MySQL database server so that you can learn about it at a glance.

pt-mysql-summary --host localhost --user root --ask-pass

When prompted for the MySQL root user password, provide it to get stats.

You can as well redirect the output to a file.

pt-mysql-summary --host localhost --user root --ask-pass > mysql-summary.txt

See sample output below:
