How to check if php-fpm is installed and running correctly?

Question

As in title, how to check php-fpm status? Is it running? How many request serving? Thanks.

Answer 1

Is ps -ef | grep php-fpm too simple an answer for the first part?

You could also use the ping feature that you can enable with the ping.path configuration directive.

The second part can be achieved with the pm.status_path configuration directive that gives you access to a number of statistics, including the number of accepted connections.
