We need to gather metrics from php-fpm, much alike what we do for HHVM and any other application server we run in production.
The best such tool for prometheus seems to be php-fpm-exporter. We need to package it, install it, and start gathering metrics.
Creation of dashboards can be postponed to when we'll have a better idea of what's available, and significant, in terms of metrics.
