Every day around the same time the server becomes unresponsive for a couple of minutes. Sometimes for longer. I have looked at http during and its a huge amount of php-fpm requests running using 100% of CPU at the time. The server runs a lot of sites and I want to narrow down which site is causing the issue. Web Statistics dont really tell me which site is doing this. Is there an easy way to change http to show requested file for each php-fpm thread? Or something similar that will help diagnose this? Thanks.
