Craft PHP FPM Status Monitor

Craft PHP FPM Status Monitor is a Craft CMS 3 plugin that allows you to monitor PHP FPM status from within the Craft CMS control panel dashboard.

This plugin is a work in progress.

Requirements

• PHP 8.0 (probably works with 7.4 as well)
• PHP running with the FastCGI Process Manager (PHP FPM)
  • Including PHP FPM pm.status_path configured
• Web server configured to allow requests to the configured PHP FPM status path
• This has only been tested on Craft 3.7.35, but probably works on all of 3.x.x
• Composer (I mean, this is a Craft dependency too :))

Installation

1. In terminal, from the root of your Craft project install the package with composer:

composer require noahjahn/craft-php-fpm-status-monitor

or, if you're like me and don't like having dependencies installed on your local machine and would rather install with Docker:

docker run --rm --user $UID:$UID -w /app -v "$(pwd):/app" composer require noahjahn/craft-php-fpm-status-monitor

1. In your browser, logged in to an admin user for your Craft site, open the Control Panel > Settings > Plugins and install the plugin

Configuration

1. Configure the pm.status_path in the PHP FPM configuration on your server

   Example PHP FPM configuration (on your server, or in your container, PHP FPM config probably lives /usr/local/etc/php-fpm.d/):

    pm.status_path = /fpm-status
   

2. Configure the web server to be able to send requests to the status path previously configured

   It's recommended not to allow public access to this endpoint.

   Here is some example nginx configuration under the server block (your fastcgi_pass value will probably be different):

    # Allow fpm ping and status from localhost and private IPs
    location ~ ^/(fpm-status)$ {
        access_log off;
        # Private IPs:
        allow 10.0.0.0/8;
        allow 172.16.0.0/12;
        allow 192.168.0.0/16;
        allow 127.0.0.1;
        deny all;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_pass php-fpm;
    }
   

3. In the control panel of your site, set the path to your chosen path value in the settings of the plugin

Use cases

• View php-fpm status information from the control panel dashboard
