PHP-FPM monitoring with Netdata

PHP-FPM is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites.

This module will monitor one or more php-fpm instances, depending on your configuration.

Requirements

• php-fpm with enabled status page:
  • open the php-fpm configuration file.
  • inside this file, find and uncomment the variable pm.status_path = /status.
• access to status page via web server.

Charts

It produces following charts:

• Active Connections in connections
• Requests in requests/s
• Performance in status
• Requests Duration Among All Idle Processes in milliseconds
• Last Request CPU Usage Among All Idle Processes in percentage
• Last Request Memory Usage Among All Idle Processes in KB

Configuration

Edit the go.d/phpfpm.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory

sudo ./edit-config go.d/phpfpm.conf

Needs only url or socket. Here is an example for local and remote servers:

jobs:

- name: local

url: http://localhost/status?full&json

- name: local

url: http://[::1]/status?full&json

- name: local_socket

socket: '/tmp/php-fpm.sock'

- name: remote

url: http://203.0.113.10/status?full&json

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the phpfpm collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

First, navigate to your plugins directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/

sudo -u netdata -s

You can now run the go.d.plugin to debug the collector:

./go.d.plugin -d -m phpfpm
