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
.

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
, socket
or address
. 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
- name: remote
address: 203.0.113.10:9000
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
