PHP-FPM status page
To enable the PHP-FPM status page add the following code to your PHP-FPM pool configuration file.

pm.status_path = /status_phpfpm
Now make the following changes to your NGiNX configuration file.

server {
server_name localhost;
location /status_phpfpm {
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
deny all;

You can test if the status page is working by running
wget -qO-

Configure the plugin
To enable the plugin edit the nixstats configuration file. This file is usually located at /etc/nixstats.ini.

Add the following settings to the end of the file.
enabled = yes
status_page_url =

Test to see if the plugin is working by running nixstatsagent --test phpfpm. It should show the following metrics:

"accepted_conn": 3015,
"accepted_conn_per_second": 0.0,
"active_processes": 1,
"idle_processes": 0,
"listen_queue": 0,
"listen_queue_len": 128,
"max_active_processes": 1,
"max_children_reached": 0,
"max_listen_queue": 1,
"pool": "www",
"process_manager": "ondemand",
"slow_requests": 0,
"start_since": 294686,
"start_time": 1492504250,
"total_processes": 1

Now you can restart the agent service nixstatsagent restart to start monitoring PHP-FPM.
