Zabbix 4.0 Template for PHP-FPM Pools

This is a template for monitoring php-fpm and it's pools with Zabbix.

What's special about this template, is that it automatically detects (using LLD) the running php-fpm pools and creates items for measuring metrics from each pool. It uses Http Agent type check in zabbix in order to parse the php status information into useful metrics.

So, if you are running a server with multiple php-fpm pools, this may be a better alternative for monitoring php than other templates available.

Compatibility

This template was tested using:

Software	Vesion
Zabbix Server	4.0.3
Debian	Stretch (9.8)
Php-fpm	7.2

It might also work with other combination of versions.

Metrics

This are the metrics created for each php-fpm pool:

Requirements

• Php-status should be enabled in the php-fpm pools.
• Php-status should be accessible and located in /php-status_POOLNAME for each pool (see step 4 of Setup).

Setup

Even though this template is made with automation in mind, there's still some manual steps to be done in the client (where php-fpm and zabbix-agent are running) in order to get it working:

1. Clone this template into a temporary directory.

   # git clone https://github.com/vigrai/zabbix-template-php-fpm.git /tmp/zabbix-template
   

2. Put the file php-fpm.discover_pools.pl into the /etc/zabbix directory and make it executable.

   # cp /tmp/zabbix-template/php-fpm.discover_pools.pl /etc/zabbix
   # chmod +x /etc/zabbix/php-fpm.discover_pools.pl
   # chown zabbix.zabbix /etc/zabbix/php-fpm.discover_pools.pl
   

3. Copy the file userparameter_php-fpm.conf into /etc/zabbix/zabbix_agentd.d.

   # cp /tmp/zabbix-template/userparameter_php-fpm.conf /etc/zabbix/zabbix_agentd.d
   

4. Make sure that your php-fpm is correctly setup:

   [x] The pools should have php-status enabled.

   [x] Php-status should be available in the path /fpm-status_[NAME-OF-THE-POOL]

   Example configuration file for pool called nms (/etc/php/7.2/fpm/pool.d/nms.conf):

   [nms]

   pm.status_path = /fpm-status_nms

   [x] Php-status should be accessible for each pool. This is an example configuration file for nginx:

   ## Example configuration file for serving php-status of each php pool using nginx.
   # Take-aways:
   #  1.- The location should be in the format /fpm-status_POOLNAME
   #  2.- The proxy_pass should point to the correct pool. In this case unix sockets are used, but it'd be similar with a network connection (example: fastcgi_pass 127.0.0.1:9001).
   
   server {
      listen 0.0.0.0:8080;
      server_name status.localhost;
   
      keepalive_timeout 0;
   
      # Allow the ip of the Zabbix Proxy/Server which is going to perform the polling.
      # In this case, I am installing on the same host, so 127.0.0.1.
      allow 127.0.0.1;
      deny all;
   
      location /fpm-status_nms {
              include fastcgi_params;
              fastcgi_pass unix:/var/run/php/php7.2-nms-fpm.sock;
              fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
      }
   
      location /fpm-status_website1 {
              include fastcgi_params;
              fastcgi_pass unix:/var/run/php/php7.2-website1-fpm.sock;
              fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
      }
   
      location /fpm-status_website2 {
              include fastcgi_params;
              fastcgi_pass unix:/var/run/php/php7.2-website2-fpm.sock;
              fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
      }
   
      location /fpm-status_website3 {
              include fastcgi_params;
              fastcgi_pass unix:/var/run/php/php7.2-website3-fpm.sock;
              fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
      }
   
      access_log off;
   
   }
   

5. Check that the script is finding the running pools:

   # /etc/zabbix/php-fpm.discover_pools.pl
   {
       "data":[
   
       {
               "{#POOLNAME}":"nms"
       }
       ,
       {
               "{#POOLNAME}":"website1"
       }
       ,
       {
               "{#POOLNAME}":"website2"
       }
       ,
       {
               "{#POOLNAME}":"website3"
       }
   
       ]
   
   }
   

6. If the script is returning the pools, you are ready to go. Import the zabbix-template-php-fpm.xml file in your Zabbix GUI and make sure that the macros are correctly setup, this are the values by default:
