PHP FPM custom ZABBIX monitoring

Customize php-fpm zabbix Monitoring template
According to the above experiment
In the device 1、 equipment 2 On the basis of
equipment 1 192.168.70.10 zabbix-server
equipment 2 192.168.70.20 zabbix-agent

equipment 2：
install php-rpm service

[[email protected]]# yum -y install php-fpm

modify php-fpm The configuration file opens the status page function （ Search for ：status）

[[email protected]]# vim /etc/php-fpm.d/www.conf
pm.status_path = /php_status  # Uncomment and rename php_status

start-up php-fpm

[[email protected]]# systemctl start php-fpm 

Set power on self start

[[email protected]]#systemctl enable php-fpm

modify nginx The configuration file specifies php To configure （Ctrl+v Decline in Visual block appears uncomment ）

[[email protected]]#vim /etc/nginx/conf.d/default.conf
……
location /php_status {      # Appoint php page   name  
       root                 html;
       fastcgi_pass   127.0.0.1:9000;
       fastcgi_index     index.php;
       fastcgi_param    SCRIPT_FILENAME   /scripts$fastcgi_script_name; # Configuration environment 
       include fastcgi_params;
  }

restart nginx

[[email protected]]#systemctl restart nginx

Test access php Status page ：http://192.168.70.20/php_status

php-fpm status Detailed explanation of status value  
pool：fpm Pool name , Most of them are www 
process manager： Process management , value ：static,dynamic or ondemand 
start time： Start date , If reload 了 php-fpm, Time will be more   new 
start since： Run time  
accepted conn： The number of requests currently accepted by the pool 
listen queue： Request waiting queue , If the value is not 0, Then increase   Add FPM The number of processes 
max listen queue： The highest number of request waiting queues  
listen queue len：socket Waiting queue length 
idle processes： Number of idle processes  
active processes： Number of active processes  
total processes： Total number of processes  
max active processes： Maximum number of active processes （FPM Start on   Initial calculation ） max children reached： The number of times the maximum number of processes is limited , If this   The number of pieces is not 0, That means your maximum number of processes is too small , It needs to be set larger  
slow requests  When enabled php-fpm slow-log When the function , Such as   Fruit appears php-fpm The slow request counter will increase , Generally inappropriate Mysql check   Inquiry will trigger this value
