zabbix通过自定义脚本监控nginx，php-fpm和mysql占用内存数和进程的个数

首先，在zabbix脚本目录下添加一个脚本，写入如下代码

#!/bin/bash

#license:GPL

#mail:admin@huxianglin.cn

#date:2015.04.16

top -bn1>/usr/local/zabbix-2.4.4/scripts/process.log

LOG=/usr/local/zabbix-2.4.4/scripts/process.log

php_fpm(){

grep "php-fpm" $LOG |awk '{sum+=$6}; END{print sum}'

}

php_fpm_num(){

grep "php-fpm" $LOG |wc -l

}

nginx(){

grep "nginx" $LOG |awk '{sum+=$6}; END{print sum}'

}

nginx_num(){

grep "nginx" $LOG |wc -l

}

mysqld(){

grep "mysqld" $LOG |awk '{sum+=$6}; END{print sum}'

}

mysqld_num(){

grep "mysqld" $LOG |wc -l

}

case "$1" in

php_fpm)

php_fpm

;;

php_fpm_num)

php_fpm_num

;;

nginx)

nginx

;;

nginx_num)

nginx_num

;;

mysqld)

mysqld

;;

mysqld_num)

mysqld_num

;;

*)

echo "Usage: $0 {php_fpm|php_fpm_num|nginx|nginx_num|mysqld|mysqld_num}"

esac

保存之后修改其属组和属主为zabbix.zabbix,然后新建一个文件process.log，同样设置属主和属组为zabbix.zabbix

然后编辑zabbix_agentd.conf文件，在最后添加上下面这段代码，并重启zabbix_agentd服务

UserParameter=process.php_fpm,/usr/local/zabbix-2.4.4/scripts/processstatus.sh php_fpm

UserParameter=process.php_fpm_num,/usr/local/zabbix-2.4.4/scripts/processstatus.sh php_fpm_num

UserParameter=process.nginx,/usr/local/zabbix-2.4.4/scripts/processstatus.sh nginx

UserParameter=process.nginx_num,/usr/local/zabbix-2.4.4/scripts/processstatus.sh nginx_num

UserParameter=process.mysqld,/usr/local/zabbix-2.4.4/scripts/processstatus.sh mysqld

UserParameter=process.mysqld_num,/usr/local/zabbix-2.4.4/scripts/processstatus.sh mysqld_num

之后就可以在web页面添加item，生成图表了，注意top取到的内存单位是KB，所以在定义item的时候需要自定义单位和设定倍数

生成的各个程序占用内存大小的图形如下

生成的各个程序的进程个数图形如下，可以设定触发器，当进程满足触发其条件时发送报警
