前段时间在公司IDC服务器上部署了zabbix3.0.3监控系统，除了自带的内存/带宽/CPU负载等系统资源监控模板以及mysql监控模板外，接下来对诸如nginx、php、memcache、磁盘IO的监控项配置在此做下记录，希望能帮助到有用到的朋友们~

nginx的监控模板：zbx_nginx_templates.xml
php的监控模板：zbx_php-fpm_templates.xml
memcache的监控模板：zbx_memcached_templates.xml
Low-level discovery监控磁盘IO的监控模板：Template Linux DiskIO.xml

以上四个监控项的模板的下载地址：http://pan.baidu.com/s/1geAMZfl （提取密码：zpyx）

--------------------------------------------------------------------------------------------------
一、配置nginx的监控
1）首先在客户机的nginx配置文件里添加：
[root@115r ~]# vim www.world.huanqiu.conf
.......
location /nginx_status {
stub_status on;
access_log off;
}
........

添加后，重启nginx服务:
[root@115r ~]#/usr/local/nginx/sbin/nginx -s reload

2)zabbix监控nginx的自定义键值

在客户机的zabbix的monitor_scripts目录下添加nginx-status.sh文件，进行如下配置（这个配置可以适用于其他机器的nginx监控）
[root@115r ~]# cd /usr/local/zabbix/monitor_scripts/
[root@115r monitor_scripts]#cat nginx-status.sh
#!/bin/bash
