zabbix监控apache_status状态的例子

1.在client的httpd.conf中添加如下

sudo vim /alidata/server/httpd/conf/httpd.conf

    SetHandler server-status
    Allow from 127.0.0.1
    Order deny,allow
    Deny from all

ExtendedStatus On
如果你有rewrite规则，则需要在.htaccess中加上一条，如下：

RewriteCond %{REQUEST_URI} !server-status需要写在index.php之前
sudo vim /alidata/www/jds.jince.com/.htaccess
# ThinkPHP Rewrite规则

   RewriteEngine on
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_URI} !server-status
   RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]

#禁止显示目录列表
Options -Indexes
2，重加载apache配置
Check uptime并重启apache

sudo /etc/init.d/httpd configtest 无错误后
sudo /etc/init.d/httpd graceful
可以使用curl 127.0.0.1/server-status测试
3，在zabbix-agent上创建目录和脚本

sudo mkdir /etc/zabbix/scripts
sudo vim /etc/zabbix/scripts/check_apache.sh
将check_apache.sh放入client的/etc/zabbix/scripts

# end zapache
给脚本执行权限

sudo chmod +x /etc/zabbix/scripts/check_apache.sh
4.将userparameter_apache.conf放入client的/etc/zabbix/zabbix_agentd.d，内容如下：

sudo vim /etc/zabbix/zabbix_agentd.d/userparameter_apache.conf
UserParameter=zapache[*],/bin/bash /etc/zabbix/scripts/check_apache.sh $1
5.重启agentd

/etc/init.d/zabbix-agent restart
$ sudo /etc/init.d/zabbix-agent restart
测试

sudo sh /etc/zabbix/scripts/check_apache.sh CPULoad
2.06619
修改权限

sudo  chown zabbix.zabbix /tmp/zapache-http___localhost_server-status_auto.*
文件如下：

-rw-r--r-- 1 zabbix zabbix       440 Mar 17 14:29 zapache-http___localhost_server-status_auto.cache
-rw-r--r-- 1 zabbix zabbix         0 Mar 17 14:29 zapache-http___localhost_server-status_auto.ts
6.在zabbix server 中创建Template App Apache service模板，添加items, 关联需要监控的apache主机即可

apache服务监控可参考如下：
