nagios监控nginx状态
本帖最后由 kjut 于 2014-10-15 08:36 编辑1、服务器与被监控主机安装组件
yum install bc
编译安装nrpe（参考教程：http://www.iyunv.com/thread-26032-1-1.html）
以下为被监控主机设置2、下载监控脚本 check_nginx.sh，并上传到被监控主机的 /usr/local/nagios/libexec目录
下载地址：http://exchange.nagios.org/components/com_mtree/attachment.php?link_id=622&cf_id=24
给予脚本可执行权限
chmod +x /usr/local/nagios/libexec/check_nginx.sh
3、vi /usr/local/nagios/etc/nrpe.cfg添加
command=/usr/local/nagios/libexec/check_nginx.sh -H www.xxx.com -P 80 -p /usr/local/nginx/logs/ -n nginx.pid -s nginx_status -w 15000 -c 20000
其中红色为你要监控的网站；
绿色为nginx.pid的保存路径，可以在nginx.conf中添加：pid /usr/local/nginx/logs/nginx.pid;进行设置，切记。
4、测试脚本运行
cd /usr/local/nagios/libexec
./check_nginx.sh -H www.xxx.com -P 80 -p /usr/local/nginx/logs/ -n nginx.pid -s nginx_status -w 15000 -c 20000
OK - nginx is running. 1 requests per second, 1 connections per second (1.00 requests per connection) | 'reqpsec'=1 'conpsec'=1 'conpreq'=1.00 ]
以下为监控主机设置5、vi /usr/local/nagios/etc/nagios.cfg添加
cfg_file=/usr/local/nagios/etc/objects/nginx.cfg
6、touch /usr/local/nagios/etc/objects/nginx.cfg
vi /usr/local/nagios/etc/objects/nginx.cfg（注意修改被监控端的IP）内容如下
