nagios监控nginx状态（check_nginx_status.pl）
1、安装所需组件yum install perl perl-devel perl-CPAN bc -y
perl -MCPAN -eshell& cpan> install Bundle::LWP
编译安装nrp
以下是被监控端设置2、下载check_nginx_status.pl脚本
下载地址：https://codeload.github.com/regilero/check_nginx_status/zip/master
解压文件后，上传check_nginx_status.pl到/usr/local/nagios/libexec
chmod +x check_nginx_status.pl
chown nagios.nagcmd check_nginx_status.pl
3、在被监控端测试脚本
cd /usr/local/nagios/libexec
./check_nginx_status.pl -H 192.168.1.247 -s www.xxx.com -P 80
NGINX OK -0.067 sec. response time, Active: 1 (Writing: 1 Reading: 0 Waiting: 0) ReqPerSec: 0.111 ConnPerSec: 0.111 ReqPerConn: 1.000|Writing=1;;;; Reading=0;;;; Waiting=0;;;; Active=1;;;; ReqPerSec=0.111111;;;; ConnPerSec=0.111111;;;; ReqPerConn=1.000000;;;;
其中红色为nginx服务器的IP地址；绿色为需要监控的网站网址。
4、vi /usr/local/nagios/etc/nrpe.cfg添加
command=/usr/local/nagios/libexec/check_nginx_status.pl -H 192.168.1.247 -s www.xxx.com -P 80
5、删除/tmp生成的192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9不然后面后报错！提示无法生成文件。
rm /tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9
以下是nagios主机的设置
5、服务器端测试 /usr/local/nagios/libexec/check_nrpe -H 192.168.1.247 -c check_nginxNGINX OK -0.065 sec. response time, Active: 1 (Writing: 1 Reading: 0 Waiting: 0) ReqPerSec: 0.020 ConnPerSec: 0.020 ReqPerConn: 1.000|Writing=1;;;; Reading=0;;;; Waiting=0;;;; Active=1;;;; ReqPerSec=0.020000;;;; ConnPerSec=0.020000;;;; ReqPerConn=1.000000;;;;
vi /usr/local/nagios/etc/nagios.cfg添加
cfg_file=/usr/local/nagios/etc/objects/nginx.cfg6、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****************************************我是分割线************************************
