nagios監控nginx狀態（check_nginx_status.pl）

標籤：nagios   check_nginx   監控nginx   

1、安裝所需組件

   yum install perl perl-devel perl-CPAN bc -y

   perl -MCPAN -eshell  & cpan> install Bundle::LWP

   編譯安裝nrpe（參考教程：http://2860664.blog.51cto.com/2850664/1559056）

以下是被監控端設定

2、下載check_nginx_status.pl指令碼

   ：https://codeload.github.com/regilero/check_nginx_status/zip/master

   解壓檔案後，上傳check_nginx_status.pl到/usr/local/nagios/libexec

   chmod +x check_nginx_status.pl

   chown nagios.nagcmd check_nginx_status.pl

3、在被監控端測試指令碼

   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;;;;

   其中紅色為nginx伺服器的IP地址；綠色為需要監控的網站網址。

4、vi /usr/local/nagios/etc/nrpe.cfg  添加

command[check_nginx]=/usr/local/nagios/libexec/check_nginx_status.pl -H 192.168.1.247 -s www.xxx.com -P 80

5、刪除/tmp產生的192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9不然後面後報錯！提示無法組建檔案。

   rm /tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9

   

以下是nagios主機的設定

5、伺服器端測試

   /usr/local/nagios/libexec/check_nrpe -H 192.168.1.247 -c check_nginx

NGINX 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.cfg

6、touch /usr/local/nagios/etc/objects/nginx.cfg

   vi /usr/local/nagios/etc/objects/nginx.cfg  （注意修改被監控端的IP）內容如下

報錯資訊

7、nagios伺服器報錯

NGINX UNKNOWN - unable to write temporary data in:/tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9

解決方案：刪除被監控主機/tmp下的檔案192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9

   rm /tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9
