zabbix监控nginx,多亏了容哥(杨容)的帮忙,为了感谢容哥的帮助,写了这篇文章。

环境介绍:

服务器系统版本:CentOSrelease 6.6 (Final)

内核版本:Linux hk_nginx2.6.32-504.3.3.el6.x86_64

ZabbixServer版本:Zabbix server v2.2.2

ZabbixAgent 版本:Zabbix agent v2.2.2

Nginxweb 版本:nginx version: nginx/1.5.8

在zabbix agentd客户端上,查看nginx是否加载了--with-http_stub_status_module。因为zabbix监控nginx是根据nginx的Stub Status模块,抓取Status模块所提供的数据。假如以前没开启,现在想启用StubStatus 模块,在编译nginx 的时候要加上参数 --with-http_stub_status_module,执行./configure && make就可以了,不用make install。不过,一般情况下都是安装了的。

1.在nginx的配置文件中,添加status配置。

location/nginx-status {stub_status on;access_log  off;allow 127.0.0.1;allow 192.168.1.10;  #(zabbix服务器的IP地址,一般是内网地址)deny all;       
}

2.访问设置好的nginx-status链接,如图所示:

3.nginx Status 详细说明:

Activeconnections:对后端发起的活动连接数;

server accepts 2349542:nginx 总共处理了2349542个连接;

handled:成功创建了64603417次握手;

requests:总共处理了8798670请求。

Reading:nginx读取客户端的header数;

Writing: nginx 返回给客户端的header数;

Waiting: nginx 请求处理完成,正在等待下一请求指令的连接。

4.在agentd上编写监控nginx的脚本,并且设置属主和属组为zabbix,赋予执行权限。

cd /usr/local/zabbix/scripts
cat nginx_status.sh            
#!/bin/bash

chown zabbix.zabbix nginx_status.sh
ll

-rwxr-xr-x 1 zabbix zabbix 1273 May 13 17:42 nginx_status.sh

5.修改nginx服务器上zabbix客户端的zabbix_agentd.conf配置文件,然后重启zabbix agentd客户端。

cd /usr/local/zabbix/etc
grep -v "^[#;]" zabbix_agentd.conf | grep -v "^$"
LogFile=/tmp/zabbix_agentd.log
Server=192.168.1.10        #zabbix server端的IP地址
ServerActive=192.168.1.10  #zabbix server端的IP地址
Hostname=192.168.1.5       #本地的IP地址
UnsafeUserParameters=1
##下面的是新添加进去的
UserParameter=nginx.accepts,/usr/local/zabbix/scripts/nginx_status.sh accepts  
UserParameter=nginx.handled,/usr/local/zabbix/scripts/nginx_status.sh handled  
UserParameter=nginx.requests,/usr/local/zabbix/scripts/nginx_status.sh requests  
UserParameter=nginx.connections.active,/usr/local/zabbix/scripts/nginx_status.sh active  
UserParameter=nginx.connections.reading,/usr/local/zabbix/scripts/nginx_status.sh reading  
UserParameter=nginx.connections.writing,/usr/local/zabbix/scripts/nginx_status.sh writing  
UserParameter=nginx.connections.waiting,/usr/local/zabbix/scripts/nginx_status.sh waiting

6.在zabbix server 端进行zabbix_get测试,取到数据了,说明没问题。

/usr/local/zabbix/bin/zabbix_get -s 192.168.1.5 -p 10050 -k "nginx.connections.active"
11
/usr/local/zabbix/bin/zabbix_get -s 192.168.1.5 -p 10050 -k "nginx.connections.waiting"
10
/usr/local/zabbix/bin/zabbix_get -s 192.168.1.5 -p 10050 -k "nginx.connections.writing"
1
/usr/local/zabbix/bin/zabbix_get -s 192.168.1.5 -p 10050 -k "nginx.accepts"           
2350638
/usr/local/zabbix/bin/zabbix_get -s 192.168.1.5 -p 10050 -k "nginx.requests"
8801086

7.在网上搜到一个zabbix中nginx status的模板,把模板导入zabbix服务器。

8.登陆到zabbix服务器首页,点击”组态”-“模板”。

wKiom1VUOtzDR2FzAAIlzKuggu4348.jpg

点击”汇入”,如图所示

wKioL1VUPKmS3wRiAAB1Mt35VYU934.jpg

点击“汇入文件“,然后把找到的nginx_status.xml文件,汇入模板。

wKioL1VUPNeSlK-UAAH-8tQya7Q738.jpg

创建应用集Nginx Server。

wKioL1VUPTnwAezQAABbtoywK4s141.jpg

wKioL1VUPUTwuStlAACIq2wkarI688.jpg

把nginx主机连接到模板上去。

wKiom1VUPAXzDdudAAGVjpOo9xA310.jpg最后,看下是否可以检测到数据,是否可以顺利出图。

到此为止,实验结束。
