手把手教你使用 Zabbix 监控 Nginx。
环境介绍：
服务器系统版本：CentOS release 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
# Script to fetch nginx statuses for tribily monitoring systems
# Author: krish@toonheart.com
# License: GPLv2
# Set Variables
BKUP_DATE=`/bin/date +%Y%m%d`
LOG="/data/log/zabbix/webstatus.log"
HOST=127.0.0.1
PORT="80"
# Functions to return nginx stats
function active {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
# Run the requested function
$1
chmod o+x nginx_status.sh
chown zabbix.zabbix nginx_status.sh
ll
total 4
-rwxr-xr-x 1 zabbix zabbix 1273 May 13 17:42 nginx_status.sh
5. 修改 nginx 服务器上 zabbix 客户端的 zabbix_agentd.conf 配置文件，然后重启 zabbix agentd 客户端。
cd /usr/local/zabbix/etc
grep -v "^[#;]" zabbix_agentd.conf | grep -v "^$"
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 waiting6. 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"
88010867. 在网上搜到一个 zabbix 中 nginx status 的模板, 把模板导入 zabbix 服务器。

</zabbix_export>8. 登陆到 zabbix 服务器首页，点击”组态”-“模板”。
点击”汇入”, 如图所示
点击“汇入文件“，然后把找到的 nginx_status.xml 文件，汇入模板。
创建应用集 Nginx Server。
把 nginx 主机连接到模板上去。
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。
