案例：zabbix 配置 nginx 监控
1. 修改配置文件
vim /usr/local/nginx/conf/nginx.conf
location /nginx_status {
stub_status;
}
说明：
nginx_status 自定义字段，访问地址（例：192.168.169.131/nginx_status）
stub_status 固定参数
# 重启 nginx
./nginx reload
浏览器访问状态说明： Active connections Nginx正处理的活动链接数个数；重要 server Nginx启动到现在共处理了多少个连接。 accepts Nginx启动到现在共成功创建几次握手。 handled requests Nginx总共处理了几次请求。 Reading Nginx读取到客户端的 Header 信息数。 Writing Nginx返回给客户端的 Header 信息数。 Waiting Nginx已经处理完正在等候下一次请求指令的驻留链接，开启。 Keep-alive的情况下，Waiting这个值等于active-（reading + writing）。 请求丢失数=(握手数-连接数)可以看出,本次状态显示没有丢失请求
2. 编写 nginx 监控脚本
#/bin/bash
#Description:Automated monitoring nginx performance and process nginx_status scripts
NGINX_PORT=80
NGINX_COMMAND=$1
nginx_ping(){
/sbin/pidof nginx |wc -l
}
nginx_active(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Active/ {print $NF}'
}
nginx_reading(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Reading/ {print $2}'
}
nginx_writing(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Writing/ {print $4}'
}
nginx_waiting(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Waiting/ {print $6}'
}
nginx_accepts(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $1}'
}
nginx_handled(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $2}'
}
nginx_requests(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $3}'
}
case $NGINX_COMMAND in
ping)
nginx_ping
;;
active)
nginx_active
;;
reading)
nginx_reading
;;
writing)
nginx_writing
;;
waiting)
nginx_waiting
;;
accepts)
nginx_accepts
;;
handled)
nginx_handled
;;
requests)
nginx_requests
;;
*)
echo $"USAGE:$0 {ping|active|reading|writing|waiting|accepts|handled|requests}"
esac# 修改文件权限 chmod u+x /etc/zabbix/zabbix_agentd.d/zabbix_nginx.sh
3. 修改 zabbix 配置文件
vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf # 增加 UserParameter=nginx_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/zabbix_nginx.sh \$1
# 修改完成重启 zabbix-agent systemctl restart zabbix-agent.service
4. 服务端验证
[root@zabbix ~]# zabbix_get -s 192.168.169.131 -k nginx_status[active]
5. 添加模块
模块名称：Template Nginx Web Status Monitor（自定义）
可见名称：NGINX STATUS MONITOR（自定义）
6. 创建应用集
名称：NGINX_STATUS
7. 创建监控项
名称：Nginx_Status_Ping
键值：nginx_status[ping]
8. 定义触发器
超过50个并发连接就执行报警
nginx 服务down了执行报警
9. 关联主机
将需要监控的主机添加上此模板
10. nginx 模板文件
