Zabbix监控Nginx性能的实现技巧

ASP站长网nginx和php-fpm一样内建了一个状态页，对于想了解nginx的状态以及监控nginx非常有用，为了后续的zabbix监控，我们需要先启用nginx状态页
 
1. 启用nginx status配置
在默认主机里面加上location或者你希望能访问到的主机里面。
 
server {
    location /ngx_status
    {
        stub_status on;
        access_log off;
        allow 127.0.0.1;
        deny all;
    }
}
 
示例：
 
 
upstream lvs_server{
 server 10.27.13.215:8555; #hd_lvs_voice01
 server 10.26.114.166:8555; #hd_lvs_voice02
 server 10.27.62.9:8555; #hd_lvs_voice03
 server 10.30.196.175:8555; #hd_lvs_voice04
 #server 10.30.196.157:8555; #hd_lvs_voice05
 }
 
server {
 listen 8555;
 access_log /var/log/nginx/voice_lvs.access.log main;
 error_log /var/log/nginx/voice_lvs.error.log;
 
location / {
 proxy_pass http://lvs_server;
 }
 
 
location /index {
 proxy_set_header Host $http_host;
 proxy_set_header X-Real-Ip $remote_addr;
 proxy_set_header X-Forwarded-For $remote_addr;
 proxy_set_header Content-Type application/octet-stream;
 proxy_pass http://lvs_server;
 
 }
 location /ngx_status {
 stub_status on;
 access_log off;
 allow 127.0.0.1;
 #deny all;
 }
 
 
}
 
 
2. 重载nginx
 
# nginx -t
# service nginx reload
 
3. 打开status页面
 
# curl 127.0.0.1:8555/ngx_status
Active connections: 2
server accepts handled requests
3091 3091 3254
Reading: 0 Writing: 1 Waiting: 1
 
# curl 127.0.0.1:8555/ngx_status
Active connections: 2
server accepts handled requests
3092 3092 3255
Reading: 0 Writing: 1 Waiting: 1
 
4. nginx status详解
 
active connections – 活跃的连接数量
server accepts handled requests — 总共处理了11989个连接 , 成功创建11989次握手, 总共处理了11991个请求
reading — 读取客户端的连接数.
writing — 响应数据到客户端的数量
waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
 
以上为nginx性能计数，我们除了监控以上数据，还需要监控nginx进程状态，并且配置触发器
zabbix客户端配置
 
编写客户端脚本nginx_status.sh
 
# 检测nginx性能
 
mkdir -p /usr/local/zabbix-agent/scripts
vim /usr/local/zabbix-agent/scripts/nginx_status.sh
 
#!/bin/bash
HOST="127.0.0.1"
PORT="8555"
# 检测nginx进程是否存在
function ping {
 /sbin/pidof nginx | wc -l
}
