[Zabbix] Nginx 监控

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。
# vi /usr/local/nginx/conf/nginx.conf
    server {
        listen       80;
        server_name  localhost;
 
        #charset koi8-r;
 
        #access_log  logs/host.access.log  main;
 
        location / {
            root   html;
            index  index.html index.htm;
        }
        location /ngx_status {
            stub_status on;
            access_log off;
            allow 127.0.0.1;
            deny all;

        }

2.重启nginx

请依照你的环境重启你的nginx
#ps -ef | grep nginx | grep -v grep | awk'{print $2}' | xargs kill -9
# /usr/local/nginx/sbin/nginx

3.打开status页面

# curl http://127.0.0.1/ngx_status


Active connections: 1
server accepts handled requests
 12826 12826 12832
Reading: 0 Writing: 1 Waiting: 0

 

4.nginx status详解

activeconnections – 活跃的连接数量
server acceptshandled 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.

5. agent端配置

#vi /etc/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.1.208
Hostname=192.168.1.208
Include=/etc/zabbix/zabbix_agentd.d/*.conf
UnsafeUserParameters=1
 
#vi /etc/zabbix/zabbix_agentd.d/userparameter_nginx.conf
UserParameter=nginx.status[*],/etc/zabbix/shell/ngx_status.sh $1
 
# vi /etc/zabbix/shell/ngx_status.sh      # nginx监控脚本
#!/bin/bash
# Description：zabbix监控nginx性能以及进程状态
# Note：此脚本需要配置在被监控端，否则ping检测将会得到不符合预期的结果
 
HOST="127.0.0.1"
PORT="80"
 
#检测nginx进程是否存在
function ping {
    /sbin/pidof nginx | wc -l
}
#检测nginx性能
function active {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
#执行function
$1
 
# chown zabbix -R /etc/zabbix/shell
 
#systemctl restart zabbix-agent
 
 
#手动测试
#zabbix_get -s 192.168.1.208 -p 10050 -k 'nginx.status[ping]'
