zabbix4.2学习笔记--监控nginx

图解一个客户端连接开源版本的Nginx情况

Accepts（接受）、Handled（已处理）、Requests（请求数）是一直在增加的计数器。Active（活跃）、Waiting（等待）、Reading（读）、Writing（写）随着请求量而增减。

环境

主机	ip	zabbix版本	关系
centos7.5	192.168.181.135	zabbix4.2	服务端
centos7.5	192.168.181.136	zabbix4.2	客户端

Nginx相关指标的收集

首先在nginx配置文件中打开stub_status功能，并通过nginx -s reload命令重新加载配置文件

vim /usr/local/nginx/conf/nginx.conf

server {
    # zabbix监控nginx基本活跃指标
    location /ngx_status {
        stub_status on;
        access_log off;
        allow 192.168.181.0/24;
        allow 127.0.0.1;
        deny all;
        }

nginx -s reload

zabbix客户端配置脚本指令

cat /etc/zabbix/zabbix_agentd.d/userparameter_nginx.conf

UserParameter=nginx.status[*],/etc/zabbix/scripts/ngx-status.sh $1

创建文件夹

mkdir /etc/zabbix/scripts

编辑ngx-status.sh脚本

#!/bin/bash

编辑完成添加执行权限并重启客户端

chmod +x /etc/zabbix/scripts/ngx-status.sh
systemctl restart zabbix-agent
