Zabbix 4.4（五）zabbix监控nginx（自定义nginx监控选项）

实验环境

zabbix-server：
centos 7
192.168.14.216
nginx
centos7
192.168.14.210

介绍：

zabbix默认带有两个nginx的模板，可以直接链接模板使用。本文主要介绍根据实际情况自定义一些监控选项

一、Nginx（192.168.14.210）

1、安装

#配置epel源
[root@nginx ~]# vi /etc/yum.repos.d/epel.repo
[nginx]
name=aliyun epel
baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/
gpgcheck=0
#安装nginx
[root@nginx ~]# yum install -y nginx
#安装zabbix-agent
[root@nginx ~]# rpm -ivh http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
[root@nginx ~]# yum install -y zabbix-agent

2、修改nginx配置文件，为了不影响默认/，添加新的/status

[root@nginx ~]# vim /etc/nginx/nginx.conf
location /status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}

3、查看监控内容

Active connections：当前所有处于打开状态的活动连接数(TCP连接数，即三次握手四次挥手次数)
accepts ：已经接收连接数
handled ：已经处理过的连接数
requests ：已经处理过的请求数，在保持连接模式下，请求数量可能会大于连接数量
Reading: 正处于接收请求的连接数
Writing: 请求已经接收完成，处于响应过程的连接数
Waiting : 保持连接模式，处于活动状态的连接数

4、添加nginx监控选项

#拷贝自带的mysql配置文件并修改为nginx
[root@nginx ~]# cd /etc/zabbix/zabbix_agentd.d/
[root@nginx zabbix_agentd.d]# cp userparameter_mysql.conf userparameter_nginx.conf
#删除有关mysql数据，添加nginx监控选项
[root@nginx zabbix_agentd.d]# vi userparameter_nginx.conf
UserParameter=nginx.active,curl -s http://127.0.0.1/status 2>/dev/null| grep ‘Active’ | awk ‘{print $NF}’
UserParameter=nginx.reading,curl -s http://127.0.0.1/status 2>/dev/null| grep ‘Reading’ | awk ‘{print $2}’
UserParameter=nginx.writing,curl -s http://127.0.0.1/status 2>/dev/null| grep ‘Writing’ | awk ‘{print $4}’
UserParameter=nginx.waiting,curl -s http://127.0.0.1/status 2>/dev/null| grep ‘Waiting’ | awk ‘{print $6}’
UserParameter=nginx.accepts,curl -s http://127.0.0.1/status 2>/dev/null| awk NR==3 | awk ‘{print $1}’
UserParameter=nginx.handled,curl -s http://127.0.0.1/status 2>/dev/null| awk NR==3 | awk ‘{print $2}’
UserParameter=nginx.requests,curl -s http://127.0.0.1/status 2>/dev/null| awk NR==3 | awk ‘{print $3}’

5、开启服务

[root@nginx ~]# systemctl start nginx
[root@nginx ~]# systemctl start zabbix-agent

6、防火墙允许端口访问

[root@nginx ~]# firewall-cmd –permanent –zone=public –add-port=80/tcp
[root@nginx ~]# firewall-cmd –permanent –zone=public –add-port=10050/tcp
[root@nginx ~]# firewall-cmd –reload

二、zabbix-server（192.168.14.216）

1、检查是否安装zabbi_get

[root@zabbix_server ~]# docker ps -a
