zabbix agent安装与配置、自定义监控
zabbix agent配置安装agent包
#安装agent包
# yum -y install zabbix-agent
#编辑agent配置文件路径：/etc/zabbix/zabbix_agentd.conf
# vim zabbix_agentd.conf
#修改被动的Server，主动的ServerActive
Server=192.168.0.17
ServerActive=192.168.0.17
Hostname=17-Cobbler
#启动zabbix-agent服务
# systemctl start zabbix-agent
#查看服务运行情况
# systemctl status zabbix-agent
● zabbix-agent.service - Zabbix Agent

第一步：
#开启stub_status模块
--with-http-stub-status_module
第二步：
#nginx打开监控项：
http {
server {
listen 8080;
server_namelocalhost;
location / {
root html;
indexindex.html index.htm;
}
location /nginx-status {
stub_status on;
access_logoff;
}
}
}
第三步：
#打开测试页面
http://192.168.0.4:8080/nginx-status
----------
Active connections: 2
server accepts handled requests
6 6 3
Reading: 0 Writing: 1 Waiting: 1
----------
第四步（CentOS 7略过）：
#Centos6.x打开zabbix_agent默认路径为：/etc/zabbix/zabbix_agentd.conf
#CentOS 6.x与CentOS 7目录名字不太一样，统一改成名字吧
#vim /etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd/
#mkdir /etc/zabbix/zabbix_agentd.d
# grep -i Include /etc/zabbix/zabbix_agentd.conf
### Option: Include
#You may include individual files or all files in a directory in the configuration file.
# Include=
# Include=/etc/zabbix/zabbix_agentd.userparams.conf
Include=/etc/zabbix/zabbix_agentd.d/
第五步：
#客户端通过正则匹配nginx的活动连接数
# curl -s http://192.168.0.4:8080/nginx-status | grep "Active" |awk'{print $NF}'
2
# 文件追加到配置文件，命名为nginx.active
# echo -e "UserParameter=nginx.active,/usr/bin/curl -s 'http://192.168.0.4:8080/nginx-status' | grep 'Active' | awk '{print \$NF}'" >/etc/zabbix/zabbix_agentd.d/nginx.active
# cat /etc/zabbix/zabbix_agentd.d/nginx.active
UserParameter=nginx.active,/usr/bin/curl -s 'http://192.168.0.4:8080/nginx-status' | grep 'Active' | awk '{print $NF}'
#CentOS6.x设置完重启
# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent:
Starting Zabbix agent:
#CentOS7.x重启
# systemctl restart zabbix-agent
第六步：
#服务端测试
#查看是否安装了zabbix-get，如果没有安装可以通过：yum -y install zabbix-get安装,至于yum源里面没有，可以去阿里云配置yum源
# rpm -qa | grep zabbix-get
zabbix-get-3.0.14-1.el7.x86_64
#测试
# zabbix_get -s 192.168.0.4 -p 10050 -k nginx.active
1
#客户端添加完成，剩下服务端web添加。
