zabbix agent配置
安裝agent包
#安裝agent包
[root@17-Cobbler web]# yum -y install zabbix-agent
#編輯agent配置文件路徑：/etc/zabbix/zabbix_agentd.conf
[root@17-Cobbler zabbix]# vim zabbix_agentd.conf
#修改被動的Server，主動的ServerActive
Server=192.168.0.17
ServerActive=192.168.0.17
Hostname=17-Cobbler
#啓動zabbix-agent服務
[root@17-Cobbler zabbix]# systemctl start zabbix-agent
#查看服務運行情況
[root@17-Cobbler zabbix]# systemctl status zabbix-agent

自定義監控
第一步：
#開啓stub_status模塊
--with-http-stub-status_module
第二步：
#nginx打開監控項：
http {
server {
listen 8080;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
location /nginx-status {
stub_status on;
access_log off;
}
}
}
第三步：
#打開測試頁面
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略過）：
#Centos6.x打開zabbix_agent默認路徑爲：/etc/zabbix/zabbix_agentd.conf
#CentOS 6.x與CentOS 7目錄名字不太一樣，統一改成名字吧
[root@nginx-01 conf]#vim /etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd/
[root@nginx-01 conf]#mkdir /etc/zabbix/zabbix_agentd.d
[root@nginx-01 conf]# 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：
#客戶端通過正則匹配nginx的活動連接數
[root@nginx-01 conf]# 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，命名爲nginx.active
[root@nginx-01 zabbix]# 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
[root@nginx-01 zabbix]# 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設置完重啓
[root@nginx-01 zabbix]# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent: [ OK ]
Starting Zabbix agent: [ OK ]
#CentOS7.x重啓
[root@17-Cobbler zabbix]# systemctl restart zabbix-agent
第六步：
#服務端測試
#查看是否安裝了zabbix-get，如果沒有安裝可以通過：yum -y install zabbix-get安裝,至於yum源裏面沒有，可以去阿里雲配置yum源
[root@17-Cobbler zabbix]# rpm -qa | grep zabbix-get
zabbix-get-3.0.14-1.el7.x86_64
#測試
[root@17-Cobbler zabbix]# zabbix_get -s 192.168.0.4 -p 10050 -k nginx.active
1
#客戶端添加完成，剩下服務端web添加。
