• 6、创建Template lihao模板的图形，将以上5个监控项制作成图形
• 7、创建聚合图形，将监控项cpu1分钟平均负载和有多少个用户连接agent端图形制作成聚合图形
• 8、收藏该聚合图形，让其在仪表板中显示
• 9、创建触发器，设置超过7个用户连接agent端，发出告警信息。

1、将zabbix server添加到zabbix web监控平台

[root@localhost ~]# hostnamectl set-hostname server
[root@localhost ~]# bash
[root@server ~]# vim /etc/hosts
[root@server ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.181.159 server
192.168.181.164 agent
[root@server ~]#
[root@server ~]# vim /etc/zabbix/zabbix_agentd.conf
Hostname=server         //将次处150行修改为仅主机
[root@server ~]# systemctl  restart zabbix-server.service
[root@server ~]#  systemctl enable --now zabbix-agent.service

[root@server ~]# yum -y reinstall glibc-common

2、将zabbix agent添加到zabbix web监控平台

设置客户端
[root@localhost ~]#
[root@localhost ~]# hostnamectl set-hostname agent
[root@localhost ~]# bash
//指定服务端ip将其印射主机传输
[root@agent ~]# scp root@192.168.181.159:/etc/hosts /etc/hosts
The authenticity of host '192.168.181.159 (192.168.181.159)' can't be established.
ECDSA key fingerprint is SHA256:3XDU3TtwMGdfiroUfWwTW5+GXVAMn1LpoJrkFlxQAFA.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '192.168.181.159' (ECDSA) to the list of known hosts.

[root@agent yum.repos.d]# vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.47.137              //指定服务端主机
ServerActive=192.168.47.137
Hostname=agent
Failed to restart zabbix-s.service: Unit zabbix-s.service not found.
[root@agent yum.repos.d]# systemctl restart zabbix-server.service
[root@agent yum.repos.d]# systemctl enable --now zabbix-agent.service

打开浏览器点击配置选择主机点击创建主机

添加成功agent已加入监控平台中

3、为zabbix agent创建自定义模板 Template zlh

点击配置选择模板点击添加模板

设定模板名称和群组

点击添加后返回可以看见模板已经被添加进去

为agent1设定tenplate zlh模板点击配置选择主机点击agent

选择模板将tenplate添加进去并点击更新

可以看到已经添加完成

4、基于Template lihao模板创建自定义监控项

（1）要求监控cpu1分钟平均负载 应用集为cpu

点击配置选择主机点击监控项

点击创建监控项

选择键值为cpu平均负载并设定监听所有cpu一分钟的平均负载并设定应用集为cpu

（2）要求监控cpu5分钟平均负载 应用集为cpu

点击配置选择主机点击监控项

点击创建监控项

（3）要求监控cpu15分钟平均负载 应用集为cpu

点击配置选择主机点击监控项

点击创建监控项

选择键值为cpu平均负载并设定监听所有cpu五分钟的平均负载并设定应用集为cpu

（4）要求监控agent的ssh服务的22端口 应用集为ssh

点击配置选择主机点击监控项

点击创建监控项

选择键值为监听tcp服务是否成功运行将sshIP地址和端口填写到对应的地址并指定应用集为ssh，然后添加

（5）自定义键值logusers，该键值要求监控有多少个用户连接agent端 应用集为ssh

在agent客户端中/etc/zabbix/zabbix_agentd.conf配置文件进行编写

[root@agent ~]# vim /etc/zabbix/zabbix_agentd.conf
UserParameter=logusers,who | wc -l
[root@agent ~]# systemctl restart zabbix-agent.service

点击配置选择主机点击监控项

点击创建监控项

指定名称，然后指定键值，键值要与我们设定好了的名字一样，设定应用集为ssh

6、创建Template lihao模板的图形，将以上5个监控项制作成图形

点击配置选择主机点击图形

点击创建图形

设定名称选择监控项点击添加

重复四次

7、创建聚合图形，将监控项cpu1分钟平均负载和有多少个用户连接agent端图形制作成聚合图形

点击监测选择聚合图形点击创建聚合图形

设定名称点击添加

选择tu点击编辑聚合图形

点击更改

选择图源点击添加

重复一次完成

8、收藏该聚合图形，让其在仪表板中显示

点击监测仪表板点击常用的拓扑图的设置将其改为聚合图形，然后点击添加

9、创建触发器，设置超过7个用户连接agent端，发出告警信息。

点击配置选择主机点击触发器

点击添加触发器

填写名称与报警等级和添加报警条件
