3.1 Grafana简介
Grafana是一款开源的数据可视化工具，使用 Grafana 可以非常轻松的将数据转成图表(如下图)的展现形式来做到数据监控以及数据统计。
结合zabbix能够展现更直观的图形界面

3.2 安装grafana
官网指南
由于是学习使用，我们这里选择OSS版本
[root@dbc-server-554 grafana]# wget https://dl.grafana.com/oss/release/grafana-9.3.6-1.x86_64.rpm

3.3 启动grafana
[root@dbc-server-554 grafana]# systemctl start grafana-server.service
[root@dbc-server-554 grafana]# systemctl enable grafana-server.service
Created symlink from /etc/systemd/system/multi-user.target.wants/grafana-server.service to /usr/lib/systemd/system/grafana-server.service.
[root@dbc-server-554 grafana]# systemctl status grafana-server.service
● grafana-server.service - Grafana instance
Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; enabled; vendor preset: disabled)
Active: active (running) since Wed 2023-02-15 11:50:56 CST; 18s ago
...
[root@dbc-server-554 grafana]# ss -nltp|grep grafana
LISTEN 0 128 [::]:3000 [::]:* users:(("grafana-server",pid=3629,fd=20))
可以看到grafana的对外端口号为3000
3.4 登录控制台
访问http://192.168.5.54:3000
如果无法登录，如下
解决方法：1.重启下grafana服务，2.换个浏览器，例如，使用chrome登录
登录账号及密码均是admin，按照提示修改密码，然后我们就进入了控制台
3.5 链接zabbix
Configuration -> data source ->Add data source
1.安装zabbix插件
默认没有安装zabbix插件，所以我们需要安装zabbix的数据源插件
安装方式：https://grafana.com/grafana/plugins/alexanderzobnin-zabbix-app/?tab=installation
1.Install the Application
Use the grafana-cli tool to install Zabbix from the commandline:
grafana-cli plugins install alexanderzobnin-zabbix-app
The plugin will be installed into your grafana plugins directory; the default is /var/lib/grafana/plugins. More information on the cli tool.
Alternatively, you can manually download the .zip file and unpack it into your grafana plugins directory.
[root@dbc-server-554 grafana]# grafana-cli plugins install alexanderzobnin-zabbix-app
✔ Downloaded and extracted alexanderzobnin-zabbix-app v4.2.10 zip successfully to /var/lib/grafana/plugins/alexanderzobnin-zabbix-app
Please restart Grafana after installing plugins. Refer to Grafana documentation for instructions if necessary.
[root@dbc-server-554 grafana]# systemctl restart grafana-server.service
2.启用插件
Enable
现在我们可以查到zabbix的数据源了
3.链接数据源
URL改为zabbix的服务器IP：http://192.168.5.54/api_jsonrpc.php
添加zabbix账号密码，并点击save & test
链接成功
4.导入仪表盘
5.创建仪表板
6.创建仪表盘
这里使用默认监控内容，监控CPU空闲率
类似，我们在创建内存使用率和硬盘读写速率的仪表盘，内容看起来充实了不少
7.添加自建监控项
最后把我们的user_login_max加上
保存仪表板
8.监控信息
增加登录人数，可以看到user login max已经报红了
