|
|
|
|
|
#### 3.安装zabbix-agent
|
|
|
|
|
|
略
|
|
|
|
|
|
注意：修改配置文件，关联zabbix-server
|
|
|
|
|
|
#### 4.创建主机群组
|
|
|
|
|
|
略
|
|
|
|
|
|
注意：群组名为kubernetes
|
|
|
|
|
|
#### 5.创建监控项模板
|
|
|
|
|
|
注意：采用自定义key的方式，对应的脚本和配置文件如下（zabbix-agent端）
|
|
|
|
|
|
信息采集脚本：
|
|
|
|
|
|
```shell
|
|
|
#!/bin/bash
|
|
|
#disk io monitor index
|
|
|
|
|
|
#tps 每秒传输次数 它表示每秒磁盘完成的读写操作次数。磁盘的 TPS 越高，意味着磁盘的读写能力越强
|
|
|
|
|
|
disk_tps=`iostat | grep vda | awk '{print $2}'`
|
|
|
|
|
|
#kB_read/s 是衡量磁盘读取速度的指标，表示每秒从磁盘读取的数据量
|
|
|
|
|
|
disk_read=`iostat | grep vda | awk '{print $3}'`
|
|
|
|
|
|
#kB_wrtn/s 是指磁盘的写入速度，表示每秒向磁盘写入的数据量
|
|
|
|
|
|
disk_write=`iostat | grep vda | awk '{print $4}'`
|
|
|
|
|
|
#kB_dscd/s 是指磁盘每秒从缓存中被丢弃的数据量
|
|
|
|
|
|
disk_dscd=`iostat | grep vda | awk '{print $5}'`
|
|
|
|
|
|
#kB_read 表示从磁盘读取的总数据量
|
|
|
|
|
|
disk_read_kb=`iostat | grep vda | awk '{print $6}'`
|
|
|
|
|
|
#kB_wrtn 表示自系统启动以来从磁盘写入的总数据量
|
|
|
|
|
|
disk_write_kb=`iostat | grep vda | awk '{print $7}'`
|
|
|
|
|
|
echo -e "disk_tps=$disk_tps
|
|
|
disk_read=$disk_read
|
|
|
disk_write=$disk_write
|
|
|
disk_dscd=$disk_dscd
|
|
|
disk_kb_read=$disk_read_kb
|
|
|
disk_kb_write=$disk_write_kb"
|
|
|
```
|
|
|
|
|
|
配置文件关联采集脚本：
|
|
|
|
|
|
```shell
|
|
|
UserParameter=disk.io[*],bash /etc/zabbix/disk_io.sh | awk -F "=" '/^$1/{print $$2}'
|
|
|
```
|
|
|
|
|
|
重启服务，配置生效
|
|
|
|
|
|
|
|
|
|
|
|
#### 6.创建主机
|
|
|
|
|
|
注意：采用自动发现，配置自动发现规则，设置动作直接添加主机，关联主机群组和模板
|
|
|
|
|
|
|
|
|
|
|
|
## 三：Grafana配置
|
|
|
|
|
|
#### 1.安装Grafana
|
|
|
|
|
|
```shell
|
|
|
[root@xingdiancloud-grafana ~]# yum install -y https://dl.grafana.com/enterprise/release/grafana-enterprise-10.2.1-1.x86_64.rpm
|
|
|
```
|
|
|
|
|
|
#### 2.运行Grafana
|
|
|
|
|
|
```shell
|
|
|
[root@xingdiancloud-grafana ~]# systemctl start grafana-server
|
|
|
```
|
|
|
|
|
|
#### 3.浏览器访问
|
|
|
|
|
|
注意：默认端口：3000 配置文件：/etc/grafana/grafana.ini 默认用户：admin 默认密码：admin
|
|
|
|
|
|
|
|
|
|
|
|
#### 4.添加数据源插件
|
|
|
|
|
|
```shell
|
|
|
[root@xingdiancloud-grafana ~]# grafana-cli plugins install alexanderzobnin-zabbix-app
|
|
|
```
|
|
|
|
|
|
注意：
|
|
|
|
|
|
插件地址：https://grafana.com/grafana/plugins/all-plugins/?search=za
|
|
|
|
|
|
重启服务使插件生效
|
|
|
|
|
|
```shell
|
|
|
[root@xingdiancloud-grafana ~]# systemctl restart grafana-server
|
|
|
```
|
|
|
|
|
|
Grafana-Web界面启用插件
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
