概况界面

1.集群中的节点信息

2.节点加权之后的CPU和memery使用率信息（随时间周期刷新）

1777627-20210918134556368-858959230

1.Node资源界面(加载界面)

  • CPU使用量
  • CPU使用率
  • Memery使用量
  • Memery使用率
  • Pod使用情况
  • CPU请求使用率（当前CPU使用率）
  • Memery请求使用率（当前Memery使用率）
  • Disk使用量
  • Disk使用率

1777627-20210918134633801-1440673815

2.Node资源使用情况界面（加载完成）

1777627-20210918134740116-1607220926

3.点击不同的Node获取不同节点的信息界面（如Node2）

1777627-20210918134843922-514307133

4.Pods信息界面（加载中）

1777627-20210918134901698-1393122633

5.Pods信息使用界面（加载完成）

  • 对应于指定应用的CPU使用率和Memery使用率
  • 所有Pods的状态（环状图显示）
  • 对应于集群中每个节点的pods详细信息（列表显示）

1777627-20210918134940394-450097392

6.负载和请求界面（加载效果）

1777627-20210918134959623-1662682191

7.负载和请求界面（加载完成）

  • 对应于每个请求都有一个请求项，包括ID、IP、时间、状态等
  • 使用曲线图展示请求的响应时间，对应有一个请求都有一个响应时间
  • 对应于每个deployment都有一个列表项，其中请求和响应都是针对于rubis-deployment

1777627-20210918135028737-58261103

8.集群中的所有Container信息

  • 包括Container的名称和使用的镜像

1777627-20210918135057903-158545051

8.测试请求与响应

master节点为集群管理端，rubis-deployment部署在node-1节点中，rubis-deployment是一个计算Fibonacci数的应用

8.1 从master节点向rubis-deployment发送请求(3条)

1777627-20210918135357171-1459779052

8.2 从前端查看请求的响应情况（增加了3条请求记录，通过请求耗时可见）

1777627-20210918135413005-1604190072

9.测试集群中pods的手动伸缩（对于集群中的deployment）

9.1 点击减少pod选项（pods列表界面查看结果）

对应于rubis-deployment当前可用pod数量为2，共有2个pods

结果：16min之前创建的对应于rubis-deployment的pod结束了生命周期

1777627-20210918135615972-483909765

9.2 点击增加pod数量

当前，对应于rubis-deployment当前可用pod数量为2，共有2个pods

结果：从node-1的pod列表中可见一个对应于rubis-deployment的pod被创建，创建时间为23s，并不断刷新时间

1777627-20210918135738352-1483318723

与此同时，deployment的信息得到更新:rubis-deployment中ready的pod数量为2/2
