我是一块砖,哪里需要哪里搬!

问题一:使用Grafana查看k8s集群监控情况,提示插件未发现

解决:明显缺少插件,使用grafana-cli命令进行安装即可

root@ymt-130 k8s_installer]# kubectl -n monitoring get pod

installing grafana-piechart-panel @ 1.6.0
from: https://grafana.com/api/plugins/grafana-piechart-panel/versions/1.6.0/download
into: /var/lib/grafana/plugins

✔ Installed grafana-piechart-panel successfully

Restart grafana after installing plugins . <service grafana-server restart>

[root@ymt-130 k8s_installer]# kubectl -n monitoring delete pod grafana-7f94944d5f-g2kdx
pod "grafana-7f94944d5f-g2kdx" deleted

注意: 这里是容器化部署方式,grafana必须做持久化存储才可以,否则无法保存安装数据。

 


问题二:使用Grafana查看k8s集群监控情况,提示没有数据,或者数据显示错误

解决:这是监控指标配置错误导致,选择对应监控->edit,修改相关监控项即可。

指标变化:

io_kubernetes_container_name  ->  pod

node_memory_MemTotal  ->  node_memory_MemTotal_bytes

node_memory_MemFree  ->  node_memory_MemFree_bytes

node_memory_Buffers  ->  node_memory_Buffers_bytes

node_memory_Cached  ->  node_memory_Cached_bytes

node_filesystem_size  ->  node_filesystem_free_bytes

node_filesystem_free  ->  node_filesystem_free_bytes

node_cpu      ->   machine_cpu_cores

基础指标变化:

pod_name      ->   pod

container_name    ->  container
