监控pod 磁盘状态

因为k8s集群版本太低，升级版本太麻烦，所以就通过脚本监控了。

#!/bin/bash

declare -A gbdict

#将AWK内容转成数组
array=($(/usr/local/bin/crictl stats|grep -v CONTAINER|awk '{if($4 ~ "GB")print $1,$4}'))

for(( i=0;i<${#array[@]}-1;i+=2)) do
  gbdict[${array[i]}]=${array[i+1]}

  #获取pod对应的数据量
  pod_disk_size=`echo ${array[i+1]} |awk -F 'GB'  '{print $1}'`
  #比较pod 数据是否大于10G
  big_small=`echo "$pod_disk_size > 10"|bc`

  if [ $big_small -eq 1 ];then

     #echo ${array[i]},${array[i+1]}
     res=`/usr/local/bin/crictl ps -a|grep ${array[i]}|awk  '{print $7,$9}'`
     echo $res > /tmp/check_pod_disk.log
     /opt/scripts/dingding_base_by_url.py "https://oapi.dingtalk.com/robot/send?access_token=xxx" "tke $res pod使用空间超过10G。"
