验证管理节点config.ini参数配置的shell脚本,看memory是否超标,运行的时候需要附带上面data node id,而且cluster要处于工作状

验证管理节点config.ini参数配置的shell脚本,看memory是否超标,运行的时候需要附带上面data node id,而且cluster要处于工作状态,最起码manage node和data node要处于启动状态

run check_memery.sh

脚本内容下:

# 注明,,是从网友飞鸿大哥那里趴过来,改改运行通过的,肯定有很多需要完善的地方,欢迎大家提出宝贵的意见。

#!/bin/bash

usage()
{
  echo "-----------------------------"
  echo "Usage:$(basename $0) NodeId"  #数据节点的ID
  echo "-----------------------------"
  echo
  exit 1
}


print_size ()
{
string1=$(echo $1|sed -e :a -e 's/^.\{1,40\}$/&./;ta')
echo -e "$string1 (MB):\t$2"
}

if [ "$1" == "" ]; then
    usage
fi
string1=$(echo $1|egrep "^[0-9]+$")
if [ "$1" != "$string1" ]; then
    usage
fi
