监控用途
编写Linux自带的监控脚本化，方便日常运维巡检。
监控脚本
#!/bin/bash
#输入不同字符完成不同巡检内容
#打印提示符
HINT(){
read -p "请按回车继续："
}
#查看CPU信息
CPU_INFO(){
echo
echo -e "\033[4;31mPrint the CPU info:\033[0m"
cat /proc/cpuinfo | awk 'BEGIN {FS=":"} /model name/{print "CPU Model:" $2 }'
cat /proc/cpuinfo | awk 'BEGIN {FS=":"} /cpu MHz/{print "CPU Speed:" $2"MHz"}'
grep -Eq 'svm|vmx' /proc/cpuinfo && echo "Virtualization: Support" || \
echo "Virtualization: No Support"

#查看系统负载

{print "Last 1 minutes system load:"$1"\n""Last 5 minutes system load:"$2"\n"\
