监控脚本：监控每台机器的内存使用率>70%,则输出报警信息
#！/bin/bash mem_used=`free | awk ‘NR==2{print $3}‘` mem_total=`free | awk ‘NR==2{print $2}‘` x=`expr "scale=2; $mem_used/$mem_total" |bc -l |cut -d. -f2` if ((x>70)); then echo "Your memory is using $x\%, please handle as soon as possible." else echo "Your memory usage is $x%, can be at ease use!" fi
