Linux系统监控脚本

一个简单的系统监控脚本，有需要的朋友可以参考下。

#!/bin/bash

d=`date +%m%d`
N=`ps -ef | grep httpd | grep -v grep | wc -l`
Q=`ps -ef | grep java | grep -v grep | wc -l`
[ -d /root/check_log/ ] || mkdir /root/check_log

A=`top -bn1 | sed -n '2'p | awk '{print $2}'`
B=`top -bn1 | sed -n '2'p | awk '{print $10}'`
