【原創】linux系統監控腳本

一個簡單的系統監控腳本如下：

#!/bin/bash

time=`date +"%Y-%m-%d %H:%M:%S"`

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

IP=`ifconfig eth0 | sed -n '2'p | awk '{print $2}' | awk -F':' '{print $2}'`

M=`uptime | awk '{print $8,$9,$10,$11,$12}'`

O=`ifconfig eth0 | sed -n '8'p | awk '{print $3,$4}'`

P=`ifconfig eth0 | sed -n '8'p | awk '{print $7,$8}'`

R=`ifconfig eth1 | sed -n '8'p | awk '{print $3,$4}'`

S=`ifconfig eth1 | sed -n '8'p | awk '{print $7,$8}'`

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

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