获取磁盘IO与系统负载Load的shell脚本

1，提取系统负载信息

#!/bin/sh
host=$(hostname)
channel=$(hostname | sed 's/[0-9]//g')
runday=$(date +%y-%m-%d)
iphost=$(/sbin/ifconfig  | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}')
i=1
 while [ $i -le 120 ];do
 rundaytime=$(date "+%y-%m-%d %h:%m:%s")
 /bin/cat /proc/loadavg | awk -f " " '{print "'"$rundaytime"'"","$1","$2","$3","$4","$5}' >> /tmp/$(hostname)-${runday}load.txt
 /usr/bin/sar -u 1 1 | grep -v average | /bin/sed -n '4,$p' | awk -f " " '{print "'"$rundaytime"'"","$4","$6","$7","$9}'  >>  /tmp/$(hostname)-${runday}sar.txt
 i=$((i+1))
 sleep 59
done
awk -f "," '{print "'"$host"'"",""'"$channel"'"",""'"$iphost"'"","$1","$2","$3","$4","$5}' /tmp/$(hostname)-${runday}sar.txt > /tmp/$(hostname)${runday}sar.txt
awk -f "," '{print "'"$host"'"",""'"$channel"'"",""'"$iphost"'"","$1","$2","$3","$4","$5","$6}' /tmp/$(hostname)-${runday}load.txt  > /tmp/$(hostname)${runday}load.txt
rm -rf /tmp/$(hostname)-${runday}sar.txt
rm -rf /tmp/$(hostname)-${runday}load.txt

2，代码2

#!/bin/sh

runday=$(date +%y-%m-%d)
tmpdir=/monitor/nagios/tmp
for i in `/bin/cat /monitor/nagios/shell/sarlog/machine.lst`
do
   /usr/bin/scp ${pdir}/sarlog.sh ${i}:/root && /usr/bin/rsh ${i} /root/sarlog.sh &
