获取磁盘IO与系统负载Load的shell脚本

1，提取系统负载信息

复制代码

代码如下:

#!/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

复制代码

代码如下:

#!/bin/sh

PDIR=/monitor/nagios/shell/sarlog

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 &

done
