本节介绍的几段shell脚本,可以用于提取磁盘的I/O信息,系统负载Load信息等

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

2,代码2

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

3,代码3

复制代码 代码如下:

#!/bin/sh

PDIR=/monitor/nagios/shell/sarlog

runday=$(date +%Y-%m-%d)

TmpDir=/monitor/nagios/shell/sarlog/log

Machinelst=/monitor/nagios/shell/sarlog/machine.lst

for i in `/bin/cat /monitor/nagios/shell/sarlog/machine.lst`

do

/usr/bin/scp ${i}:/tmp/*${runday}sar.txt ${TmpDir}

/usr/bin/scp ${i}:/tmp/*${runday}load.txt ${TmpDir}

done

/bin/cat ${TmpDir}/*${runday}sar.txt >> ${TmpDir}/Tmp${runday}.txt

/bin/cat ${TmpDir}/*${runday}load.txt >> ${TmpDir}/${runday}loadResult.txt

count=1

Line=$(cat ${TmpDir}/Tmp${runday}.txt |wc -l)
