This article mainly introduces how to achieve the access to disk IO and system load Load shell script, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

1. Extract system load information

The code is as follows:

#! / 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 awk-F "'{print"'"$rundaytime"'"," $4 "," $6 "," $7 "," $9}'> > / tmp/$ (hostname)-${runday} sar.txt

ITunes $((iTun1))

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, Code 2

The code is as follows:

#! / 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, Code 3

The code is as follows:

#! / 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)

> ${TmpDir} / Result$ {runday} .txt

While ["$count"-le "$Line"]

Do

Idle=$ (sed-n "${count} p" ${TmpDir} / Tmp$ {runday} .txt | awk-F ","'{print $8}')

Busy= `echo "scale=2;100-$Idle" | bc`

Sed-n "${count} p" ${TmpDir} / Tmp$ {runday} .txt | sed "TmpDir @ / ${runday} sarResult.txt

Let count=count+1

Done
