How to implement the shell script to get disk IO and system load Load
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
