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

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）
>${TmpDir}/Result${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 "s/$/,$Busy/g" >> ${TmpDir}/${runday}sarResult.txt
        let count=count+1
done
/usr/local/mysql/bin/mysql -u root -D nagios -pbj7n48dM <<EOF
   load data infile "${TmpDir}/${runday}sarResult.txt" into table t_daily_stats FIELDS TERMINATED BY ",";
   load data infile "${TmpDir}/${runday}loadResult.txt" into table t_daily_load FIELDS TERMINATED BY ",";
EOF
rm -rf ${TmpDir}/*${runday}sar.txt
rm -rf ${TmpDir}/*${runday}load.txt
rm -rf rm -rf ${TmpDir}/*${runday}.txt
