shell脚本监控

❶ linux上使用shelle脚本如何实时监控文件属性时间更新后，执行另外shell脚本

想必你已经在chinaunix上找到答案了吧。
a=`stat -c %Y filename`;b=`date +%s`;if [ $[ $b - $a ] -gt 180 ];then command;else othercommand;fi就挺好的
但是你要注意在crontab中执行的时候需要加source一下环境变量，不然有些命令会找不到路径。
如：
0-59 * * * * . /etc/profile;a=`stat -c %Y filename`;b=`date +%s`;if [ $[ $b - $a ] -gt 180 ];then command;else othercommand;fi
. /etc/profile可以换成你用户目录下的配置文件.
C shell的为 .cshrc 在用户主目录下
bashell的为 .bashrc 在用户主目录下
kshell的为.profile 在用户主目录下

❷ 如何利用shell脚本监控服务器温度

统:centos 5.5 1.监控服务器状态脚本内容:
01 #!/bin/bash 02
IP=`ifconfig eth0 | grep "inet addr" | cut -f 2 -d ":" | cut -f 1 -d " "`

average_load=`echo "scale=2;a=$load_15/$cpu_num;if(length(a)==scale(a)) print 0;print a" | bc`

❸ 如何用shell脚本监控服务器负载，cpu，内存，硬盘和登录用户数

试试档厅这个方法：告袜Check if this entry is a directory or a file.
const size_t filenameLength = strlen(fileName);
if (fileName[filenameLength-1] == '行友隐/')
{
{

❹ 如何部署linux服务器监控shell脚本

1、查看主机网卡流量

#!/bin/bash
#network
#Mike.Xu
while : ; do
time=’date +%m”-”%d” “%k”:”%M’
day=’date +%m”-”%d’
rx_before=’ifconfig eth0|sed -n “8″p|awk ‘{print $2}’|cut -c7-’
tx_before=’ifconfig eth0|sed -n “8″p|awk ‘{print $6}’|cut -c7-’
sleep 2
rx_after=’ifconfig eth0|sed -n “8″p|awk ‘{print $2}’|cut -c7-’
tx_after=’ifconfig eth0|sed -n “8″p|awk ‘{print $6}’|cut -c7-’
rx_result=$[(rx_after-rx_before)/256]
tx_result=$[(tx_after-tx_before)/256]
echo “$time Now_In_Speed: “$rx_result”kbps Now_OUt_Speed: “$tx_result”kbps”
sleep 2
done

2、系统状况监控

#!/bin/sh
#systemstat.sh
#Mike.Xu
ip=192.168.1.227
top -n 2| grep “Cpu” >>./temp/cpu.txt
free -m | grep “Mem” >> ./temp/mem.txt
df -k | grep “sda1″ >> ./temp/drive_sda1.txt
#df -k | grep sda2 >> ./temp/drive_sda2.txt
df -k | grep “/mnt/storage_0″ >> ./temp/mnt_storage_0.txt
df -k | grep “/mnt/storage_pic” >> ./temp/mnt_storage_pic.txt
time=`date +%m”.”%d” “%k”:”%M`
connect=`netstat -na | grep “219.238.148.30:80″ | wc -l`
echo “$time $connect” >> ./temp/connect_count.txt

3、监控主机的磁盘空间,当使用空间超过90％就通过发mail来发警告

#!/bin/bash
#monitor available disk space
SPACE=’df | sed -n ‘/ / $ / p’ | gawk ‘{print $5}’ | sed ’s/%//’
if [ $SPACE -ge 90 ]
then
[email protected]
fi

4、监控CPU和内存的使用情况

#!/bin/bash
#script to capture system statistics
OUTFILE=/home/xu/capstats.csv
DATE=’date +%m/%d/%Y’
TIME=’date +%k:%m:%s’
TIMEOUT=’uptime’
VMOUT=’vmstat 1 2′
users=’echo $TIMEOUT | gawk ‘{print $4}’ ‘
LOAD=’echo $TIMEOUT | gawk ‘{print $9}’ | sed “s/,//’ ‘
FREE=’echo $VMOUT | sed -n ‘/[0-9]/p’ | sed -n ’2p’ | gawk ‘{print $4} ‘ ‘
IDLE=’echo $VMOUT | sed -n ‘/[0-9]/p’ | sed -n ’2p’ |gawk ‘{print $15}’ ‘
echo “$DATE,$TIME,$USERS,$LOAD,$FREE,$IDLE” >> $OUTFILE

5、全方位监控主机

#!/bin/bash
# check_xu.sh
# 0 * * * * /home/check_xu.sh
DAT=”`date +%Y%m%d`”
HOUR=”`date +%H`”
DIR=”/home/oslog/host_${DAT}/${HOUR}”
DELAY=60
COUNT=60
# whether the responsible directory exist
if ! test -d ${DIR}
then
/bin/mkdir -p ${DIR}
fi
# general check
export TERM=linux
/usr/bin/top -b -d ${DELAY} -n ${COUNT} > ${DIR}/top_${DAT}.log 2>&1 &
# cpu check
/usr/bin/sar -u ${DELAY} ${COUNT} > ${DIR}/cpu_${DAT}.log 2>&1 &
#/usr/bin/mpstat -P 0 ${DELAY} ${COUNT} > ${DIR}/cpu_0_${DAT}.log 2>&1 &
#/usr/bin/mpstat -P 1 ${DELAY} ${COUNT} > ${DIR}/cpu_1_${DAT}.log 2>&1 &
# memory check
/usr/bin/vmstat ${DELAY} ${COUNT} > ${DIR}/vmstat_${DAT}.log 2>&1 &
# I/O check
/usr/bin/iostat ${DELAY} ${COUNT} > ${DIR}/iostat_${DAT}.log 2>&1 &
# network check
/usr/bin/sar -n DEV ${DELAY} ${COUNT} > ${DIR}/net_${DAT}.log 2>&1 &
#/usr/bin/sar -n EDEV ${DELAY} ${COUNT} > ${DIR}/net_edev_${DAT}.log 2>&1 &

放在crontab里每小时自动执行：
0 * * * * /home/check_xu.sh

这样会在/home/oslog/host_yyyymmdd/hh目录下生成各小时cpu、内存、网络，IO的统计数据。如果某个时间段产生问题了，就可以去看对应的日志信息，看看当时的主机性能如何。

❺ aix shell脚本 对某个目录监控

#!/bin/sh
date=`date +%Y%m%d`
find /ftpdata/hjjk/ftp_down/hospital_register -name \
scoure*$date.txt \
chenggong*$date.txt \
quxiao*$date.txt \
user-$date.txt \
yytable-$date.txt \
yymsg-$date.txt \
>result 2>/dev/null
if [ $? -eq 0 ]
then
case file in
"scoure*$date.txt")
cat -n scoure*$date.txt | grep 12 | grep 1\^abc\^2\^abcd \
2>/dev/null
if [ $? -ne 0 ]
then echo "soure*$date.txt is not nomal"
else echo "soure*$date.txt is nomal"
fi
;;
"chenggong*$date.txt")
cat -n chenggong*$date.txt | grep 17 | grep 1\^abc\^2\^abcd \
2>/dev/null && \
cat -n chenggong*$date.txt | grep 17 | grep 1\^abc\^2\^abcd \

if [ $? -ne 0 ]
then echo "chenggong*$date.txt is not nomal"
else echo "chenggong*$date.txt is nomal"
fi
;;

if [ $? -ne 0 ]
then echo "quxiao*$date.txt is not nomal"
else echo "quxiao*$date.txt is nomal"
fi
;;

cat -n user-$date.txt | grep 10 | grep 1\^abc\^2\^abcd \
2>/dev/null && \
cat -n user-$date.txt | grep 9 | grep 1\^abc\^2\^abcd \
2>/dev/null
if [ $? -ne 0 ]
then echo "user-$date.txt is not nomal"
else echo "user-$date.txt is nomal"
fi
;;
"yytable-$date.txt")
cat -n yytable-$date.txt | grep 3 | grep 1\^abc\^2\^abcd \
2>/dev/null
if [ $? -ne 0 ]
then echo "yytable-$date.txt is not nomal"
else echo "yytable-$date.txt is nomal"
fi
;;
"yymsg-$date.txt")
cat -n yymsg-$date.txt | grep 14 | grep 1\^abc\^2\^abcd \
2>/dev/null
if [ $? -ne 0 ]
then echo "yymsg-$date.txt is not nomal"
else echo "yymsg-$date.txt is nomal"
fi
esac

else
echo "file not find"
fi
rm -rf result

❻ 如何监控shell脚本是否执行失败

你好，
举个例子，执行一条基本语句建镇者含立一个文件
#!/bin/bashtouch test.txtif [ $? -eq 0 ]then echo "执行成功"else echo "执行失御笑败"fi$?可以判断上一条命令是否成功，成功为0，不成功为非嫌桥0

❼ 系统之家Linux使用shell脚本监控rsync文件传输的完整性怎么办

#/bin/bashtrue=1F_root=/tmp/某张表Vol=`-ks$F_root|sed's/M//'`whiletruedoif[$Vol>50]thencat/dev/null>$F_rootsleep1800fidone这个脚本一旦运行就无法停止，那个某张表的目录因你个人的情况而设置，因为循环条件whiletrue永远成立，如果要停止监控，只要kill-9"进程号"就可以了

❽ shell脚本，如何监控目录下的文件内容是否被修

监控文件的change time，当有修改时，change time会变

❾ 编写SHELL脚本对某目录下指定文件进行监控

纯手工前碰写出来的燃悔穗啊！
filename=file_`date +%Y%m%d`.txt
filenum=`find /home/oracle -name $filename|wc -l`
if [ $filenum -eq 0 ]
then
echo " file not find! "
else
infonum=`cat /皮卜home/oracle/$filename|grep "\^"|wc -l`
if [ $infonum -eq 0 ]
then
echo "^ not find! "
else
echo " file normal! "
fi
fi
