Need Script for monitoring directory growth ...

[TSch]

Hi folks,

I'd like to use a script that monitors a certain directory (including all subdirectories) and as soon as there are any new files written into this directory sends out an email ...

I'm afraid I'n not much of a scripter ...
Is there anyone who can help me ?

Thanks in advance !

Regards, Thomas

Read the nmon guide. It will tell you how to script data collection for certain resources. It then puts the data in a form that the nmon analyzer will read into Excel and graph everything out for you.

Hi folks,

it's a great tool
I just downloaded and tested it and it's awesome ...
We certainly have good use for it !
Thanks a lot !

But the problem here is that I need some kind of script telling me via email as soon as there are files being written into a certain directory or any of it's subdirectories ...

Regards
Thomas

Do you want to monitor size or writes? If you want to monitor the % full, that can be done with WSM not to mention a bunch of other scripts out there. I guess if you want to monitor file writes, you could modify one of those scripts to e-mail you everytime the free space drops ...

vi disk_check.sh

df -k|grep 108|awk '{print $4}' > file1
cut -c 1-2 file1 > file2

a=`cat file2`

if [ $a -ge "20" ];then
echo "files exist"
else
echo "No Files"
fi

:qw!

** replace 108 with your filesytem name **
** replace echo with echo "Disk activity" | /usr/bin/mailx -c "you@youmail.com"

Run it from crontab

crontab -e

0,5,10,15,20,25,30,35,40,45,50,55 * * * * disk_check.sh
:wq!

Not perfect:Not tested

mrn,

sometimes the files that are written to the directory are small enough not to affect the percentage of the FS usage.
I would count the files/dirs once in a awhile,and issue an email if the count grows:
====================================
#!/bin/ksh

#NUMFILES = this is the file that holds last number of files and directories
#NEW_NUMFILES = this is the file that holds the new number of files and directories

###### main ######
#add this script to the crontab
crontab –l |grep “$0” > /dev/null
if [[ $? != 0 ]] ;then
crontab –l > /tmp/crontab1
echo “0,5,10,15,20,25,30,35,40,45,50,55 * * * * `pwd`/$0” >> /tmp/crontab1
crontab /tmp/crontab1
fi

#change /home to your FS name
path1=”/home”

#Update the log with the new number of files in the path
ls -latR $path1|wc –l > /NEW_NUMFILES
#mail if the new number is bigger then the previous one
if (( `cat /NEW_NUMFILES` > `cat /NUMFILES` )) ;then
mail –s “New file/directory were created in the $path1” youname@ppp.com < /NEW_NUMFILES
fi
cp /NEW_NUMFILES /NUMFILES
