[Solved] File System Monitoring Script
Hello Scripts Guru

I had created a shell script to monitor the threshold of the file system, but some where it is not giving the correct output. Request to all to hel me out

I am getting the following output
Code:
/dev/vg00/lvol3 mounted on 1865224 10% / is 2097152%
/dev/vg00/lvol1 mounted on 1494288 18% /stand is 1835008%
/dev/vg00/lvol7 mounted on 2614408 75% /var is 10485760%
/dev/vg00/lvol8 mounted on 7469647 6% /var/adm/crash is 8454144%
/dev/vg00/lvol6 mounted on 2189632 58% /usr is 5242880%
/dev/vg00/lvol5 mounted on 2059336 1% /tmp is 2097152%
/dev/vg00/lvol4 mounted on 5109456 59% /opt is 12582912%
/dev/vg00/lv_app mounted on 121818 1% /app is 131072%
31457280 mounted on 72% /app/common is 22302271%

But I need a output, where if file system goes beyond 50% threshold, It should shows me output

Your script:
Code:
#!/usr/bin/ksh
#
# SCRIPT: fs_mon_HP.ksh
# AUTHOR: Indrajit Bhagat
# DATE: 15-10-2010
# REV: 1.1.P
# PURPOSE: This script is used to monitor for full filesystems,
# which is defined as .exceeding. the FSMAX value.
# A message is displayed for all .full. filesystems.

# set -x # Uncomment to debug this script

##### DEFINE FILES AND VARIABLES HERE ####

######## START OF MAIN #############

bdf | tail +2 |awk '{print $1, $2, $4, $5, $6}' > $WORKFILE
# Loop through each line of the file and compare column 2

while read FSDEVICE FSVALUE FSMOUNT
do
  FSVALUE=$(echo $FSVALUE | sed s/\%//g) # Remove the % sign typeset -i FSVALUE
  if [ $FSVALUE -gt $FSMAX ]
  then
       echo "$FSDEVICE mounted on $FSMOUNT is ${FSVALUE}%" \
       >> $OUTFILE
  fi
done < $WORKFILE # Feed the while loop from the bottom!!

if [[ -s $OUTFILE ]]
 then
    echo "\nFull Filesystem(s) on $THISHOST\n"
    cat $OUTFILE
    print

Why?

---------- Post updated at 17:52 ---------- Previous update was at 17:47 ----------

Why not load only what you need:
Code:
bdf | tail +2 |awk '{print $1, $5, $6}' > $WORKFILE



---------- Post updated at 17:57 ---------- Previous update was at 17:52 ----------

after just correcting the bdf line as suggested I get for output:
Code:
Full Filesystem(s) on ant

/dev/vg00/lvol8 mounted on /var is 77%
/dev/vg00/lvol7 mounted on /usr is 88%
/dev/vg00/lvol10 mounted on /sm is 58%
/dev/vg00/lvol6 mounted on /opt is 88%
/dev/vg00/lvol12 mounted on /opt/java is 77%
/dev/vg00/lvol5 mounted on /home is 75%
/dev/esvg01/lvol7 mounted on /tsmx is 51%
/dev/esvg03/lvol13 mounted on /tsmx/storage is 75%
/dev/esvg01/lvol4 mounted on /data/www is 54%
/dev/esvg03/lvol11 mounted on /prd is 65%
/dev/r5vg04/lvol1 mounted on /prd/data/arch is 66%

/dev/esvg03/lvol3 mounted on /prd/data/mnt1 is 98%
/dev/esvg02/lvol3 mounted on /rdm is 53%
/dev/esvg02/lvol4 mounted on /rdm/data is 96%
/dev/esvg02/lvol5 mounted on /octant is 65%

/dev/esvg03/lvol10 mounted on /opt/sas/9.1.3 is 76%
/dev/esvg01/lvol5 mounted on /opt/patrol is 54%
/dev/esvg03/lvol6 mounted on /opt/oracle is 55%
/dev/esvg02/lvol1 mounted on /sas_wks is 76%



---------- Post updated at 17:58 ---------- Previous update was at 17:57 ----------

So what do you want then?

---------- Post updated at 18:00 ---------- Previous update was at 17:58 ----------

And now FMAX=80, and:
Code:
 echo "\n Filesystem(s) above $FSMAX% full on $THISHOST\n"

gives for ouput:
Code:
ant:/home/vbe $ bdf_sample.ksh   

 Filesystem(s) above 80% full on ant

/dev/vg00/lvol7 mounted on /usr is 88%
/dev/vg00/lvol6 mounted on /opt is 88%
/dev/esvg03/lvol4 mounted on /prd/data/mnt2 is 82%
/dev/esvg03/lvol3 mounted on /prd/data/mnt1 is 98%
/dev/esvg02/lvol4 mounted on /rdm/data is 96%
/dev/esvg01/lvol3 mounted on /sm/export is 84%

Just correct your bdf line, and all seems to work...

 Filesystem(s) above 50% full on wdkwe

/dev/vg00/lvol7 mounted on /usr is 73%
/dev/vg00/lvol5 mounted on /opt is 83%
/dev/vg00/lvol4 mounted on /home is 73%


Please suggest how to resolve this error message..I am thinking for using printf to remove the above error. I want o/p of all file system which is exceding the threshold 50 %
