[SOLVED] Disk Space alert

ankitpandey · 04-20-2012, 09:58 AM

Hello,

I want to enable monitoring on space size, if it exceeds certain limit then it should send alert mail. Please help me with this. Environment is Solaris. I found one code from the forum but that is throwing error (test.sh: syntax error at line 9: `percentuse=$' unexpected) to me

Code:

#!/bin/bash

(

unset FILLING

while read outstring;
do
  percentuse=$(echo $outstring | awk '{ print $1}' | cut -d'%' -f1  )
  partition=$(echo $outstring | awk '{ print $2 }' )
  mountedon=$(echo $outstring | awk '{ print $3 }' )

  if [[ $percentuse -ge 90 ]]; then
    FILLING=1
    echo "Filesystem near fill-up : $mountedon"
  fi
done < <(df -Ph | awk '{ print $5 " " $1 " " $6 }')

if [ -z "$FILLING" ]; then
    echo "All filesystem are in safe condition"
fi

) | mail -s "Daily disk space report" me@gmail.com

Please use CODE tags not QUOTE tags around code to make it easier to read. Most easily done by going into Advanced mode and using the # button.

Your code runs OK using bash version 4.1.10, df (GNU coreutils) 8.15 and GNU Awk 3.1.8. What are your versions?

what is /bin/bash in your environment? bash should understand this

You mean /usr/bin/bash or /bin/bash, no?

of course /bin/bash, which is the first line of the script.

I seem to remember a thread a while back asking something similar and pulled this from it:

Code:

for i in `df -h | grep -v capaci | awk '{print $5}' | cut -d% -f1` ; do if [ $i -lt 90 ]; then echo "good" ; else echo "we have a problem on `df -h | grep $i `" ; fi ; done

sample output:

Code:

good
good
good
good
good
good
good
good
good
good
good
we have a problem on /dev/dsk/c0t0d0s6      9.8G   8.8G   994M    91%    /var
good
good
good
good

Here is your script slightly modified to run on Solaris:

Code:

#!/bin/bash

(
  PATH=$(getconf PATH)
  unset FILLING
  while read outstring
  do
    percentuse=$(echo $outstring | awk '{ print $1}' | cut -d'%' -f1 )
    mountedon=$(echo $outstring | awk '{ print $3 }' )
    if [[ $percentuse -ge 90 ]]; then
      FILLING=1
      echo "Filesystem near fill-up : $mountedon"
    fi
  done < <(df -Ph | awk '{ print $5 " " $1 " " $6 }')
  if [ -z "$FILLING" ]; then
    echo "All filesystem are in safe condition"
  fi
) | mailx -s "Daily disk space report" me@gmail.com

@ankitpandey: as already asked, please edit your first posting and replace the quote tags but code ones.

this oneliner is a nightmare, an example how one should not do it..
try this, it is almost the same (just won't print "good", and "we have a problem on")

Code:

df -h |awk 'BEGIN { FS="[ %]*"} ($5+0) > 90 { print $NF } '
