aix capacity report disk space ?

[alexia32]

Hi guys,

could you tell me what you use when you do a capacity reporting on your aix system for disks ?
I have to do it on my aix servers 5.2..

Thanks for any help advice etc...

Cheers
Al

For filesystems df -g will give you a summary of available, used and free space (in Gb) and inodes.

I want to be good, is that not enough?

I use this script:

df -Pk | awk '$3 ~ /[0-9]/ { print $1,"\t",$3,"\t",substr($5,1,index($5,"%")-1)
}' > df.out

set -A new1 $( awk ' {print $1}' df.out )
set -A new2 $( awk ' {print $2}' df.out )
set -A new3 $( awk ' {print $3}' df.out )

if [[ ! -s out ]]
then
j=0;
cat /dev/null > out
while [[ $j -lt ${#new1[*]} ]]
do
print "${new1[$j]}\t${new2[$j]}" >> out
((j+=1))
done
fi

set -A old1 $( awk ' {print $1}' out )
set -A old2 $( awk ' {print $2}' out )

cat /dev/null > email.txt
i=0;
while [[ $i -lt ${#old1[*]} ]]
do
j=0;
while [[ $j -lt ${#new1[*]} ]]
do
if [[ ${old1[$i]} = ${new1[$j]} ]]
then
if [[ ${old2[$i]} -lt ${new2[$j]} ]]
then
(( temp = ${new2[$j]} - ${old2[$i]} ))
print "${old1[$i]} was increased in size by ${temp}KByte" >> email.txt
break
fi
fi
((j+=1))
done
((i+=1))
done


j=0;
cat /dev/null > out
while [[ $j -lt ${#new1[*]} ]]
do
# This if statement is for Handling exceptions
#(where not to check for higher than 95% filesystems)
if [[ ${new1[$j]} != "test:/orastg" ]]
then
if [[ ${new3[$j]} -ge 95 ]]
then
print "WARNING: ${new1[$j]} is ${new3[$j]}% utilized!!!" >> email.txt
fi
fi
print "${new1[$j]}\t${new2[$j]}" >> out
((j+=1))
done

#cat email.txt

if [[ -s email.txt ]]
then
mail -s "Daily Status Report" "khalid@company.com" < email.txt
fi

# History
echo "======================================================================" >>
 history.out
date >> history.out
echo "======================================================================" >>
 history.out
cat email.txt >> history.out
echo "======================================================================" >>
 history.out
df -Pg >> history.out

# Maintain the size of the history.out file to be 3000 lines only
tail -3000 history.out > temp.out
mv temp.out history.out

This is a handy one liner

print "$(lsvg -Lo |xargs lsvg -L|grep "TOTAL PPs"|awk -F"(" '{print$2}'|sed -e "s/)//g" -e "s/megabytes/+/g"|xargs|sed -e "s/^/(/g" -e "s/+$/)\/1000/g"|bc ) GB"

sub TOTAL for USED or FREE

Hi,
here is the script we use; it checks for all filesystems but the ones in the exclude list which are filled up >= the value given in the variable THRESHOLD. Filesystems which are usually filled above the threshold and don't tend to grow might be a good choice for the exclude list too.
The script is independent from where the column with the %Used is (we had problems having sometimes a different "number of field (NF)" and it does not use df's -P because we had buggy versions of df that didn't recognize -P and so did nothing at all when executing.
We call it about every half an hour via cron.

Here we go:

MAILTO="tom@lala.org"

THRESHOLD=95
TMP_FILE=/tmp/platz.bla.tmp

## Add additional EXCLUDES with '|'
EXCLUDES='proc|mnt'


df | \
grep -vE "\/$EXCLUDES" | \
awk -v threshold=$THRESHOLD '
        BEGIN {
                # Create the header
                printf("%-50s%6s\n","Filesystem:","Filled:")
        }
        # Check which NF has the "%Used"
        NR == 1 {
                for (z=1; z < NF; z++) {
                        if ( $z == "%Used" ) {field=z}
                }
        }
        NR > 1 {
                filled=substr($feld,0,length($feld)-1)
                if ( filled >= threshold ) {
                        printf("%-50s%6s\n",$NF,$field)
                }
        }' > $TMP_FILE

if [[ -e $TMP_FILE && `wc -l $TMP_FILE| awk '{print $1}'` -gt 1 ]]; then
        mail -s "Check filesystems - look at the mail body for details." $MAILTO < $TMP_FILE
else
        echo "Nothing happened."
fi

exit 0

Thanks Guys
I appreciate your help.
Cheers

Oops, just saw I forgot to "translate" 2 variables. "feld" is german for "field", so the line

filled=substr($feld,0,length($feld)-1)

should be

filled=substr($field,0,length($field)-1)

It should work proper then
