Monitor archived log disk usage

Question

is there an easy way to monitor the disk usage on
archived redo logs (/archive in unix platform) in
plsql (general user if possible)? Thanks.

Answer 1

You cannot easily do it from PL/SQL. You would need to write a shell script to do it.
We use a script that uses df -k and awk to find the percent used foreach ofthe mount points, then depending on thresholds, we send an email.
It goes something like this (O/S Sun Solaris 9.5
filesystems=`df -k|awk '{print $1"!"$6"!95"}'|tail +2`
for f in $filesystems
do
   fs=`echo $f|awk -F! '{print $1}'`
   perc=`echo $f|awk -F! '{print $3}'`
   mnt=`echo $f|awk -F! '{print $2}'`
   chk=`df -k $fs|tail +2|awk '{print $5}'|awk -F% '{print $1}'`
   if [ $perc -lt $chk ]; then
      email dba with $mnt $perc and $chk
   fi
doneThere is, of course, a lot more error checking and stuff, but that is the gist.
