Filesystem ??

Here is what the output of the df command

$df -h
Filesystem Size Used Avail Use% Mounted on
/dev/dasda1 2.2G 1.0G 1.1G 50% /
/dev/dasdb1 2.2G 1.1G 1.0G 51% /usr
/dev/dasdc1 2.2G 234M 1.9G 11% /var
/dev/dasdd1 2.2G 1.2G 972M 55% /opt

is there an easy way to key off of the Use% field.

Code:
df -h | grep "%" | awk  '{printf("%s\n", $5)}'

This will pull off just the percentages.

How do I Key off % utilization for notification?

That command give me.

df -h | grep "%" | awk '{printf("%s\n", $5)}'
Use%
50%
51%
11%
55%

Now How would I key off the percentages to notify me when it gets above 80%?

Sorry, I didn't understand the term "key off" in the context that you were using. I'll take a gander at that after lunch if someone else hasn't already answered.

If you call this routine with a cronjob, it should do what you want.

Code:
#!/usr/bin/perl

# auswipe, 5 Apr 2002
# Tested under OpenBSD 2.9
# auswipe sez : "No guarantees!"

$upperLimit = 80;              # Upper Limit in % for a File System
$mailTarget = "joe\@blow.com"; # Target for the automatic e-mail message

open(STATS, "df -h\|grep '%'|") || die "$!";

my @fileStats = <STATS>;

foreach $entryLine (@fileStats) {
  chomp($entryLine);
  $entryLine =~ s/\s+/ /g;
  my @fsStats = split(/ /, $entryLine);
  $fsStats[4] =~ s/%//g;
  if ($fsStats[4] >= $upperLimit) {
    open(MAIL, "|mail -s \"FileSystem $fsStats[0] Getting Full!\" $mailTarget ") || die "Can't open m
ail!";
    select(MAIL);
    print << "EOF";

    The FileSystem $fsStats[0] is getting full.
    Currently, the file system is ${fsStats[4]}% full. The upper
    limit has been placed at ${upperLimit}%.

    Please attend to this matter.

EOF
    close(MAIL);

  };
};
close(STATS);

Customer the target e-mail address accordingly (please note the \@ for @) and give it a try. If you have any problems, please let me know.
