Filesystem monitoring
A script where we need to come up with a way for the disk space monitoring to be smarter. On smaller file systems, we still want to alert at 90% full, but on larger file sytems, we should only alert when there is only a few GB free.
Can someone please shed some light on this?

There is multiple options, but you need modify below script as per your requirement.
#!/usr/bin/awk -f
BEGIN{
ADMIN="root@localhost"
threshold=20
"date" | getline date
"uname -n" | getline hostname
while("LC_ALL=C df -Ph" | getline){
used=$5
if($1 != "Filesystem" && int(used) >= threshold){
print "Running out of space: "$1,used" used on "hostname" as on: "date
print "mail -s "Alert: Almost out of disk space: " $1,used" used" "ADMIN" >/dev/null" | "sh"
close("sh");
}
}
}

Parsing the lines ofdfwill break as soon as the mount reaches a certain amount of characters thatdfwill print it on multiple lines.

@gertvdijk No, it's ok withdf -P, it's designed to be easily parsable (except when device names can contain whitespace).

You could (ab)use the Nagios plugin check_disk for this. The advantage is that this piece of software is lightweight, well-tested and probably available by your package management already (Debian/Ubuntu package nagios-plugins-basic). Example usage:
check_disk -w 10% -c 3 -u GB -p / -p /mnt
In this example, it checks two mointpoints / and /mnt. If it exits with a exit status of 2, your disk has less than 3GB available, if it exits with status 1, it has less than 10% available and if it exits with a status of 0, then neither of the values is reached. Checking for exit status in Bash is trivial, i.e. $?.
