(Monitor AFS disk space usage under Nagios)
check_afsspace [-hV] [-c threshold] [-w threshold] [-t timeout] -H host
check_afsspace is a Nagios plugin for checking free space on AFS
server partitions. It uses vos partinfo to obtain the free space
on the partitions on an AFS server and will return an alert if the
percentage of used space exceeds a threshold. By default, it returns a
critical error if the used space is over 90% and a warning if it is over
85% (changable with the -c and -w options).
check_afsspace will always print out a single line of output, giving the critical errors if any, otherwise giving the warnings if any, otherwise listing in an abbreviated form the percentage free space for all partitions.
Change the critical percentage threshold to threshold, which should be an integer percentage. The default is 90.
The AFS file server whose free space check_afsspace should check. This option is required.
Print out this documentation (which is done simply by feeding the script
to perldoc -t).
Change the timeout for the vos partinfo command. The default
timeout is 10 seconds.
Print out the version of check_afsspace and quit.
Change the warning percentage threshold to threshold, which should be an integer percentage. The default is 85.
check_afsspace follows the standard Nagios exit status requirements. This means that it will exit with status 0 if there are no problems, with status 2 if there is at least one critical partition for that server, and with status 1 if there are no critical partitions but at least one warning partition. For other errors, such as invalid syntax, check_afsspace will exit with status 3.
The standard -v verbose Nagios plugin option is not supported and should be. (For example, under -vv we would want to show the actual total, free, and used byte counts, not just the percentages.)
The usage message for invalid options and for the -h option doesn't conform to Nagios standards.
This script does not use the Nagios util library or any of the defaults that it provides, which makes it somewhat deficient as a Nagios plugin. This is intentional, though, since this script can be used with other monitoring systems as well. It's not clear what a good solution to this would be.

Originally written by Susan Feng for use with mon. Updated by Quanah Gibson-Mount to work with Nagios, and then further updated by Russ Allbery <rra@stanford.edu> to support more standard options and to use a more uniform coding style.
