minimalistic check_disk.sh

Another but minimalistic disk check/status plugin. This script will show only local file-systems, local partitions are sorted from the most in use (as occupancy).

Generic check_disk plugin gives too much information so this script is intended to have at glance disk space occupancy and remaining space; a clean and more readable view of local file-systems.

Tested on: Debian 11/12 and Ubuntu 18/20/22

note: remember to assign execute permission to the script (chmod +x check_disk.sh)

=========

Usage: check_disk.sh -w WarningLevel -c CriticalLevel -x ExcludePartition1,ExcludePartition2,etc...

example => check_disk.sh -w 20 -c 10
example => check_disk.sh -w 20 -c 10 -x /var
example => check_disk.sh -w15 -c10 -x/var,/tmp

-w = % warning level free space left as integer {def: 12}
-c = % critical level free space left as integer {def: 9}
-x = comma separated exclude list
--help = this help
