# Plugin to monitor the size of the specified directory

#################################################################
#
# Parameters understood:
#
# config (required)
# autoconf (optional - checks if the path exists etc, not so advanced feature)
#
#################################################################
#
# Requirements
# - bash (or change first line to sh instead of bash or any other shell)
# - existing and readable directory to scan
# - du command, it exists on most of the *nix operating systems
#
#################################################################
#
# Configuration
#
# directory to check
DIR="/var/cache/apache2/"
# unique id, just in case you got multiple such scripts, change id as needed (i guess it should be obsolete, not tested)
ID=1;
# - make sure that user/group that executes this script has access to the directory you have configured
# otherwise run it as another user, edit plugins-conf.d/munin-node and stuff it with example below code (not suggested)
# remember to remove hashes from the beginning of the lines
#
# [du]
# user root
#
# - by default the value is in MegaBytes, to change it you should edit below line in the script to something else, recognizable by du (see man du)
# du -sm $DIR in MB
# du -sk $DIR in KB
