Usage :
|
|
$0 [-w age_warning_limit] [-c age_critical_limit] [-W files_number_warning_range] [-C files_number_critical_range] -b find-basedir -f find-name-regexp [[-w...] -f find-name-regexp] ...
|
|
|
|
Note: Since the file(s) are checked against the lastest ranges given, order
|
|
of the arguments are important.
|
|
|
|
Default values:
|
|
age_warning_range (in days): $RANGE_WARNING_AGE
|
|
age_critical_range (in days): $RANGE_CRITICAL_AGE
|
|
files_number_warning_range : $RANGE_WARNING_FILES_NUMBER
|
|
files_number_critical_range : $RANGE_CRITICAL_FILES_NUMBER
|
|
find-basedir: $FIND_BASEDIR
|
|
|
|
The check is only done on the couple crit-crit and warn-warn.
|
|
No combination of crit/warn is made (for example, critical number of
|
|
files at age warning range).
