Usage :
|
|
$0 [-w age_warning_limit] [-W files_number_warning_range] [-c age_critical_limit] [-C files_number_critical_range] [-s min_size] -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
|
|
min_size: $MIN_SIZE (c/k/M/G = bytes/kibibytes/mebibytes/gibibytes. Beware of 'find' roundup, cf. man page)
|
|
|
|
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).
|
|
|
|
Little example :
|
|
Let's say you want to check that backup files are recent enough. For example :
|
|
- you expect between 1 and 3 files modified in the last 2 days, warning alert if not,
|
|
- you expect between 2 and 20 files modified in the last 7 days, critical alert if not.
|
|
It gives :
|
|
$0 -W 1:3 -w 2 -C 2:20 -c 7 -b /var/backups -f '*.tar.gz'
|
|
And since '-f' options are executed in sequence, you can combine several check in a single launch :
|
|
$0 -w 2 -W 1:5 -c 7 -C 5:10 -s 1500M -b /var/backups/client1/ -f 'sauv_*.tar.gz' -W 5:50 -C 25:100 -s 2M -b /var/backups/client2/ -f 'sauv_mysql_*.sql.gz'
