Project Notes
For help and list of options do: ./check_files.pl --help The documentation in the help should be enough to get you started. The plugin despite large amount of code (to support threshold spec) is not that complex - all it does is sum number of files and alert if its too many, plus optionally track what is the oldest file. The plugin is based on check_netstat.pl 0.35 and as such shares threshold spec syntax with all my other plugins and supports slightly extended nagios plugin specification threshold syntax. The plugin itself does "ls -l" and parses that data. Depending on the options it can also add "-R" for recursion or may try to list only specific files you're looking for for large directories. I've chosen parsing "ls -l" over doing lower level direntry calls because parsing allows to use the plugin to process results from a remote system where all you need to do is execute "ls -l". To support such use the plugin has "-I" parameter telling plugin to process STDIN data as "ls -l" as well as "-C" parameter which allows to specify command in place of "ls -l" so you can substitute ssh or something else in there. Example of use is: define command { command_name check_err_files command_line $USER1$/check_files.pl -f -D $ARG1$ -F $ARG2$ -w $ARG3$ -c $ARG4$ } define service{ use prod-service host_name you_know_who service_description File Checks for error files check_command check_err_files!/var/someplace/somewhere!"*.error"!2!5 } If executing this remotely by snmp (which is rare, but I do it this way) example is: define command { command_name check_bysnmp_errfiles command_line $USER1$/check_by_snmp.pl -E someplace_fileslist -H $HOSTADDRESS$ -l snmpuser -x 'onesecret' -L sha,aes -X 'anothersecret' -S --exec $USER1$/check_files.pl -f -I -F $ARG1$ -w $ARG2$ -c $ARG3$ }

files with spaces not count
by future001, April 30, 2016
1st - I needed to comment out lines 742-745 too!
2nd and worth: I'm would like to check mounted Windows directories and there are a lot of files with 'spaces'. These files are ignored by the script.
Example: -F *.jpg ... in dir are 5 files, and only 2 are counted because in 3 are spaces like "hallo world.jpg" or "hallo-world 001.jpg"

Please fix it - Thanks!

does not work
by dappa_don, February 28, 2015
[root@nagios-01]# /usr/local/nagios/libexec/check_files.pl -D /some/directory/ -F '*.txt' -c ! 27 -r -L "File Count"
File Count CRITICAL - *.bk is 27 (not equal to )

Does the job and is very well written
by achoo, November 30, 2013
This works great except I needed to comment out lines 742-745.

if (!defined($o_stdin) && !close(SHELL_DATA)) {
print "UNKNOWN ERROR - execution of $shell_command resulted in an error $? - $!";
exit $ERRORS{'UNKNOWN'};
}

These lines are giving the me the error "UNKNOWN ERROR - execution of LANG=C ls -l -R resulted in an error 512 - ' on my system (RHEL6, perl5 (revision 5 version 10 subversion 1)).

'UNKNOWN ERROR - execution of LANG=C ls -l -R resulted in an error 512 - Bad file descriptor' is the error if I just do a 'close(SHELL_DATA)'
