Nagios Support Forum

Hi,

i have created my own custom plugin in perl that is,

#!/usr/bin/perl
#
# check_file_exists.pl
#
# Checks if a file exists.
#


use POSIX;
use lib "/usr/local/nagios/libexec" ;
use utils qw($TIMEOUT %ERRORS); # Import predefined status-codes and timeout variable

sub print_usage() {
print "Usage: check_file_exists -f <filename> [-t <timeout>]\n";
}

sub print_help() {
print_usage();
print "\n";
print "Options:\n";
print "-f|--filename (string)\n";
print " set the filename to check for existance\n";
print "\n";
}

for($i = 0; $i < $#ARGV; $i++) {
if($ARGV[$i] =~ /^-h|^--help/) { # Help argument
print_help();
exit($ERRORS{"OK"});
}
elsif($ARGV[$i] =~ /^-f|^--filename/) { # filename argument
$i++;
$filename = $ARGV[$i];
}
elsif($ARGV[$i] =~ /^-t|^--timeout/) { # timeout argument
$i++;
$TIMEOUT = $ARGV[$i];
}
else { # Unknown argument, print help
print_usage();
exit($ERRORS{"UNKNOWN"});
}
}

if (!defined($filename)) {
# No filename was given.
print_usage();
exit($ERRORS{"UNKNOWN"});
}

# Timeout handler used
$SIG{'ALRM'} = sub {
print "CRITICAL: Plugin timed out after $TIMEOUT seconds\n";
exit($ERRORS{'CRITICAL'});
};

# Install timeout handler, so that the plugin does not hang indefinitely.
alarm($TIMEOUT);

if (-f $filename) {
print "OK - Filename $filename exists.\n";
exit($ERRORS{"OK"});
} else {
print "CRITICAL - Filename $filename does not exist.\n";
exit($ERRORS{"CRITICAL"});
}

i add command and service in command.cfg and windows.cfg respectivly the command code is,
# 'check_file_exists'
define command{
command_name: check_file_exists
command_line: $USER1$/check_file_exists -H $HOSTADDRESS$
}

service code is,
define service{
use generic-service
host_name musewerx-72c7b0
service_description File
check_command check_file_exists
}

then i copy the perl file where all other plugins are located and run it at terminal it results fine then i convert it to binary file using perlcc commant ant try to run it it runs fine at terminal but when i add service and command perameters it give error ,

[root@localhost libexec]# service nagios restart

Try getting rid of the colons in the mentioned configuration.

Running "nagios -v $config_file" is almost ALWAYS of assistance when the instance won't start.

as you told me i tried to do it but get error that is,

[root@localhost ~]# nagios -v $config_file
bash: nagios: command not found


what should i do now hopes for suggestions ..

Thanks in Advance.

You need to point to the actual location of the nagios binary and the main nagios.cfg file. On a source install it looks like:
